19、,AND REPORTS ON FORM 8-K 47 PART I ITEMS 1 AND 2.BUSINESS AND PROPERTIES General Apache Corporation,a Delaware corporation formed in 1954,is an independent energy company that explores for,develops and produces natural gas,crude oil and natural gas liquids.In North America,our exploration and produc

20、tion interests are focused in the Gulf of Mexico,the Gulf Coast,East Texas,the Permian basin,the Anadarko basin and the Western Sedimentary basin of Canada.Outside of North America,we have exploration and production interests onshore Egypt,offshore Western Australia,offshore the United Kingdom in th

21、e North Sea(North Sea),and onshore Argentina.Our common stock,par value$0.625 per share,has been listed on the New York Stock Exchange(NYSE)since 1969,on the Chicago Stock Exchange(CHX)since 1960,and on the NASDAQ National Market(NASDAQ)since January 2004.On May 18,2006,we filed certifications of ou

22、r compliance with the listing standards of the NYSE and the NASDAQ,including our chief executive officers certification of compliance with the NYSE standards.Through our website,http:/,you can access electronic copies of the charters of the committees of our Board of Directors,other documents relate

23、d to Apaches corporate governance(including our Code of Business Conduct and Governance Principles),and documents Apache files with the Securities and Exchange Commission(SEC),including our annual reports on Form 10-K,quarterly reports on Form 10-Q,and current reports on Form 8-K,as well as any amen

24、dments to these reports.Included in our annual and quarterly reports are the certifications of our chief executive officer and our chief financial officer that are required by applicable laws and regulations.Access to these electronic filings is available as soon as practicable after filing with the

25、 SEC.You may also request printed copies of our committee charters or other governance documents by writing to our corporate secretary at the address on the cover of this report.We hold interests in many of our U.S.,Canadian,and other International properties through subsidiaries,including Apache Ca

26、nada Ltd.,DEK Energy Company(DEKALB),Apache Energy Limited(AEL),Apache North America,Inc.,and Apache Overseas,Inc.Properties referred to in this document may be held by those subsidiaries.We treat all operations as one line of business.Our Growth Strategy Apaches goal is to grow a profitable oil and

27、 gas company for the long-term benefit of our shareholders.Our strategy is to build a portfolio of core areas which provide growth opportunities through both grass-roots drilling and acquisition activity.We now have operations in six countries the United States,Canada,Egypt,the United Kingdom sector

28、 of the North Sea,Australia,and our newest core area Argentina.Whether in our oldest region,the U.S.Central region,or our newest,we seek to grow profitably while building critical mass that supports sustainable,lower-risk,repeatable drilling opportunities,balanced by higher-risk,higher-reward explor

29、ation.We also seek a balance in terms of gas vs.oil,geologic risk,reserve life and political risk.When acquisition opportunities are identified,operational and technical teams participate in the evaluation process,enabling our personnel to move in quickly to execute exploitation activities(including

30、 workovers,recompletions and drilling)that will increase production and reserves,reduce costs per unit produced and enhance profitability.Over time,we build teams that have the technical knowledge and sense of urgency to maximize value.Our local knowledge of producing basins and our proactive cultur

31、e provide a platform for continued growth through strategic acquisitions and drilling.We also periodically evaluate our existing assets to determine whether sales of certain assets will provide opportunities to redeploy our capital resources to rebalance our portfolio and generate better prospective

32、 rates of return.As a result of this process,in January 2006,we sold our 55 percent interest in the deepwater section of Egypts West Mediterranean Concession to Amerada Hess for$413 million,and in August we sold our China holdings to Australia-based ROC Oil Company Limited for$260 million.We reinves

33、ted these proceeds and purchased estimated proved reserves of 109 MMboe in Argentina.More than a decade ago,recognizing that the United States was a mature oil and gas country,we added an international exploration component to our portfolio strategy,which provides exposure to larger reserve targets

34、with 1 which to grow production and reserves through drilling.Apache is also one of the leading acquirers of three-dimensional(3-D)seismic data in the industry today.Our technology experts have developed strategies for rapid and cost-effective acquisition and processing of 3-D data,enabling our tech

35、nical teams to analyze large swaths of acreage and generate drilling prospects on an accelerated timetable.Operating regions are given the autonomy necessary to make drilling and operating decisions and to act quickly.Management and incentive systems underscore high cash flow and rate-of-return targ

36、ets,which are measured monthly,reviewed with senior management quarterly and utilized to determine annual performance rewards.In the United States,the Gulf Coast region consistently delivers high returns on capital invested,as well as cash flow significantly in excess of our exploration and developm

37、ent spending there.Acquisitions play an important role because with steep decline rates,offshore reserves are generally short-lived and difficult to replace through drilling alone.The Central region brings the balance of long-lived reserves and consistent drilling results in the Permian basin of Wes

38、t Texas and New Mexico,East Texas and the Anadarko basin of western Oklahoma.Apaches future growth in the United States is more likely to be achieved through a combination of drilling and acquisitions,rather than through drilling activity alone.Our$821 million Gulf of Mexico acquisition from BP and$

39、269 million Permian basin acquisition from Amerada Hess,for example,complimented our active drilling program in 2006 and buttressed our growth in the U.S.In Canada,we have almost seven million gross acres across the Provinces of British Columbia,Alberta,Saskatchewan and the Northwest Territories.We

40、have a multi-year inventory of low-risk drilling opportunities in a number of Apache fields in Central Alberta,including Provost,Hatton and Nevis,and on acreage acquired in the Exxon Mobil Corporation(ExxonMobil)farm-in agreements of 2004 and 2005.With acquisition and land costs having risen signifi

41、cantly in Canada,these farm-ins provide a way for Apache to earn acreage through drilling with no upfront costs.ExxonMobil retains a royalty on fee lands and a convertible working interest on leasehold acreage,both of which vary dependent on activity levels.We also have opportunities to drill deeper

42、 exploration targets with higher reserve potential in Northwest Alberta and Northeast British Columbia.In Egypts Western Desert,Apaches 10.2 million gross acres encompass a sizable resource in the Cretaceous Upper Bahariya formations and outstanding exploration potential in deeper intervals from low

43、er Cretaceous to Jurassic,established producing trends.The Qasr gas/condensate field,discovered in 2003,is the largest field ever found by Apache with more than 2 trillion cubic feet of gas and 60 million barrels of estimated recoverable reserves.In Australia,we have expanded our exploration program

44、 to the high-potential Exmouth,Browse and Gippsland basins while continuing to exploit our acreage position and control of key infrastructure in the Carnarvon basin.In the Gippsland basin we actively acquired almost 1.8 million acres over the past three years and have generated a 10-well inventory o

45、f high potential exploration prospects to be drilled in 2008.Additionally,Apache and its partners are designing three development projects in the Exmouth basin that are in process of being sanctioned and approved by all parties.Apache entered the North Sea in 2003 with our acquisition of the Forties

46、 field(Forties),the largest field ever discovered in the United Kingdom.As operator,through drilling and extensive improvements to the production infrastructure,we virtually doubled production and significantly reduced per-unit operating costs from the second quarter of 2003.Our 2007 plans include i

47、nfill and extentional drilling activity at Forties to determine if we can extend the field to the west,as well as exploration drilling on acreage blocks obtained over the past couple of years.We currently have around 100 Forties field drilling locations in our inventory.For several years we held sma

48、ll interests in Argentina with the long-term view of expanding there through acquisitions.In April 2006,we purchased Pioneer Natural Resources(Pioneer)interests in Neuqun and the Austral basins for$675 million and subsequently purchased our partners,Pan American Fueguina S.R.L.(Pan American),interes

