                                   (UNAUDITED)


     These financial statements have been prepared by Apache Corporation (Apache
or the Company) without audit, pursuant to the rules and regulations of the
Securities and Exchange Commission, and reflect all adjustments which are, in
the opinion of management, necessary for a fair statement of the results for the
interim periods, on a basis consistent with the annual audited financial
statements. All such adjustments are of a normal recurring nature. Certain
information, accounting policies, and footnote disclosures normally included in
financial statements prepared in accordance with accounting principles generally
accepted in the United States have been omitted pursuant to such rules and
regulations, although the Company believes that the disclosures are adequate to
make the information presented not misleading. These financial statements should
be read in conjunction with the financial statements and the summary of
significant accounting policies and notes thereto included in the Company's most
recent annual report on Form 10-K.

     On December 18, 2002, the Company declared a five percent stock dividend
payable on April 2, 2003, to shareholders of record on March 12, 2003. Quarterly
share and per share information for 2002 have been restated to reflect this
stock dividend.

1.   ACQUISITIONS

     On January 13, 2003, Apache announced that it had entered into agreements
to purchase producing properties in the North Sea and Gulf of Mexico from
subsidiaries of BP p.l.c. (referred to collectively as "BP") for $1.3 billion,
with $670 million allocated to the Gulf of Mexico properties and $630 million
allocated to properties in the North Sea. The properties included estimated
proved reserves of 233.2 million barrels of oil equivalent (MMboe), 147.6 MMboe
located in the North Sea with the balance in the Gulf of Mexico. Both purchase
agreements were effective as of January 1, 2003. As is customary, Apache assumed
BP's abandonment obligation for the properties, which was considered in
determining the purchase price. Both the Gulf of Mexico and North Sea assets
acquired from BP were funded with net proceeds of approximately $554 million
from the issuance of 9.9 million shares of common stock in January 2003, and
proceeds from additional debt of approximately $604 million borrowed under
existing lines of credit and commercial paper.

     Apache and BP closed the above referenced acquisition of the Gulf of Mexico
properties on March 13, 2003, which included BP's interest in 56 producing
fields, and 104 blocks. At closing, the $670 million purchase price was adjusted
for normal closing items and preferential rights exercised by third parties. The
exercise of preferential rights by third parties reduced the purchase price by
$73 million and estimated reserves by 9.6 MMboe. The purchase price was further
adjusted for various normal closing items, including revenues and expenditures
related to the properties for the period between the effective and closing
dates. As a result, cash consideration of $509 million was paid by Apache upon
closing. In a separate transaction closed February 21, 2003, Apache purchased
BP's interest in several other Gulf of Mexico properties with estimated proved
reserves of 2.1 MMboe for an adjusted purchase price of $15 million. Including
$4 million of transaction costs, total cash consideration for the two
acquisitions of Gulf of Mexico properties from BP totaled $528 million.

     The acquisition of the U.K. North Sea properties closed on April 2, 2003,
at which time Apache paid a purchase price, adjusted for normal closing and
working capital adjustments, of $630 million. The acquisition of the North Sea
properties includes a 96 percent interest in the Forties Field and establishes a
new core area for the Company. In conjunction with the Forties acquisition,
Apache may be required to issue a letter of credit to BP to cover the present
value of related asset retirement obligations if the rating of the Company's
senior unsecured debt is lowered by both Moody's and Standard and Poor's from
its current ratings of A3 and A-, respectively. Should this occur, the initial
letter of credit amount would be 175 million British pounds. Apache has agreed
to sell all of the North Sea production from those properties over the next two
years to BP at a combination of fixed and market sensitive prices pursuant to a
contract entered into in connection with the North Sea purchase agreement.

     On July 3, 2003, Apache announced that it had completed the acquisition of
producing properties on the Outer Continental Shelf of the Gulf of Mexico from
Shell Exploration and Production Company (Shell) for $200 million, subject to
normal post-closing adjustments, including preferential rights. Prior to the
transaction, Morgan Stanley Capital Group, Inc. (Morgan Stanley) paid Shell $300
million to acquire an overriding royalty interest in a portion of the reserves
to be produced over the next four years. Shell's sale of an overriding royalty
interest to Morgan Stanley is commonly known in the industry as a volumetric
production payment (VPP). Under the terms of the VPP, Morgan Stanley is to
receive a fixed volume of oil and gas production over approximately four years
beginning in August 2003 for gas and November 2003 for oil. The VPP reserves and
production will not be recorded by Apache.