49、ts in Tierra del Fuego,gaining operatorship in the under-exploited,highly prospective Austral basin concessions.Through subsequent workovers,recompletions and development activities,we increased production on the acquired properties and have established Argentina as Apaches latest core area.While we

50、 expect unique challenges with evolving governmental regulations,we anticipate growing reserves and production in Argentina.We exited 2006 with a year-end debt-to-capitalization ratio of 22 percent despite record capital spending of$6.4 billion,excluding asset retirement costs.This flexibility enabl

51、es us to quickly act on attractive acquisition 2 transactions as they are identified,such as our agreement in January 2007 to acquire,through a joint venture interest,Permian basin assets from Anadarko Petroleum Company(Anadarko)for$1 billion.The transaction,which is subject to normal closing condit

52、ions and adjustments for matters such as preferential rights,is expected to close around the end of the first-quarter of 2007.Apache has increased reserves in each of the last 21 years and production in 27 of the last 28 years.We believe our strategy and our diversified portfolio of assets provide a

53、 platform for profitable growth through drilling and acquisitions across the cycles of our dynamic industry.In 2007,we are planning another active year of drilling.We revise our capital expenditure estimates throughout the year based on changing industry conditions and results to date.Therefore,accu

54、rately projecting annual capital spending is difficult at best.Our preliminary 2007 capital budget approaches$4.5 billion.While in most years capital budgets are expanded as the year unfolds,if commodity prices soften from year-end 2006 levels and service costs do not also decline;we plan to reduce

55、our capital spending.Regarding potential acquisitions,we continually look for properties to which we believe we can add value and earn adequate rates of return and will take advantage of those acquisition opportunities as they arise.Operating Highlights Following the sale of our interest in China in

56、 the third quarter of 2006,our interests in six countries now comprise our reportable segments:the United States,Canada,Egypt,Australia,the North Sea,and Argentina.In the U.S.,our exploration and production activities are spread between two regions:Gulf Coast and Central.The following table sets out

57、 a brief comparative summary of certain key 2006 data for each area.More detailed information regarding oil,natural gas and natural gas liquids(NGLs)production and the average sales prices received in each geographic area for 2006,2005,and 2004 is available later in this section under“Production,Pri

63、 100%1,611 1,399 The following discussions include references to our plans for 2007.These only represent initial estimates and could vary significantly from actual results.In recent years,there have been large differences between our capital expenditure forecasts and our actual activity.During the y

64、ear,we routinely adjust our level of spending based on results and changing industry conditions.United States Gulf Coast The Gulf Coast region comprises our interests in and along the Gulf of Mexico,in the areas on-and offshore Louisiana and Texas.Apache is the largest held-by-production acreage hol

65、der and the second largest producer in Gulf waters less than 1,200 feet deep.For the third year in a row,the Gulf Coast was our leading region for both production volumes and revenues.Gulf Coast activities in 2006 focused on restoring production impacted by the 2005 hurricanes,while maintaining an a

66、ctive drilling program.This region performed 296 workover and recompletion operations during 2006 and completed 65 out of 83 total wells drilled as producers.Our drilling locations mostly included proved undeveloped reserves at platforms sustaining minimum or no hurricane damage with access to third

67、-party transport facilities.In June 2006,we acquired producing properties,facilities and prospects on the Outer Continental Shelf of the Gulf of Mexico from BP plc(BP)for$845 million,adding an estimated 44.2 MMboe of proved reserves.The purchase price was allocated as follows:$747 million producing

68、properties,$42 million prospects,$56 million facilities.As of year-end 2006,the Gulf Coast region accounted for 17 percent of our estimated proved reserves.Although actual annual capital expenditures may change considerably in 2007,we currently estimate investing approximately$900 million to drill o

69、ver 90 wells and to continue our production enhancement and exploitation programs.In addition,we plan to spend an estimated$350 million on repair,redevelopment,and plugging and abandonment work required to repair damage caused by Hurricanes Katrina and Rita in 2005 that will not be covered by insura

70、nce.Central The Central Region includes assets in the Permian basin of West Texas and New Mexico,East Texas,and the Anadarko basin of western Oklahoma,where the Company got its start over 50 years ago.On January 5,2006,the Company expanded its presence in the Permian basin by purchasing an estimated

71、 31.5 MMboe of reserves in eight fields for$269 million from Amerada-Hess.In early 2007,we also entered into agreements to acquire additional Permian basin interests from Anadarko as described in more detail below under“Subsequent Events.”As of year-end 2006,the Central region accounted for approxim

72、ately 24 percent of our estimated proved reserves,the second largest concentration in the Company.During 2006,we participated in drilling 374 wells,363 of which were completed as productive.Apache performed 615 workovers and recompletions in the region during the year.We currently estimate spending

73、approximately$570 million in 2007 on drilling and production enhancement projects.Marketing In general,most of our U.S.gas is sold on a monthly basis at either monthly or daily market prices.Our natural gas is sold primarily to Local Distribution Companies(LDCs),utilities,end-users,integrated major

74、oil and gas companies and marketers.In an effort to increase sales to direct users of natural gas and to meet the needs of our customers,we also periodically sell some gas under long-term contracts at prices that fluctuate with market conditions.Approximately eight percent of our 2006 U.S.natural ga

75、s production was sold under long-term fixed-price physical contracts which expire in 2007 and 2008.See Item 7A,Quantitative and Qualitative Disclosures about Market Risk“Commodity Risk”in this Form 10-K.Apache has historically marketed and continues to sell its U.S.crude oil to integrated major oil

76、companies,purchasers,transporters,and refiners.The objective is to maximize the value of the crude oil sold by identifying the most economical markets and transportation routes available to move the crude oil via pipeline,truck or barge.Sales contracts are generally thirty(30)day evergreen contracts

77、 and renew automatically until canceled by either party.These contracts provide for sales at prices which fluctuate with daily oil market conditions,thus capturing the market value of the crude oil each day.We manage our credit risk by selling our oil to creditworthy counterparties and monitoring ou

78、r exposure on a daily basis.Canada Overview Our exploration and development activity in our Canadian region is concentrated in the Provinces of Alberta,British Columbia,Saskatchewan and to a lesser degree the Northwest Territories.The region comprises 4 24.9 percent of our estimated proved reserves,

79、the largest in the Company.We hold over 4.9 million net acres in Canada,the largest of our North American regions.Canada was our most active drilling area in 2006,with Apache participating in 874 wells,focused primarily on low-risk shallow development wells.We completed 740 as producers and conducte

80、d 274 workover and recompletion projects.Although actual annual capital expenditures may change with industry conditions and results,we currently estimate spending approximately$770 million in 2007 to drill approximately 380 wells,continue our exploitation program,albeit at a lower level,and continu

81、e developing our gas processing infrastructure.Our 2007 drilling program will include more deeper,higher risk-reward exploration wells and fewer shallow development wells.Apache is also targeting fields such as Provost and Nevis in Alberta for coalbed methane(CBM)and in the process has emerged as on

82、e of Canadas largest producers of CBM.The North and South Grant Lands obtained through farm-in agreements(discussed below)provide additional CBM potential.In 2005,Apache signed a farm-in agreement with ExxonMobil covering approximately 650,000 acres of undeveloped properties in the Western Canadian

83、province of Alberta.Under the agreement,Apache is to drill and operate 145 new wells over a 36-month period with upside potential for further drilling.ExxonMobil retains a royalty on fee lands and a convertible working interest on leasehold acreage,both of which vary dependent on activity levels.The

84、 agreement also allows Apache to test additional horizons on approximately 140,000 acres of property covered in a 2004 farm-in agreement with ExxonMobil.The 2004 farm-in agreement covered approximately 380,000 acres and stipulated drilling at least 250 wells over a two-year period beginning in Octob

85、er 2004.The 250 well commitment was met and the agreement was extended for an additional year.In 2006,Apache drilled 218 wells on the 2005 and 2004 farm-in acreage earning 93 additional acreage sections.Through the end of 2006,Apache has now drilled a total of 675 wells on the farm-in acreage from b

86、oth agreements.Marketing Our Canadian natural gas sales focuses on sales to LDCs,utilities,end-users,integrated majors,supply aggregators and marketers.Our composite client portfolio is credit worthy and diverse.Improved North American natural gas pipeline connectivity has triggered a closer correla

87、tion between Canadian and United States natural gas prices.To diversify our market exposure and optimize pricing differences in the U.S.and Canada,we transport natural gas via our firm transportation contracts to California,the Chicago area,and eastern Canada.Our objective is to sell the majority of

88、 our production monthly,either into the first of the month market,or the daily market.Over 95 percent of our Canadian natural gas production is sold on a monthly basis at either monthly or daily market prices.Approximately two percent of our sales are long-term fixed-price sales.The longest term for

89、 these sales expires in 2011.The remainder is sold under long-term commitments to Canadian aggregators and end-users where the prices we receive under these contracts fluctuate monthly with market indices.Our Canadian crude oil is primarily sold to refiners,integrated majors and marketers.To increas

90、e the market value of our condensate and heavier crudes,our condensate is either used or sold for blending purposes.We sell our crude oil and NGLs on Canadian Postings,which are market reflective prices that depend on worldwide crude oil prices and are adjusted for transportation and quality.In orde

91、r to reach more purchasers and diversify our market,we transport crude on 12 pipelines to the major trading hubs within Alberta and Saskatchewan.Egypt Overview In Egypt,our operations are conducted pursuant to production sharing contracts under which the contractor partner pays all operating and cap

92、ital expenditure costs for exploration and development.A percentage of the production,usually up to 40 percent,is available to the contractor partners to recover operating and capital expenditure costs.In general,the balance of the production is allocated between the contractor partners and the Egyp

93、tian General Petroleum Corporation(EGPC)on a contractually defined basis.Apache is the second largest acreage holder and the most active driller in the Western Desert of Egypt.Egypt is the country with our largest single acreage position where,as of December 31,2006,we held approximately 10.2 millio

94、n gross acres in 19 separate concessions.Development leases within concessions generally have a 25-year life with extensions possible for additional commercial discoveries,or on a negotiated basis.Apache is the largest producer of liquid hydrocarbons and natural gas in the Western Desert.Egypt contr

95、ibuted approximately 21 percent of Apaches production revenues and 19 percent of total production.Egypt accounted for 12 percent of total estimated proved reserves as of December 31,2006.The Company reports all estimated proved reserves held under production sharing agreements utilizing the economic

96、 interest method,which excludes the host countrys share of reserves.5 In 2006,Apache had an active drilling program in Egypt,completing 140 of 163 wells,an 86 percent success rate,and conducted 390 workovers and recompletions.We currently plan to spend approximately$1 billion in 2007.Of this,$600 mi

97、llion will be for drilling and production enhancement work.We recently received approval to expand our Western Desert gas processing capacity and infrastructure to evacuate an additional 200 MMcf/d gas volumes driven by the Qasr field discovery.We project that this upgrade will take two years to com

98、plete at a total cost of$950 million,excluding actual gas well drilling costs and we have included$350 million in our capital expenditures for 2007.On January 6,2006,the Company completed the sale of its 55 percent interest in the deepwater section of Egypts West Mediterranean Concession to Amerada

99、Hess for$413 million.Please refer to Item 7,Managements Discussion and Analysis of Financial Condition and Results of Operations“Critical Accounting Policies and Estimates,Allowance for Doubtful Accounts”in this Form 10-K for a discussion of our Egyptian receivables.Marketing We and our partners hav

100、e sold our gas production to EGPC under an Industry Pricing Formula;which is a sliding scale based on Dated-Brent crude oil with a minimum of$1.50 per MMbtu and a maximum of$2.65 per MMbtu which corresponds to a Dated-Brent price of$21.00 per barrel.Generally,the Industry Pricing Formula applies to

101、all new gas discovered and produced.In exchange for extension of the Khalda Concession lease in July 2004,Apache agreed to accept Industry Pricing on all production in excess of 100 MMcf/d,but preserved the higher price formula until 2013 on the initial 100 MMcf/d.Oil from the Khalda Concession,the

102、Qarun Concession and other nearby Western Desert blocks is either sold directly to EGPC or other third-parties.The oil sales are made either directly into the Egyptian oil pipeline grid,exported via one of two terminals on the north coast of Egypt,or sold to third parties(non-governmental)through th

103、e MIDOR refinery located in northern Egypt.Oil production that is presently sold to EGPC is sold on a spot basis at a“Western Desert”price(indexed to Brent).In 2006,we exported 28 cargoes(approximately 8.6 million barrels)of Western Desert crude oil from the El Hamra and Sidi Kerir terminals located

104、 on the northern coast of Egypt.These export cargoes were sold at market prices comparable to domestic sales to EGPC.Additionally,24 cargoes representing 3.5 million barrels were sold in Egypt to other non-governmental purchasers at prevailing market prices.Export sales from both the Khalda and Qaru

105、n areas in the Western Desert have continued in 2007.Australia Overview Our exploration activity in Australia is focused in the offshore Carnarvon,Gippsland,Browse,and Perth basins where Apache holds 6.8 million net acres in 35 Exploration Permits,10 Production Licenses,and six Retention Leases.Prod

106、uction operations are concentrated in the Carnarvon basin which is the location of all 10 Production Licenses,nine of which are operated by Apache.In 2006,the region generated$408 million of production revenues producing 15.7 MMboe(8.6 percent of our total production)and accounted for 8.8 percent of

107、 our year-end estimated proved reserves.During the year we participated in drilling 23 wells;18 exploration and five development wells.Four of the exploration wells and three of the development wells were productive for a 30 percent success rate.Exploration successes in 2006 included the Theo and We

108、st Cycad oil discoveries and the Gnu and Bambra East gas finds.The West Cycad oil discovery was drilled in the Harriet Joint Venture(HJV)area and is slated to begin production in the first quarter of 2007.The successful Theo well was drilled in the Exmouth sub-basin and is scheduled to begin product

109、ion in 2009.The Gnu well was drilled in the Reindeer/Caribou field and added significant new reserves.First production from the Reindeer/Caribou field is targeted for late 2008 or early 2009.The Bambra East well was a successful gas well in the HJV,which more than doubled the volume of gas attribute

110、d to the Bambra field area.Gas production from this asset will begin in 2007 subject to augmentation of existing infrastructure.During 2007,our Australian region plans to expand the HJV oil and gas production through development of the 2006 discoveries and drilling three additional wells:Bambra 8,Do

111、ric 2 and Lee 3.We will monitor the effects of the increased water injection at Stag and possibly drill an additional producer.We will also begin the initial phase of development drilling at the Van Gogh field.A key factor for success in 2007 will be increasing gas production and 6 reserves to fulfi