     Apache will record estimated proved reserves of 124.6 billion cubic feet
(Bcf) of natural gas and 6.6 million barrels of oil. In addition, a $60 million
liability for the future cost to produce and deliver volumes subject to the VPP
will be recorded by the Company because the overriding royalties are not
burdened by production costs. This liability will be amortized as the volumes
are produced and delivered to Morgan Stanley. The purchase agreement was
effective as of July 1, 2003. The acquisition included interests in 26 fields
covering 50 blocks (approximately 209,000 acres) and interests in two onshore
gas plants. Apache will operate 15 of the fields with 91 percent of the
production. The purchase price was funded by borrowings under the Company's
lines of credit and commercial paper program.

2.    DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

     Apache uses a variety of strategies to manage its exposure to fluctuations
in commodity prices. As established by the Company's hedging policy, Apache
primarily enters into cash flow hedges in connection with selected acquisitions
to protect against commodity price volatility. The success of these acquisitions
is significantly


                                       7



influenced by Apache's ability to achieve targeted production at forecasted
prices. These hedges effectively reduce price risk on a portion of the
production from the acquisitions.

     During the first quarter of 2003, in conjunction with the acquisitions from
BP and during the fourth quarter of 2002, in conjunction with the South
Louisiana properties acquisition, Apache entered into, and designated as cash
flow hedges, natural gas and crude oil fixed-price swaps and natural gas option
collars. These positions were entered into in accordance with the Company's
hedging policy and involved several counterparties which are rated A+ or better.
As of September 30, 2003, the outstanding positions of our cash flow hedges were
as follows:

     In addition to the fixed-price swaps and option collars, Apache entered
into a separate crude oil physical sales contract with BP. The sales contract is
a normal purchase and sale under Statement of Financial Accounting Standards
(SFAS) No. 133 and, therefore, the Company has designated and accounted for the
contract under the accrual method. As of September 30, 2003, the outstanding
terms of the contract were as follows:

     Based on current market prices, the Company recorded an unrealized loss in
other comprehensive income of $34.8 million ($21.7 million after tax). Any loss
will be realized in future earnings contemporaneously with the related sales of
natural gas and crude oil production applicable to specific hedges. Were current
prices to hold, a loss of $22.8 million ($14.2 million after tax) would be
realized over the next 12 months. However, these amounts could vary materially
as a result of changes in market conditions. The contracts designated as hedges
qualified and continue to qualify for hedge accounting in accordance with SFAS
No. 133, as amended.

3.   DEBT

     On May 15, 2003, Apache Finance Canada Corporation (Apache Finance Canada)
issued $350 million of 4.375 percent, 12-year, senior unsecured notes in a
private placement. The notes are irrevocably and unconditionally guaranteed by
Apache. Interest is payable semi-annually on May 15 and November 15 of each year
commencing on November 15, 2003. The notes were sold pursuant to Rule 144A and
Regulation S, and may not be offered or sold in the United States absent
registration or an applicable exemption from the registration requirements of
the Securities Act of 1933, as amended.

     If changes in relevant tax laws occur that would require Apache Finance
Canada to pay additional amounts under the terms of the indenture, Apache
Finance Canada has the right to redeem the notes prior to maturity. In addition,
the notes are redeemable, as a whole or in part, at Apache Finance Canada's
option, subject to a make-whole premium. The proceeds were used to reduce bank
debt and outstanding commercial paper and for general corporate purposes.

4.       PREFERRED INTERESTS OF SUBSIDIARIES

     On September 26, 2003, Apache repurchased and retired preferred interests
issued by three of its subsidiaries for approximately $443 million, plus an
additional $1 million for accrued dividends and distributions. The transactions
involved the purchase of preferred stock issued by two of the Company's
subsidiaries for approximately $82 million and the retirement of a limited
partnership interest in a partnership controlled by a subsidiary of the Company
for approximately $361 million. Apache funded the transactions with available
cash on hand and by issuing commercial paper under its existing commercial paper
facility.

5.       CAPITAL STOCK

     On January 22, 2003, the Company completed a public offering of 9.9 million
shares of Apache common stock, adjusted for the five percent common stock
dividend, including underwriters' over-allotment option, for net proceeds of
approximately $554 million. The proceeds were used to purchase producing
properties in the North Sea and the Gulf of Mexico from BP.

     On September 12, 2003, the Company announced that its Board of Directors
voted to increase the quarterly cash dividend on its common stock to 12 cents
per share from 10 cents per share, effective with the November 2003 payment, and
to split its common stock two-for-one early in 2004, subject to shareholder
approval of an increase in the authorized number of common shares.

6.       FOREIGN CURRENCY TRANSLATION

      The Company accounts for foreign currency gains and losses in accordance
with SFAS No. 52 "Foreign Currency Translation." Foreign currency translation
gains and losses related to deferred taxes are recorded as a component of its
provision for income taxes, while all other foreign currency gains and losses
are reflected in Revenues and Other. For the first nine months of 2003, the
Company recorded additional deferred tax expense of $77 million as a result of
the weaker U.S. dollar. Net foreign currency gains and losses reflected in
Revenues and Other totaled $(1) million for the nine-month period.