112、ll the requirements of our sales contracts,exploration success and initiating the Theo field development and final sanctions thereof.We currently estimate spending approximately$460 million in 2007 to drill 30 exploration,appraisal and development wells and another$50 million for new facilities.Mark

113、eting In 2006,we executed three new gas sales contracts in Australia.As of December 31,2006,Apache had a total of 22 active gas contracts with expiration dates ranging from April 2007 to July 2030.Generally,natural gas is sold in Western Australia under long-term,fixed-price contracts,many of which

114、contain price escalation clauses based on the Australian consumer price index.We continue to export all of our crude oil production into the international market at prices which fluctuate with world market conditions.North Sea Overview In 2006,the North Sea region generated$1.35 billion of revenue,p

115、roducing 21.5 million barrels of oil equivalent.We continued to develop our North Sea core area around the Forties field,including investments in upgrades to improve the operating efficiency of our platforms.Despite this,2006 production was down 11 percent from 2005 primarily because of production i

116、nterruptions associated with commissioning of major facility projects,and temporary shutdown of the Forties Pipeline System during the third quarter of 2006.Our focus in 2006 on infrastructure projects also displaced drilling operations needed to mitigate natural decline.In 2006,we invested$329 mill

117、ion of capital in the North Sea region,including investments on drilling,recompletion and facility upgrades.At Forties we commissioned a number of key facility projects to improve production efficiency and lower operating costs,including new power generation,a multi-platform distribution system,wate

118、r injection upgrades and drilling rig modification.Also during 2006,seismic survey data acquired over Forties in 2005 was processed for inversion to identify bypassed oil in the main reservoir units and update the inventory of future drilling targets.We also drilled one appraisal well outside Fortie

119、s,and had a second appraisal well and an exploration well in progress at the end of 2006.There were no significant additions to North Sea acreage in 2006;however,in early 2007 Apache was awarded 62,320 acres from four licenses applied for in the UK 24th Licensing Round.In block 22/6a(Bacchus),Apache

120、 increased equity from 60 percent to 70 percent and became Operator(purchasing ExxonMobils 20 percent share and farming out 10 percent).A further 652 square kilometers of 3D seismic was acquired over six blocks of our acreage.North Sea capital expenditures for 2007 are currently estimated at$480 mil

121、lion.After a year with minimal drilling,activity will significantly increase.In Forties,we will continue the development drilling program,with 15 new wells planned,and complete platform upgrades begun last year.Upgrades for 2007 include finalizing installation of additional produced water re-injecti

122、on pumps and deep gas lift compressors,and commissioning of direct fluid export from Forties Bravo to Forties Charlie.These projects will enable Forties to meet stringent new environmental targets for produced water discharge to sea as well as enhance reservoir management capabilities,and should enh

123、ance runtime efficiency.Outside Forties,four exploration and appraisal wells are scheduled to be drilled in the first half of the year.Marketing In 2006,we entered into two new term contracts for the physical sale of Forties crude at prevailing market prices,which are composed of base market indices

124、,adjusted for the higher quality of Forties crude relative to Brent and a premium to reflect the higher market value for term arrangements.Also in 2006,a new value adjustment formula(Quality Bank Adjustor)was implemented in BPs Forties Pipeline System,through which Forties crude is shipped and commi

125、ngled with crudes from other central North Sea fields.The original formula was challenged by Apache in June 2005,as it did not accurately value the Forties crude quality relative to the other crudes shipped on the Forties Pipeline System.The new agreed upon comingled stream on the formula better rep

126、resents Forties crude value and effectively increases the volume allocated to Apache from the Forties Pipeline System.7 Argentina Argentina became our newest core area following two significant acquisitions in 2006 that substantially increased our presence in the country.In the second quarter,we com

127、pleted our purchase of Pioneers operations in Argentina for$675 million with estimated proved reserves of 22 MMbbls of liquid hydrocarbons and 297 Bcf of natural gas.In the third quarter,we acquired additional interests in(and now operate)seven concessions in the Tierra del Fuego Province from Pan A

128、merican for total consideration of$429 million.Our oil and gas assets are located in the Neuqun,San Jorge and Austral basins of Argentina.In 2006,we had 9.9 MMboe of production and 110.6 MMboe of estimated proved reserves,approximately 5.4 percent and 4.8 percent,respectively,of Apaches total produc

129、tion and reserves.We plan to invest approximately$180 million drilling over 100 wells and spend an additional$60 million on production enhancement projects in 2007.Marketing In Argentina we extended our existing natural gas contracts to regulated markets through April 2007,per the Argentine Secretar

130、y of Energys request.We expect to reach a new agreement during the first-quarter of 2007 with the Argentine government,which will set the volumes to be delivered to the regulated market for the period 2007 through 2011.We also entered into four new term contracts up to two years in duration for a to

131、tal of 22 MMcf/d.These four contracts enabled Apache to lock in higher priced contracts while awaiting a new agreement to cover the internal demand of Argentina for 2007 onward.In October 2006,the Argentina government removed the export tax exempt status previously afforded the province of Tierra de

132、l Fuego through a Special Customs area exemption.The government has further assessed an export tax on all exports from Argentina based upon the price paid for natural gas imports from Bolivia.This tax reduces the value we are receiving under our contract with Methanex in Chile.We have entered into a

133、n interim agreement with Methanex to mitigate the effects of this tax and are working to reach an economically suitable final agreement.The Methanex contract represents less than 10 percent of our gas sales in Argentina.Other International China.On August 8,2006,the Company completed the sale of our

134、 24.5 percent interest in the Zhao Dong block offshore the Peoples Republic of China,to Australia-based ROC Oil Company Limited for$260 million,marking Apaches exit from China.The transaction was effective July 1,2006,and the Company recorded a gain of approximately$174 million in the third-quarter

135、of 2006.Subsequent Events On January 18,2007,the Company announced that it is acquiring controlling interest in 28 oil and gas fields in the Permian basin of West Texas from Anadarko Petroleum Corporation(Anadarko)for$1 billion.Apache estimates that these fields had proved reserves of 57 million bar

136、rels(MMbbls)of liquid hydrocarbons and 78 billion cubic feet(Bcf)of natural gas as of yearend 2006.The transaction will be effective the earlier of closing or March 31,2007.Approximately 10 percent of the Permian basin properties are subject to third-party preferential purchase rights which,if exerc

137、ised,would reduce the interests we purchase in those properties and the purchase price we would pay.The Company intends to fund the acquisition with debt.Apache and Anadarko are entering into a joint-venture arrangement to effect the transaction.In connection with the acquisition,the Company entered

138、 into cash flow hedges to protect against commodity price volatility.For the period of July 2007 through June 2010,the Company entered into hedges for a portion of both the oil and the natural gas with NYMEX based costless collars.In anticipation of closing the Anadarko transaction,we completed a pu

139、blic offering in January 2007 of$500 million of 5.625-percent notes due 2017 and$1 billion of 6.0-percent notes due 2037.The net proceeds from the offering($1.48 billion,net of original issue discounts and underwriting commissions)were used to repay a portion of our outstanding commercial paper,whic

140、h was incurred to finance acquisitions we made in 2006 and for general corporate purposes.8 Drilling Statistics Worldwide,in 2006,we participated in drilling 1,611 gross wells,with 1,399(87 percent)completed as producers.We also performed more than 1,700 workovers and recompletions during the year.H

141、istorically,our drilling activities in the U.S.generally concentrate on exploitation and extension of existing,producing fields rather than exploration.As a general matter,our operations outside of the U.S.focus on a mix of exploration and exploitation wells.In addition to our completed wells,at yea

157、nd Future Net Cash Flows As of December 31,2006,Apache had total estimated proved reserves of 1,061 MMbbls of crude oil,condensate and NGLs and 7.5 Tcf of natural gas.Combined,these total estimated proved reserves are equivalent to 2.3 billion barrels of oil equivalent or 13.9 Tcf of natural gas.Dur

158、ing 2006,the Companys reserves grew nine percent with increases in all our countries.The Companys reserves have increased for 21 consecutive years.Proved oil and gas reserves are the estimated quantities of natural gas,crude oil,condensate and NGLs that geological and engineering data demonstrate wi

159、th reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions.The Company reports all estimated proved reserves held under production sharing arrangements utilizing the“economic interest”method,which excludes the host countrys share

160、of reserves.Reserve estimates are considered proved if economical producibility is supported by either actual production or conclusive formation tests.Estimated reserves that can be produced economically through application of improved recovery techniques are included in the“proved”classification wh

161、en successful testing by a pilot project or the operation of an active,improved recovery program in the reservoir provides support for the engineering analysis on which the project or program is based.Estimated proved developed oil and gas reserves can be expected to be recovered through existing we

162、lls with existing equipment and operating methods.Apache emphasizes that its reported reserves are estimates which,by their nature,are subject to revision.The estimates are made using available geological and reservoir data,as well as production performance data.These estimates are reviewed througho

163、ut the year,and revised either upward or downward,as warranted by additional performance data.Apaches proved reserves are estimated at the property level and compiled for reporting purposes by a centralized group of experienced reservoir engineers who are independent of the operating groups.These en

164、gineers interact with engineering and geoscience personnel in each of Apaches operating areas,and with accounting and marketing employees to obtain the necessary data for projecting future production,costs,net revenues and ultimate recoverable reserves.Reserves are reviewed internally with senior ma

165、nagement and presented to Apaches Board of Directors in summary form on a quarterly basis.Annually,each property is reviewed in detail by our centralized and operating region engineers to ensure forecasts of operating expenses,netback prices,production trends and development timing are reasonable.11

182、 Liquids,Which Have Historically Been Very Volatile Our estimated proved reserves,revenues,profitability,operating cash flows and future rate of growth are highly dependent on the prices of crude oil,natural gas and NGLs,which are affected by numerous factors beyond our control.Historically,these pr

183、ices have been very volatile.A significant downward trend in commodity prices would have a material adverse effect on our revenues,profitability and cash flow,and could result in a reduction in the carrying value of our oil and gas properties and the amounts of our estimated proved oil and gas reser

184、ves.Our Commodity Hedging May Prevent Us From Benefiting Fully From Price Increases and May Expose Us to Other Risks To the extent that we engage in hedging activities to protect ourselves from commodity price volatility,we may be prevented from realizing the benefits of price increases above the le

185、vels of the hedges.Acquisitions or Discoveries of Additional Reserves are Needed to Avoid a Material Decline in Reserves and Production The rate of production from oil and gas properties generally declines as reserves are depleted.Except to the extent that we find or acquire additional properties co

186、ntaining estimated proved reserves,conduct successful exploration and development activities or,through engineering studies,identify additional behind-pipe zones,secondary recovery reserves or tertiary recovery reserves,our estimated proved reserves will decline materially as reserves are produced.F

187、uture oil and gas production is,therefore,highly dependent upon our level of success in acquiring or finding additional reserves.Our Drilling Activities May Not Be Productive Drilling for oil and gas involves numerous risks,including the risk that we will not encounter commercially productive oil or

188、 gas reservoirs.The costs of drilling,completing and operating wells are often uncertain,and drilling operations may be curtailed,delayed or canceled as a result of a variety of factors including,but not limited to:Certain future drilling activities may not be successful and,if unsuccessful,this fai

189、lure could have an adverse effect on our future results of operations and financial condition.While all drilling,whether developmental or exploratory,involves these risks,exploratory drilling involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons.Risks Arising F

190、rom the Failure to Fully Identify Potential Problems Related to Acquired Reserves or to Properly Estimate Those Reserves One of our primary growth strategies is the acquisition of oil and gas properties.Although we perform a review of the acquired properties that we believe is consistent with indust

191、ry practices,such reviews are inherently incomplete.It generally is not feasible to review in depth every individual property involved in each acquisition.Ordinarily,we will focus our review efforts on the higher-value properties and will sample the remainder.However,even a detailed review of record

192、s and properties may not necessarily reveal existing or potential problems,nor will it 13 unexpected drilling conditions;pressure or irregularities in formations;equipment failures or accidents;fires,explosions,blowouts and surface cratering;marine risks such as capsizing,collisions and hurricanes;o

193、ther adverse weather conditions;and shortages or delays in the delivery of equipment.permit a buyer to become sufficiently familiar with the properties to assess fully their deficiencies and potential.Inspections may not always be performed on every well,and environmental problems,such as ground wat

194、er contamination,are not necessarily observable even when an inspection is undertaken.Even when problems are identified,we often assume certain environmental and other risks and liabilities in connection with acquired properties.There are numerous uncertainties inherent in estimating quantities of p

195、roved oil and gas reserves and actual future production rates and associated costs with respect to acquired properties,and actual results may vary substantially from those assumed in the estimates.In addition,there can be no assurance that acquisitions will not have an adverse effect upon our operat

196、ing results,particularly during the periods in which the operations of acquired businesses are being integrated into our ongoing operations.We Are Subject to Governmental Risks That May Impact Our Operations Our operations have been,and at times in the future may be,affected by political development

197、s and by federal,state,provincial and local laws and regulations such as restrictions on production,changes in taxes,royalties and other amounts payable to governments or governmental agencies,price controls and environmental protection laws and regulations.Global Political and Economic Developments

198、 May Impact Our Operations Political and economic factors in international markets may have a material adverse effect on our operations.On an equivalent-barrel basis,approximately 63 percent of our oil,NGLs and natural gas production in 2006 was outside the United States,and approximately 59 percent

199、 of our estimated proved oil and gas reserves on December 31,2006 were located outside of the United States.There are many risks associated with operations in international markets,including changes in foreign governmental policies relating to crude oil,NGLs,and natural gas pricing and taxation,othe

200、r political,economic or diplomatic developments,changing political conditions and international monetary fluctuations.These risks include:political and economic instability or war;the possibility that a foreign government may seize our property with or without compensation;confiscatory taxation;lega

201、l proceedings and claims arising from our foreign investments or operations;a foreign government attempting to renegotiate or revoke existing contractual arrangements,or failing to extend or renew such arrangements;fluctuating currency values and currency controls;and constrained natural gas markets

202、 dependent on demand in a single or limited geographical area.On December 23,2004,Apache entered into a 20-year insurance contract with the Overseas Private Investment Corporation(OPIC)which provides$300 million of political risk insurance for the Companys Egyptian operations.This policy insures us

203、against(1)non-payment by EGPC of arbitral awards covering amounts owed Apache on past due invoices and(2)expropriation of exportable petroleum when actions taken by the Government of Egypt prevent Apache from exporting our share of production.See Item 7,Managements Discussion and Analysis of Financi

204、al Condition and Results of Operations,“Critical Accounting Policies and Estimates,Allowance for Doubtful Accounts”in this Form 10-K for additional discussion of our Egyptian receivables.In addition to the contract with OPIC,the Company has acquired commercial political risk insurance covering signi