8.   STOCK-BASED COMPENSATION

     On September 30, 2003, the Company had several stock-based employee
compensation plans. The Company accounts for those plans under the recognition
and measurement principles of Accounting Principals Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations. Under
this method, the Company records no compensation expense for stock options
granted when the exercise price of those options is equal to or greater than the
market price of the Company's common stock on the date of grant, unless the
awards are subsequently modified. The following table illustrates the effect on
income attributable to common stock and earnings per share if the Company had
applied the fair value recognition provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation," as amended, to stock-based employee compensation for
the Company's option and performance plans.

     The effects of applying SFAS No. 123, as amended, in this pro forma

timing of additional future awards cannot be predicted.

     During the second quarter of 2003, the Company issued a total of 901,105
stock appreciation rights (SARs) to non-executive employees in lieu of stock
options. The SARs will be settled in cash upon exercise. The vesting period is
over four years and the Company will record compensation expense on the vested
SARs outstanding as the price of the Company's common stock fluctuates. The
related after tax expense was $.7 million and $1.0 million for the third quarter
and year-to-date, respectively. The Company issued a 2003 award of 60,500 shares
of restricted common stock to executives in May of 2003.

10.  GEOGRAPHIC AREA INFORMATION

     Apache's exploration and production operations are a single line of
business conducted in five core geographic regions. Each of those regions
confronts the same operational concerns and has similar types of customers and
demands for our products. Where appropriate to an understanding of our business,
we will discuss the results of operations or risks and uncertainties in an
individual geographic area. Additional information regarding our geographic
locations is provided in Item 2 - Management's Discussion and Analysis of
Financial Condition and Results of Operations of this Form 10-Q, and in both
Item 7A - Quantitative and Qualitative Disclosures About Market Risk and Item 15
- Notes to the Consolidated Financial Statements of our 2002 Form 10-K.

(1)   Operating Income (Loss) consists of oil and gas production revenues less
      depreciation, depletion and amortization, asset retirement obligation
      accretion, international impairments, lease operating costs, gathering and
      transportation costs, and severance and other taxes.

11.  LITIGATION

     In June 2003, Apache and Cinergy Marketing and Trading, LLC (Cinergy)
agreed to terminate their agreement concerning marketing of Apache's U.S.
natural gas production and to dismiss the arbitration between them. The parties
reached an amicable settlement, the amounts of which were immaterial to Apache's
financial position and results of operations. Consequently, the Company began
marketing its U.S. natural gas production previously marketed by Cinergy
beginning with July 2003 production.

12.  NEW ACCOUNTING PRONOUNCEMENTS

     Effective January 1, 2003, the Company adopted SFAS No. 143, "Accounting
for Asset Retirement Obligations," which resulted in an increase to net oil and
gas properties of $410 million and additional liabilities related to asset
retirement obligations of $369 million. These entries reflect the asset
retirement obligation of Apache had the provisions of SFAS No. 143 been applied
since inception and resulted in a non-cash cumulative-


                                       12



effect increase to earnings of $27 million ($41 million pretax). Prior to
adoption of SFAS No. 143, abandonment obligations were accrued over the
productive lives of the assets through depreciation, depletion and amortization
of oil and gas properties without recording a separate liability for such
amounts.

     The following table describes all changes to the Company's asset retirement
obligation liability since adoption (in thousands):

           Asset retirement obligation at September 30, 2003....................      $       778,673
                                                                                      ===============


     Liabilities incurred during the period primarily relate to asset retirement
obligations assumed in connection with the BP Gulf of Mexico, BP North Sea and
Shell property acquisitions. Liabilities settled during the period relate to
individual properties plugged and abandoned or sold during the period. The pro
forma asset retirement obligation would have been approximately $334 million at
January 1, 2002 had the Company adopted SFAS No. 143 on January 1, 2002. For the
three and nine-month periods ended September 30, 2002, the pro forma effect on
Income Attributable to Common Stock and Net Income per Common Share would not
have been materially different than reported amounts had SFAS No. 143 been
adopted by the Company on January 1, 2002.

     In January 2003, the FASB issued Interpretation No. 46 "Consolidation of
Variable Interest Entities, an Interpretation of Accounting Research Bulletin
No. 51." Interpretation No. 46 requires a company to consolidate a variable
interest entity (VIE) if the company has a variable interest (or combination of
variable interests) that is exposed to a majority of the entity's expected
losses if they occur, receive a majority of the entity's expected residual
returns if they occur, or both. In addition, more extensive disclosure
requirements apply to the primary and other significant variable interest owners
of the VIE. This interpretation applies immediately to VIEs created after
January 31, 2003, and to VIEs in which an enterprise obtains an interest after
that date. It is also effective for the first fiscal year or interim period
beginning after December 31, 2003, to VIEs in which a company holds a variable
interest that is acquired before February 1, 2003. The guidance regarding this
interpretation is extremely complex and, although we do not believe we have an
interest in a VIE, the Company continues to assess the impact, if any, this
interpretation will have on the Company's consolidated financial statements.