205、ficant portions of its investments in Egypt and Argentina.The insurance provides coverage for confiscation,nationalization,and expropriation risks and currency inconvertibility,and is written on multi-year contracts with highly rated international insurers.Actions of the United States government thr

206、ough tax and other legislation,executive order and commercial restrictions can adversely affect our operating profitability in the U.S.as well as other countries.Various agencies of the United States and other governments have,from time to time,imposed restrictions which have limited our ability to

207、gain attractive opportunities or even operate in various countries.These restrictions have in the past limited our foreign opportunities and may continue to do so in the future.14 Weather and Climate May Have a Significant Impact on Our Revenues and Productivity Demand for oil and natural gas are,to

208、 a significant degree,dependent on weather and climate,which impacts the price we receive for the commodities we produce.In addition,our exploration and development activities and equipment can be adversely affected by severe weather,such as hurricanes in the Gulf of Mexico,which may cause a loss of

209、 production from temporary cessation of activity or lost or damaged equipment.While our planning for normal climatic variation,insurance program,and emergency recovery plans mitigate the effects of the weather,not all such effects can be predicted,eliminated or insured against.Costs Incurred Related

210、 to Environmental Matters We,as an owner or lessee and operator of oil and gas properties,are subject to various federal,provincial,state,local and foreign country laws and regulations relating to discharge of materials into,and protection of the environment.These laws and regulations may,among othe

211、r things,impose liability on the lessee under an oil and gas lease for the cost of pollution clean-up resulting from operations,subject the lessee to liability for pollution damages,and require suspension or cessation of operations in affected areas.We have made and will continue to make expenditure

212、s in our efforts to comply with these requirements,which we believe are necessary business costs in the oil and gas industry.We have established policies for continuing compliance with environmental laws and regulations,including regulations applicable to our operations in all countries in which we

213、do business.We also have established operational procedures and training programs designed to minimize the environmental impact of our field facilities.The costs incurred by these policies and procedures are inextricably connected to normal operating expenses such that we are unable to separate the

214、expenses related to environmental matters;however,we do not believe any such additional expenses are material to our financial position or results of operations.Apache manages its exposure to environmental liabilities on properties to be acquired by identifying existing problems and assessing the po

215、tential liability.The Company also conducts periodic reviews,on a company-wide basis,to identify changes in its environmental risk profile.These reviews evaluate whether there is a probable liability,its amount,and the likelihood that the liability will be incurred.The amount of any potential liabil

216、ity is determined by considering,among other matters,incremental direct costs of any likely remediation and the proportionate cost of our employees who are expected to devote a significant amount of time to any possible remediation effort.Our general policy is to limit any reserve additions to incid

217、ents or sites that are considered probable to result in an expected remediation cost exceeding$100,000.We maintain insurance coverage,which we believe is customary in the industry,although we are not fully insured against all environmental risks.As described in Note 10,Commitments and Contingencies

218、of Item 15,in this Form 10-K,on December 31,2006,we had an accrued liability of$17 million for environmental remediation.We have not incurred any material environmental remediation costs in any of the periods presented and we are not aware of any future environmental remediation matters that would b

219、e material to our financial position or results of operations.Although environmental requirements have a substantial impact upon the energy industry,generally these requirements do not appear to affect us any differently,or to any greater or lesser extent,than other upstream companies in the industr

220、y.We do not believe that compliance with federal,provincial,state,local or foreign country provisions regulating the discharge of materials into the environment,or otherwise relating to the protection of the environment,will have a material adverse effect upon the capital expenditures,earnings or co

221、mpetitive position of Apache or its subsidiaries;however,there is no assurance that changes in or additions to laws or regulations regarding the protection of the environment will not have such an impact.Industry Competition Strong competition exists in all sectors of the oil and gas exploration and

222、 production industry.We compete with major integrated and other independent oil and gas companies for acquisition of oil and gas leases,properties and reserves,equipment and labor required to explore,develop and operate those properties and the marketing of oil and natural gas production.Higher rece

223、nt crude oil and natural gas prices have increased the costs of properties 15 available for acquisition and there are a greater number of companies with the financial resources to pursue acquisition opportunities.Many of our competitors have financial and other resources substantially larger than th

224、ose we possess and have established strategic long-term positions and maintain strong governmental relationships in countries in which we may seek new entry.As a consequence,we may be at a competitive disadvantage in bidding for drilling rights.In addition,many of our larger competitors may have a c

225、ompetitive advantage when responding to factors that affect demand for oil and natural gas production,such as changing worldwide prices and levels of production,the cost and availability of alternative fuels and the application of government regulations.We also compete in attracting and retaining pe

226、rsonnel,including geologists,geo-physicists,engineers and other specialists.Insurance Does Not Cover All Risks Exploration for and production of oil and natural gas can be hazardous,involving unforeseen occurrences such as blowouts,cratering,fires and loss of well control,which can result in damage

227、to or destruction of wells or production facilities,injury to persons,loss of life,or damage to property or the environment.We maintain insurance against certain losses or liabilities arising from our operations in accordance with customary industry practices and in amounts that management believes

228、to be prudent;however,insurance is not available to us against all operational risks.In response to large underwriting losses caused by Hurricanes Katrina and Rita,the insurance industry has reduced capacity for windstorm damage and substantially increased premium rates.As a result,there is no assur

229、ance that Apache will be able to arrange insurance to cover fully its Gulf of Mexico exposures at a reasonable cost when the current policies expire.As of December 31,2006,we did not have any unresolved comments from the SEC staff that were received 180 or more days prior to yearend.We responded to

230、comments from the SEC staff that we received in December 2006,and are awaiting final resolution.We do not believe the comments or our responses thereto materially impact any previous or prospective disclosures.See the information set forth in Note 10,Commitments and Contingencies of Item 15 and Item

246、ts of Item 15 in this Form 10-K.For a discussion of significant acquisitions and divestitures,see Note 2 of Item 15 in this Form 10-K.Overview Apache Corporation(Apache or the Company)is an independent energy company whose principle business includes exploration,development and production of crude o

247、il,natural gas and natural gas liquids.We operate in six countries:the United States,Canada,Egypt,Australia,offshore the United Kingdom in the North Sea,and Argentina.In 2006,we earned$2.5 billion,within three percent of last years record earnings,despite a 19 percent decline in gas price realizatio

248、ns.Cash provided by operating activities totaled$4.3 billion,flat to 2005.We also set records for production and reserves with worldwide equivalent production increasing 10 percent,making 2006 the 27th out of the last 28 years that we have reported production growth.Reserves grew nine percent,increa

249、sing in every core area,marking the 21st consecutive year of reserve growth at Apache.Our growth strategy focuses on economic growth through drilling,acquisitions,or a combination of both,depending on,among other things,costs levels,potential rates of return and the availability of acquisition oppor

250、tunities.We utilize a portfolio approach to provide diversity in terms of geologic risk,geographic location,hydrocarbon mix(crude oil and natural gas)and reserve life.This strategy provides multiple avenues for growth.We took several steps in 2006 to balance and grow our asset base.Outside of North

251、America,we divested two assets:the undeveloped deepwater section of Egypts West Mediterranean Concession and our interest in the Zhao Dong block offshore the Peoples Republic of China.To rebalance our international portfolio,we bolstered our position in Argentina purchasing an estimated 109 MMboe of

252、 reserves in two separate transactions.After increasing our production on these properties through active operations,Argentina is now our newest core area and we operate an 19 ITEM 6.SELECTED FINANCIAL DATA As of or For the Year Ended December 31,2006 2005 2004 2003 2002 (In thousands,except per sha

256、 Permian basin and Gulf of Mexico positions.In January 2006,we purchased an estimated 31 MMboe of proved reserves in long life producing properties in the Permian basin of West Texas.The acquisition was balanced by purchasing 44 MMboe of shorter life,but higher rate-of-return reserves in the Gulf of

257、 Mexico.Worldwide,we purchased an estimated 196.5 MMboe of proved reserves.On the exploration and development side,we drilled 1,611 wells with an 87 percent success rate with active drilling programs in all core areas.We invested$3.7 billion in exploration and development activities,excluding asset

258、retirement costs and capitalized interest,adding 224 MMboe in of estimated proved reserves.Our reserve life across our core areas spans from eight to twenty years,with a 46 percent oil and 54 percent natural gas mix,consistent with yearend 2005.Apaches profitability is a function of commodity prices

259、,the cost to add reserves through drilling and acquisitions and the cost to produce our reserves.Trends in commodity prices directly impact oil and gas revenues and demand for services and thus,have a significant impact on drilling and operating costs.We closely monitor trends in drilling costs in e

260、ach of our core areas and the prices paid to acquire producing properties and,when appropriate,adjust our capital budgets.Commodity prices are driven by the prevailing worldwide price for crude oil,spot prices applicable to our United States and Canadian natural gas production and many other factors

261、 beyond our control.Historically,these prices have been volatile and unpredictable,and 2006 was no exception.Our 2006 crude oil price realizations averaged$59.92 per barrel,up 16 percent from 2005,ranging from an average monthly high of$68.59 per barrel in July to a low of$52.64 per barrel in Octobe

262、r as demand waned in the U.S.with a delay in the onset of seasonal temperatures.Natural gas realizations were 19 percent lower than last year,averaging$5.17 per thousand cubic feet(Mcf),with a high of$8.05 per Mcf in January,and a low of$3.85 per Mcf in October.A high drilling and operating cost env

263、ironment once again challenged us in 2006,continuing the trend seen over the past few years.This upward trend is a reflection of increased demand driven by historically high commodity prices.In addition,repair activity from the 2005 Gulf of Mexico hurricanes also increased demand for services in the

264、 U.S.,and accordingly,costs.Cost increases were reflected in nearly all of our drilling and lease operating cost components,including:rig rates,drill pipe costs,labor costs,chemical costs and the costs of power and fuel.The Company reviews costs for each core area on a routine basis and pursues alte

265、rnatives in maintaining efficient levels of costs and expenses.Despite pressure from rising costs,2006 margins,while down slightly from record 2005 levels,were the second highest in our 50-plus-year history.For purposes of this discussion,margins are calculated as follows:While the Company has made

266、considerable progress recovering from the damage caused by Hurricanes Katrina and Rita,which struck in late August and late September 2005,the hurricanes had considerable impact on both 2006 and 2005 operations and results,and will impact 2007 operations.In addition to extensive damage to Apaches on

267、shore and offshore Gulf of Mexico production and transportation facilities,third-party pipelines,terminals and processing facilities,which the Company relies upon to transport and process its crude oil and natural gas also sustained substantial damage.For a discussion of the impact on 2006 and 2005

280、plc(BP)on the Outer Continental Shelf of the Gulf of Mexico.The original purchase price was reduced from$1.3 billion for 18 producing fields to$845 million because other interest owners exercised their preferential rights to purchase five of the 18 fields.The purchase price consisted of$747 million

281、of proved property,$42 million of unproved property and$56 million of facilities.The settlement price on the date of closing of$821 million was adjusted primarily for revenues and expenditures occurring between the April 1,2006 effective date and the closing date of the acquisition.The acquired prop

282、erties include 13 producing fields(nine of which are operated)with estimated proved reserves of 19.5 MMbbls of liquid hydrocarbons and 148 Bcf of natural gas.Apache financed the purchase with cash on hand and commercial paper.Pending Acquisition U.S.Permian Basin On January 18,2007,the Company annou

283、nced that it is acquiring controlling interest in 28 oil and gas fields in the Permian basin of West Texas from Anadarko Petroleum Corporation(Anadarko)for$1 billion.Apache estimates that these fields had proved reserves of 57 million barrels(MMbbls)of liquid hydrocarbons and 78 billion cubic feet(B

284、cf)of natural gas as of yearend 2006.The transaction will be effective the earlier of closing or March 31,2007.Approximately 10 percent of the Permian basin properties are subject to third-party preferential purchase rights which,if exercised,would reduce the interests we purchase in those propertie

285、s and the purchase price we would pay.The Company intends to fund the acquisition with debt.Apache and Anadarko are entering into a joint-venture arrangement to effect the transaction.In connection with the acquisition,the Company entered into cash flow hedges to protect against commodity price vola

286、tility.For the period of July 2007 through June 2010,the Company entered into hedges for a portion of both the oil and the natural gas with NYMEX based costless collars.2006 Divestitures On January 6,2006,the Company completed the sale of its 55 percent interest in the deepwater section of Egypts We

287、st Mediterranean Concession to Amerada Hess for$413 million.Apache did not have any proved reserves booked for these properties.On August 8,2006,the Company completed the sale of its 24.5 percent interest in the Zhao Dong block offshore,the Peoples Republic of China,to Australia-based ROC Oil Compan

288、y Limited for$260 million,marking Apaches exit from China.The effective date of the transaction was July 1,2006.The Company recorded a gain of$174 million in the third quarter of 2006.2005 Acquisitions In May 2005,Apache signed a farm-in agreement with Exxon Mobil Corporation(ExxonMobil)covering app

289、roximately 650,000 acres of undeveloped properties in the Western Canadian province of Alberta.Under the agreement,Apache is to drill and operate 145 new wells over a 36-month period with upside potential for further drilling.ExxonMobil will retain a royalty on fee lands and a convertible working in

290、terest on leasehold acreage.The agreement also allows Apache to test additional horizons on approximately 140,000 acres of property covered in a 2004 farm-in agreement with ExxonMobil.Revenues Our revenues are sensitive to changes in prices received for our products.A substantial portion of our prod

291、uction is sold at prevailing market prices which fluctuate in response to many factors that are outside of our control.Given the current tightly balanced supply-demand market,small variations in either supply or demand,or both,can have dramatic effects on prices we receive for our oil and natural ga

292、s production.Political instability and availability of alternative fuels could impact worldwide supply,while other economic factors could impact demand.22 Oil and Natural Gas Prices While the market price received for crude oil and natural gas varies among geographic areas,crude oil trades in a worl

293、dwide market,whereas natural gas,which has a limited global transportation system,is subject to local supply and demand conditions.Consequently,price movements for all types and grades of crude oil generally move in the same direction,while natural gas price movements generally follow local market c

294、onditions.Apache primarily sells its natural gas into four markets:For specific marketing arrangements by segment,please refer to Item 1 and 2.Business and Properties of this Form 10-K.23 1)North America,which has a common market and where supply and demand are currently tightly balanced,creating a

295、volatile pricing environment;2)Australia,which has a local market with mostly fixed-price contracts;3)Egypt,which has a local market where the price received for our production is indexed to a weighted-average Dated-Brent crude oil price;most of which is subject to a ceiling of$2.65 per MMBtu at oil

296、-prices of$21 per barrel or above;and 4)Argentina,where the price we receive on a portion of our natural gas production is regulated by the government,at prices from$.38 to$1.40 per MMBtu.The volumes we are required to sell at regulated prices are set by the government and vary with seasonal factors