     In May 2003, the FASB issued SFAS No. 150 "Accounting for Certain Financial
Instruments with Characteristics of both Liabilities and Equity." SFAS No. 150
establishes standards on how companies classify and measure certain financial
instruments with characteristics of both liabilities and equity. The statement
requires that the Company classify as liabilities the fair value of all
mandatorily redeemable financial instruments that had previously been recorded
as equity or elsewhere in the consolidated financial statements. This statement
is effective for financial instruments entered into or modified after May 31,
2003, and otherwise effective for all existing financial instruments beginning
in the third quarter of 2003. As stated in Note 4, the Company paid off the
Preferred Interests of Subsidiaries in September 2003; therefore, this statement
did not have a material impact on the Company's financial statements.

13.  SUPPLEMENTAL GUARANTOR INFORMATION

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

OVERVIEW

     Apache reported third-quarter earnings of $276 million, 90 percent above
the $145 million reported in the prior-year quarter. Third-quarter cash from
operating activities of $855 million set a new quarterly record and compared to
$385 million in the 2002 period. The quarter-over-quarter gains were primarily
fueled by:

     o   Record oil production of 228,698 Bopd, 51 percent above the prior-year
         period.

     o   Record gas production of 1.26 Bcf/d, 19 percent above the comparable
         2002 quarter.

     o   A 62 percent rise in natural gas price realizations.

     Other notable operational highlights include:

     o   Production was initiated on the Zhao Dong block in the Bohai Bay,
         offshore China in late July, further diversifying our production base.

     o   We completed the acquisition of fields in the Gulf of Mexico from Shell
         Exploration and Production Company (Shell).

     o   We announced two significant exploration successes in Egypt during the
         second quarter of 2003, the Qasr-1X well in the Khalda Concession, and
         the Alexandrite-1X well in the Matruh Concession. The Qasr-1X tested at
         a combined rate of 51.8 million cubic feet per day (MMcf/d) and 2,688
         barrels of condensate per day from two zones. The Alexandrite-1X well
         flowed at a daily rate of 20 MMcf/d and 1,683 barrels of condensate per
         day from one interval. Initial production is anticipated in the fourth
         quarter of 2003. Apache operates with a 100 percent contractor interest
         in both concessions. On November 5, 2003, we completed drilling of the
         Qasr-2X appraisal well, which confirmed the Qasr-1X discovery announced
         in July. The Qasr-2X well has a 707-foot gross hydrocarbon column and
         logs indicate net Jurassic pay at 669 feet. We expect additional
         exploratory drilling and 3-D seismic acquisition in the near future.

     o   We announced two oil discoveries in Western Australia's offshore
         Exmouth Sub-Basin, the Ravensworth-1 discovered in July, 2003 and the
         Crosby-1 discovered in early October 2003. The Crosby-1 discovery
         provides additional assurance that we have opened a new oil-play south
         of our existing Carnarvon Basin operations. Appraisal of both fields
         along with additional exploration drilling will be undertaken in early
         2004.


     For the nine-month period ending September 30, 2003, we reported record
earnings of $856 million, 135 percent above the comparable prior-year period.
Cash from operating activities, which totaled a record $2.1 billion, more than
doubled the 2002 nine-month period.

     The outlook for the fourth quarter remains strong. Current NYMEX futures
markets are showing oil and natural gas prices remaining above historical trends
through the end of the year. Coupled with our current production profile, we
expect solid results in the fourth quarter.

     On September 12, 2003, Apache's Board of Directors voted to increase the
quarterly cash dividend on our common stock 20 percent to 12 cents per share
from 10 cents. The Board also voted to split the stock two-for-one early in
2004, subject to shareholder approval of an increase in the authorized number of
common shares.

     To take advantage of historically low interest rates on commercial paper
and better position ourselves to pay down debt, if we so elect, the Company, on
September 26, 2003, repurchased and retired preferred interests issued by three
of its subsidiaries for approximately $443 million, plus an additional $1
million for accrued dividends and distributions.

CRITICAL ACCOUNTING POLICY

     In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS
No. 141, "Business Combinations," which requires the purchase method of
accounting for business combinations initiated after June 30, 2001 and
eliminates the pooling-of-interests method. In July 2001, the FASB also issued
SFAS No. 142, "Goodwill and Other Intangible Assets," which discontinues the
practice of amortizing goodwill and indefinite lived intangible assets and
initiates an annual review for impairment. Intangible assets with a determinable
useful life will continue to be amortized over that period. SFAS No. 141 and 142
clarify that more assets should be distinguished and classified between tangible
and intangible. The Company did not change or reclassify contractual mineral
rights included in oil and gas properties on the balance sheet upon adoption of
SFAS No. 141 and 142. The Company believes the treatment of such mineral rights
as property continues to be appropriate under the full cost method of accounting
for crude oil and natural gas properties. An issue has arisen regarding whether
contractual mineral rights should be classified as intangible assets rather than
properties for oil and gas companies. The amount that could be potentially
reclassified cannot be quantified until resolution regarding classification of
use rights for oil and gas companies, including full cost companies, is reached.
Our current practice, as described above, may change based upon a change in the

Natural Gas Revenues

     The Company's third-quarter 2003 natural gas production increased 203
MMcf/d, compared to the same period last year, which increased natural gas
revenues by $83 million. Production in the U.S. climbed 226 MMcf/d, concentrated
in the Gulf Coast region. Production in the Gulf Coast region includes
production from Gulf of Mexico properties acquired from Shell in July 2003, BP
p.l.c. (BP) in the first quarter of 2003, and production from the South
Louisiana properties acquired in the fourth quarter of 2002. These increases
offset natural declines in mature fields and production declines associated with
well performance, facility downtime and a hurricane. The Gulf Coast region,
which contributed 71 percent of Apache's U.S. 2003 production, is characterized
by reservoirs which demonstrate high initial rates followed by steep declines
when compared to other U.S. producing regions. A successful workover and
recompletion program, particularly offshore, helped to stem the natural declines
in the U.S. Natural decline drove down production in our U.S. Central region.
Egypt's lower production is related to scheduled facility downtime on the Khalda
Salam gas plant for maintenance and unrelated operational problems experienced
during start-up, following maintenance. The impact on production from the gas
plant events was partially offset by new wells on the Ras El Hekma and Matruh
concessions. In Australia, a gas contract expired in October 2002, reflecting
lower customer demand and resulting in 9 MMcf/d of lower sales in the third
quarter of 2003 versus the same period last year. Higher natural gas prices
contributed $167 million to third-quarter 2003 worldwide natural gas revenues.

     Apache uses a variety of strategies to manage its exposure to fluctuations
in natural gas prices, including fixed-price physical contracts and derivatives.
Approximately eight percent of our third-quarter 2003 U.S. natural gas
production was subject to long-term fixed-price physical contracts, down from 11
percent in the third quarter of 2002. We continue to amortize the unrealized
gains and losses of derivative positions closed in October and November 2001,
which were negligible in the third quarter of 2003. The following table shows
the impact on average prices of each of these items:

     Year-to-date natural gas production increased 11 percent compared to the
same period last year, increasing our natural gas revenues by $156 million.
Higher production rates in the U.S. Gulf Coast region, primarily for the reasons
discussed above, were partially offset by lower demand in Australia. Canada saw
a marginal decline in production, while Egypt's production was down four percent
year-over-year for the reasons discussed above. Natural gas prices increased 78
percent, increasing natural gas revenues by $613 million.

     Approximately nine percent of our first nine-month 2003 domestic natural
gas production was subject to long-term fixed-price physical contracts, down
from 11 percent in the 2002 period.

Crude Oil Revenues

     The Company's third-quarter 2003 oil production increased 77,555 barrels
per day (b/d), compared to the same period last year, increasing third-quarter
crude oil revenues by $195 million. Production growth occurred in all regions,
primarily concentrated in the U.S. Gulf Coast and North Sea, which benefited by
the acquisitions discussed above. Egypt's production rose 15 percent as several
new wells on the East Bahariya, South Umbarka, Umbarka and Ras El Hekma
concessions were brought online, more than offsetting lower production from the
Qarun concession related to increasing water cuts. Other contributors were
China, where production commenced in late July 2003, and Australia, where
several new wells were brought online, offsetting natural decline on other
wells. A one percent increase in oil price contributed $3 million to crude oil
revenues.

     Apache also manages its exposure to fluctuations in crude oil prices using
derivatives. We continue to amortize the unrealized gains and losses over the
original production life of derivative positions closed in October and November
2001. The following table shows the impact on prices of each of these items:

Depreciation, Depletion and Amortization

     Apache's full-cost DD&A expense is driven by many factors including certain
costs incurred in the exploration, development, and acquisition of producing
reserves, production levels, estimates of proved reserve quantities and future
development and abandonment costs. On an equivalent barrel basis, full-cost DD&A
expense increased $.39 from $6.26 per boe in the third quarter of 2002 to $6.65
per boe in 2003. The increase in the worldwide rate was driven by rate increases
in the U.S., reflecting the impact of our recent acquisitions, the addition of
the North Sea properties, first production in China and higher estimates of
future costs to extract reserves. The China and North Sea properties carry a
higher DD&A rate than our historical worldwide rate.