303、erves,a consequence of geographic diversification is a shifting geographic mix of our oil revenues and natural gas revenues.For the reasons discussed in the Oil and Natural Gas Prices section above,contributions to oil revenues and gas revenues should be viewed separately.The following table present

304、s each segments oil revenues and gas revenues as a percentage of total oil revenues and gas revenues,respectively.Crude Oil Contribution In 2006,oil revenue contributions outside of North America were 64 percent of our total consolidated oil revenues,equal to 2005 contributions.Except for Australia,

305、all core regions saw oil revenue growth in 2006 when compared to 2005.Egypt and the United States saw their contributions rise as their 2006 revenue gains,relative to 2005,outpaced gains in our other regions,benefiting from both higher relative oil prices and production.Argentinas contribution incre

306、ase in 2006,compared to 2005,was virtually all attributable to the 2006 acquisitions discussed above,although the region also benefited from price improvement.The North Sea and Canadas 2006 contributions fell because higher prices were somewhat neutralized by lower relative production and higher oil

307、 revenue in other core areas.In 2005,oil revenue contributions from outside the U.S.rose six percent to 74 percent of our total consolidated oil revenues.Production growth and significantly higher price realizations drove the North Seas oil revenue contributions to 29 percent of consolidated oil rev

308、enues from 16 percent the prior year and were largely responsible for the growth of non-U.S.oil revenues.U.S.oil revenues made up 26 percent of 2005 oil revenues,down six percent from 2004,a consequence of the 2005 hurricane activity and the significant growth in North Sea production.Australias cont

309、ribution to 2005 consolidated oil revenues fell to seven percent from 13 percent on a 39 percent decrease in production compared to 2004.Crude Oil Revenues Crude oil revenues in 2006 increased$498 million from 2005 to$4.9 billion.Price gains across all regions,which averaged$8.26 more per barrel tha

310、n 2005,generated an additional$706 million of revenues.These additional revenues were partially offset by the effect on revenues from a four percent decline in production.All segments reported a significant increase in realized crude oil price,with Argentina,Egypt,and the U.S.also benefiting from pr

311、oduction growth compared to 2005.Egypt generated an additional$233 million of crude oil revenue in 2006 when compared to 2005.An 18 percent increase in crude oil price realizations,generated$200 million of the additional revenues,with the remainder coming from a three percent increase in production.

312、While Egypt experienced production growth in many areas,the predominate contributor was the Khalda Concession which benefited from a full year of associated condensate related to increased Qasr field gas production.25 Oil Revenues Gas Revenues For the Year Ended December 31,For the Year Ended Decemb

314、$162 million compared to 2005,with a 13 percent increase in crude oil price realizations contributing$151 million of the additional revenues.A small increase in 2006 oil production,relative to 2005,contributed the remaining$11 million.The third-quarter 2005 hurricanes reduced Apaches 2006 average an

315、nual daily crude oil production 13,100 barrels per day(b/d),compared to 10,813 b/d in 2005.Shut-in production reduced the Companys 2006 and 2005 crude oil revenues by approximately$297 million and$186 million,respectively.Central region production rose 18 percent,reflecting drilling and recompletion

316、 activity in the Permian basin and Southeast New Mexico,and the Amerada Hess acquired properties.Gulf Coast production was 10 percent below 2005 levels with downtime,hurricane production shut-ins and natural decline outpacing growth attributed to drilling and recompletion activity and the BP acquire

317、d properties.The Gulf Coast regions fourth-quarter 2006 production averaged 43,995 b/d compared to 23,487 b/d in the comparable 2005 quarter,a testament to the progress in returning hurricane damaged properties to production during 2006,as well as the benefit of the BP acquired properties.Argentinas

318、 2006 oil revenues increased$91 million over 2005 with$89 million of the increase associated with production growth,driven primarily by acquired properties and subsequent exploitation activities.Higher oil price realizations generated the other$2 million.The North Seas 2006 crude oil revenues were$8

319、0 million higher than 2005 with$240 million of additional revenues generated from a 19 percent increase in price realizations,partially offset by lower production,which was down 11 percent on a comparative basis.Production was lower in 2006 primarily because of production interruptions associated wi

320、th commissioning of major infrastructure projects and temporary unplanned shutdown of the third-party Forties Pipeline System during the third quarter of 2006.The focus in 2006 on upgrades also displaced drilling operations necessary to mitigate natural decline.Canadas 2006 oil revenues increased$17

321、 million over 2005,with$56 million of additional revenues associated with higher price realizations,partially offset by lower production,which was down eight percent.Canada production was down in most areas as natural decline exceeded drilling and production enhancement activities.Australias 2006 cr

322、ude oil revenues were$27 million less than 2005,reflecting a 23 percent decline in production and an 18 percent increase in realized price.The production decrease resulted from normal field decline which offset a full year of associated condensate production from the John Brookes field and other dev

323、elopment activities,mainly in the Bambra,Zephyrus and Stag areas.Chinas 2006 oil revenues were$59 million less than 2005,a consequence of the August 2006 divestiture.Apache manages a small portion of its exposure to fluctuations in crude oil prices using financial derivatives.Approximately nine perc

324、ent of our worldwide crude oil production was subject to financial derivative hedges in 2006,compared to six percent in 2005.(See Note 3,Hedging and Derivative Instruments,of this Form 10-K for a summary of the current derivative positions and terms.)These financial derivative instruments reduced ou

326、roduction growth.However,these incremental production revenues were all but eliminated by the effect of lower prices,especially in our North American regions,where prices are typically higher,but more volatile,than our other regions.Revenues in the U.S.and Canada dropped in 2006 on a comparative bas

327、is,while all other core gas producing regions experienced an increase in revenue.Egypts contribution to 2006 consolidated gas revenues rose three percent in 2006,compared to 2005,while Australias contribution increased one percent.Argentina contributed one percent of consolidated gas revenues.In 200

328、5,88 percent of Apaches natural gas revenues came from North America,54 percent from the U.S.and 34 percent from Canada.The U.S.contribution decreased four percent from 2004,primarily because of production declines,the impact Hurricanes Katrina and Rita had on U.S.Gulf of Mexico revenues,and the add

329、itional revenues generated by Canada and Egypt.Our U.S.Gulf Coast region,which contributed 63 percent of Apaches U.S.2005 26 production,down six percent from 2004,is characterized by reservoirs which demonstrate high initial production rates followed by steep declines when compared to most other U.S

330、.producing areas.Canadas contribution was up five percent from 2004 resulting from 14 percent production growth and higher price gains,relative to other areas.Egypts contribution to total gas revenues decreased slightly to nine percent from 10 percent in 2004.Australias contribution to 2005 natural

331、gas revenues remained the same as 2004 at three percent.Natural Gas Revenues Our 2006 consolidated natural gas revenues increased$73 million from the prior year with$614 million of additional revenues generated from production growth mostly offset by the effect of a 19 percent decline in realized pr

332、ices.All core gas producing regions generated additional revenues in 2006 from production growth;however they were mostly offset by lower relative natural gas prices.Egypt contributed$73 million more to 2006 consolidated natural gas revenues compared to 2005 on a 31 percent increase in production an

333、d a four percent decrease in realized gas prices.The year-over-year production growth came primarily from the Khalda concession,mostly attributable to a full year of production from the Qasr field.Argentinas 2006 natural gas revenues increased$38 million compared to 2005,with all of the additional revenues associated with production growth.As with oil,the production growth primarily came from acqu