Lease Operating Costs

     LOE increased $78 million compared to last year's third quarter.
Seventy-three percent of the increase ($57 million) in absolute costs was
related to the acquisition of Gulf of Mexico and North Sea properties in 2003
and South Louisiana properties in the fourth quarter of 2002. Canada saw an
increase of $12 million primarily related to acquisitions completed in the
second half of 2002, higher electricity rates, and the impact of a weaker U.S.
dollar. The Company also had a higher level of workover activity compared to the
prior year.

     LOE increased 52 percent, or $175 million in the first nine months of 2003
compared to the same period in 2002. As indicated above, 69 percent of the
increase in absolute costs was related to the BP, Shell and South Louisiana
acquisitions. The remaining increase occurred in all regions, primarily in
Canada as noted above.


                                       26



Gathering and Transportation Costs

     Gathering and transportation costs include amounts paid by Apache to third
parties to transport oil and gas to a purchaser-specified delivery point. Such
costs vary based on the volume and distance shipped, and the fee charged by the
transporter, which may be price sensitive. During the third quarter of 2003, the
Company incurred $7 million more costs than in the comparable 2002 quarter, $4
million of which related to the North Sea. During the first nine months of 2003,
gathering and transportation costs were $15 million more than in the first nine
months of 2002. The higher year-over-year costs were from the North Sea ($7
million), Canada ($5 million) and the U.S. ($3 million).

Severance and Other Taxes

     Severance and other taxes, which generally are based on a percentage of oil
and gas production revenues were $25 million higher in the third quarter of 2003
compared to the same quarter last year. Severance taxes increased $4 million as
a result of increased revenues. Other taxes were $21 million higher than the
2002 quarter, $17 million of which was related to the petroleum revenue tax
(PRT) on the North Sea properties acquired from BP. The balance of the change
was primarily attributable to higher Canadian tax expense, a result of higher
prices, a weakened U.S. dollar and the fact that the 2002-period benefited from
a tax refund.

     Severance and other taxes were 103 percent higher in the first nine months
of 2003 compared to the same period in 2002. Severance taxes were $22 million
higher, a result of higher revenues, while other taxes were $28 million higher.
For the reasons above, the North Sea PRT tax and Canadian taxes were $23 million
and $7 million higher, respectively, than the prior year.

General and Administrative Expense

     Third-quarter 2003 G&A costs were $9 million higher than the year-ago
quarter. The additional $9 million is related to one-time transition costs
incurred on the Gulf of Mexico properties acquired from Shell, incremental G&A
related to North Sea operations and our new gas marketing operations. On a boe
basis, our G&A costs were $.02 per boe higher than the year-ago quarter.

     On a year-to-date basis, G&A costs were $14 million higher than the
comparable period in 2002. Forty-eight percent of the increase was associated
with G&A costs related to the acquisitions from BP and Shell discussed above.
Fifteen percent was related to the increase in the size of our gas marketing
department necessary to support the decision to market our U.S. natural gas,
which began in July 2003. The remaining 37 percent was spread among several
departments including higher insurance costs on our larger asset base,
consistent with our growth.

Financing Costs, Net

     Net financing costs for the third quarter of 2003 increased $6 million
compared to the prior-year quarter. Interest expense increased $10 million with
$5 million related to the write-off of unamortized fees triggered by the
retirement of preferred interests of subsidiaries noted below. Capitalized
interest increased $4 million driven by a higher unproved property balance. If
net financing costs included distributions from Preferred Interests of
Subsidiaries, net financing costs would have increased by approximately $4
million.

     For the first nine months of 2003, net financing costs increased $4 million
compared to the same period in 2002 driven by an $11 million increase in
interest expense for the reasons discussed above. Higher unproved property
balances increased capitalized interest by $8 million. If net financing costs
included distributions from Preferred Interests of Subsidiaries, net financing
costs would have increased by less than $1 million.

Preferred Interests of Subsidiaries

     On September 26, 2003, Apache repurchased and retired preferred interests
issued by three of its subsidiaries for approximately $443 million, plus an
additional $1 million for accrued dividends and distributions. The transactions
involved the purchase of preferred stock issued by two of the Company's
subsidiaries for approximately $82 million and the retirement of a limited
partnership interest in a partnership controlled by a subsidiary of the Company
for approximately $361 million. Apache funded the transactions with available
cash on hand and by issuing commercial paper under its existing commercial paper
facility.


                                       27



Provision for Income Taxes

     Third-quarter 2003 income tax expense was $110 million or 121 percent
higher than the comparable prior-year quarter. The higher taxes related to both
a higher net income in the 2003 quarter and $21 million of deferred tax expense
recognized on Canadian operations related to the weakening of the U.S. dollar
relative to the Canadian dollar. Our effective tax rate in the third quarter of
2003 of 41.90 percent compared to 38.09 percent in the 2002 quarter was a
consequence of the $21 million additional deferred tax expenses discussed above.
For the nine-month period of 2003, income tax expense was $410 million or 180
percent higher than the comparable 2002-period as discussed above. Similarly,
our effective tax rate of 43.31 percent for the nine-month period of 2003
compared to 37.83 percent in 2002. The additional deferred tax expense related
to changes in foreign currency exchange rates totaled $77 million for the
nine-month period of 2003.

CAPITAL RESOURCES

     Apache's primary cash needs are for exploration, development and
acquisition of oil and gas properties, operating expenses, repayment of
principal and interest on outstanding debt, and payment of dividends. The
Company funds its exploration and development activities primarily through
internally generated cash flows. Apache forecasts, for internal use by
management, an annual cash flow. The annual forecasts are revised monthly and
capital budgets are reviewed by management and adjusted as warranted by market
conditions. The Company cannot accurately predict future oil and gas prices.

Net Cash Provided by Operating Activities

     Apache's net cash provided by operating activities during the first nine
months of 2003 totaled $2.1 billion, an increase of 106 percent from $1.0
billion in the first nine months of 2002. This increase generally reflects the
impact of higher prices on oil and gas production revenues and higher production
levels relative to the prior-year period.


                                       28



Stock Transactions

     On September 12, 2003, the Company announced that its Board of Directors
voted to increase the quarterly cash dividend on its common stock to 12 cents
per share from 10 cents, effective with the November 2003 payment, and to split
its common stock two-for-one early in 2004, subject to shareholder approval of
an increase in the authorized number of common shares.

LIQUIDITY

     The Company had $43 million in cash and cash equivalents on hand at
September 30, 2003, down from $52 million at December 31, 2002. Apache's ratio
of current assets to current liabilities at September 30, 2003 was 1.05 compared
to 1.44 at December 31, 2002.

     On January 22, 2003, the Company completed a public offering of 9.9 million
shares of Apache common stock, adjusted for the five percent common stock
dividend, including underwriters' over-allotment option, for net proceeds of
approximately $554 million. The proceeds were used toward Apache's acquisition
from BP of producing properties in the North Sea and the Gulf of Mexico.

     Apache believes that cash on hand, net cash generated from operations,
short-term investments, and unused committed borrowing capacity under its $1.5
billion global credit facility will be adequate to satisfy future financial
obligations and liquidity needs. The $750 million 364-day U.S. credit facility,
which was scheduled to mature on June 1, 2003, was extended on the same terms
for an additional one-year period and is currently scheduled to mature on May
28, 2004. As of September 30, 2003, Apache's available borrowing capacity under
its global credit facility was $1.2 billion.

     Occasionally, the Company accesses capital markets to fund acquisitions,
repay debt, and enhance liquidity. On May 15, 2003, Apache Finance Canada
Corporation (Apache Finance Canada) issued $350 million of 4.375 percent,
12-year, senior unsecured notes in a private placement. The notes are
irrevocably and unconditionally guaranteed by Apache. Interest is payable
semi-annually on May 15 and November 15 of each year commencing on November 15,
2003. The notes were sold pursuant to Rule 144A and Regulation S, and may not be
offered or sold in the United States absent registration or an applicable
exemption from the registration requirements of the Securities Act of 1933, as
amended. If changes in relevant tax laws occur that would require Apache Finance
Canada to pay additional amounts under the terms of the indenture, Apache
Finance Canada has the right to redeem the notes prior to maturity. In addition,
the notes are redeemable, as a whole or in part, at Apache Finance Canada's
option, subject to a make-whole premium. The proceeds were used to reduce bank
debt and outstanding commercial paper and for general corporate purposes.

FUTURE TRENDS

     Our objective is to build a company of lasting value by pursuing profitable
growth through a combination of drilling and acquisitions. Our investment
decisions are subjected to strict rate of return criteria and generally fall in
the categories identified below, depending on which phase of the price and cost
cycle we may be in. Those categories include:

         -    exploiting our existing property base;
         -    acquiring properties to which we can add value; and
         -    drilling high-potential exploration prospects.

Exploiting Existing Asset Base

     We seek to maximize the value of our existing asset base by increasing
production and reserves while reducing operating costs per unit. In order to
achieve these objectives, we actively pursue production enhancement
opportunities such as workovers, recompletions and moderate risk drilling, while
divesting marginal and non-strategic properties and identifying other activities
to reduce costs. Given the significant acquisitions and discoveries over the
last few years, including the properties recently acquired from BP and Shell, we
have increased our inventory of exploitation opportunities.


                                       29



Acquiring Properties to Which We Can Add Value

     We seek to purchase reserves at appropriate prices by generally avoiding
auction processes, where we are competing against other buyers. Our aim is to
follow each acquisition with a cycle of reserve enhancement, property
consolidation and cash flow acceleration, facilitating asset growth and debt
reduction.

Investing in High-Potential Exploration Prospects

     We seek to concentrate our exploratory investments in a select number of
international areas and to become one of the dominant operators in those
regions. We believe that these investments, although higher-risk, offer
potential for attractive investment returns and significant reserve additions.
Our international investments and exploration activities are a significant
component of our long-term growth strategy. They complement our domestic
operations, which are more development oriented.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Major market risk exposure continues to be the pricing applicable to our
oil and gas production. Realized pricing is primarily driven by the prevailing
worldwide price for crude oil and spot prices applicable to our United States
and Canadian natural gas production. Historically, prices received for oil and
gas production have been volatile and unpredictable.

     Apache sells all of its Egyptian crude oil and natural gas production to
the Egyptian General Petroleum Corporation (EGPC) for U.S. dollars. Weak
economic conditions in Egypt continue to impact the timeliness of receipts from
EGPC; however, the situation has not deteriorated since year-end and Apache
continues to receive payments.

     U.S. and Canadian energy markets continue to evolve into a single energy
market. In light of this ongoing transformation, we adopted the U.S. dollar as
our functional currency in Canada, effective October 1, 2002. The U.S. dollar is
now the functional currency for all of our foreign operations.

     The information set forth under "Commodity Risk," "Interest Rate Risk" and
"Foreign Currency Risk" in Item 7A of our annual report on Form 10-K for the
year ended December 31, 2002, is incorporated herein by reference. Information
about market risks for the quarter ended September 30, 2003 does not differ
materially from the disclosure in our 2002 Form 10-K, except as noted below.

     The Company considers its interest rate risk exposure to be minimal as a
result of fixing interest rates on approximately 87 percent of the Company's
debt. At September 30, 2003, total debt included $323 million of floating-rate
debt. As a result, Apache's annual interest costs in 2003 will fluctuate based
on short-term interest rates on approximately 13 percent of its total debt
outstanding at September 30, 2003. The impact on cash flow of a 10 percent
change in the floating interest rate would be approximately $100,000 per
quarter.

     On September 30, 2003, the Company had open natural gas derivative
positions with a fair value of $(22) million. A 10 percent change in natural gas
prices would change the fair value by plus or minus $38 million. The Company
also had open oil price swap positions with a fair value of $(12) million. A 10
percent change in oil prices would change the fair value by plus or minus $17
million. Notional volumes associated with the Company's derivative contracts are
shown in Note 2 to the Company's consolidated financial statements.


ITEM 4 - CONTROLS AND PROCEDURES

     G. Steven Farris, the Company's President, Chief Executive Officer and
Chief Operating Officer, and Roger B. Plank, the Company's Executive Vice
President and Chief Financial Officer, evaluated the effectiveness of our
disclosure controls and procedures within the last 90 days preceding the date of
this report. Based on that review and as of the date of that evaluation, the
Company's disclosure controls were found to be adequate, providing effective
means to insure that we timely and accurately disclose the information we are
required to disclose under applicable laws and regulations. Also, we made no
significant changes in internal controls or any other factors that could affect
our internal controls since our most recent internal controls evaluation.


                                       30



FORWARD-LOOKING STATEMENTS AND RISK

     Certain statements in this report, including statements of the future
plans, objectives, and expected performance of the Company, are forward-looking
statements that are dependent upon certain events, risks and uncertainties that
may be outside the Company's control, and which could cause actual results to
differ materially from those anticipated. Some of these include, but are not
limited to, the market prices of oil and gas, economic and competitive
conditions, inflation rates, legislative and regulatory changes, financial
market conditions, political and economic uncertainties of foreign governments,
future business decisions, and other uncertainties, all of which are difficult
to predict.

     There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves and in projecting future rates of production and the
timing of development expenditures. The total amount or timing of actual future
production may vary significantly from reserves and production estimates. The
drilling of exploratory wells can involve significant risks, including those
related to timing, success rates and cost overruns. Lease and rig availability,
complex geology and other factors can affect these risks. Although Apache may
make use of futures contracts, swaps, options and fixed-price physical contracts
to mitigate risk, fluctuations in oil and gas prices, or a prolonged
continuation of low prices, may adversely affect the Company's financial
position, results of operations and cash flows.
