                                 PROXY STATEMENT

GENERAL

The board of directors is soliciting proxies to be used at a special meeting of
stockholders of Apache Corporation to be held on [December 18,] 2003. In this
proxy statement "Apache," "the Company" and "we" refer to Apache Corporation.
This proxy statement and the enclosed proxy card will be mailed on or about
[November ___,] 2003.

PURPOSE OF THE SPECIAL MEETING

At the special meeting, stockholders will vote on whether to amend the Company's
Restated Certificate of Incorporation to authorize additional shares of the
Company's common stock, as outlined in the accompanying notice of meeting, and
on any other business that properly comes before the meeting, including matters
incident to the conduct of the meeting such as any motion for adjournment or
postponement. As of the date of this proxy statement, the Company is not aware
of any business to come before the meeting other than the approval of the
proposed amendment to the Restated Certificate of Amendment. There are no rights
of appraisal or similar rights of dissenters arising from matters to be acted on
at the meeting.

WHO CAN VOTE

Only stockholders of record holding shares of Apache common stock at the close
of business on the record date, [October 29,] 2003, are entitled to receive
notice of the special meeting and to vote the shares of Apache common stock they
held on that date. As of [October 29,] 2003, there were __________ shares of
Apache common stock issued and outstanding. Holders of Apache common stock are
entitled to one vote per share. The enclosed proxy card shows the number of
shares that you are entitled to vote.

Apache currently has outstanding one series of preferred stock - the 5.68%
Cumulative Preferred Stock, Series B (the "Series B Preferred Stock"). The
holders of the depositary shares, each representing 1/10th of a share of Series
B Preferred Stock, are not entitled to any voting rights, except under certain
circumstances relating to non-payment of dividends on the Series B Preferred
Stock. As of the date of this proxy statement, all dividend payments on the
Series B Preferred Stock were current.

HOW TO VOTE

If your shares of Apache common stock are held by a broker, bank or other
nominee (in "street name"), you will receive instructions from them on how to
vote your shares.

If you hold shares of Apache common stock in your own name (as a "stockholder of
record"), you may give instructions on how your shares are to be voted by:

   -  marking, signing, dating and returning the enclosed proxy card in the
      postage-paid envelope provided.

                                       1

   -  using the toll-free telephone number or Internet voting site listed on the
      enclosed proxy card. Specific directions for using the telephone and
      Internet voting systems are shown on the proxy card.

When using telephone or Internet voting, the systems verify that you are a
stockholder through the use of a company number for Apache and a unique control
number for you. IF YOU VOTE BY TELEPHONE OR INTERNET, PLEASE DO NOT MAIL THE
ENCLOSED PROXY CARD.

Whichever of these methods you use to transmit your instructions, your shares of
Apache common stock will be voted as you direct. If you sign and return the
enclosed proxy card or otherwise designate the proxies named on the proxy card
to vote on your behalf, but do not specify how to vote, your shares will be
voted FOR the proposed amendment. If other matters of business not presently
known are properly raised at the meeting, the proxies will vote on the matters
in accordance with their best judgment.

VOTING 401(k) PLAN SHARES

If you are an employee or former employee participating in the Apache 401(k)
Savings Plan and have shares of Apache common stock credited to your plan
account as of the record date, such shares are shown on the enclosed proxy card
and you have the right to direct the plan trustee regarding how to vote those
shares. The trustee for the 401(k) plan is Fidelity Management Trust Company.

The trustee will vote the shares in your plan account in accordance with your
instructions. If you do not send instructions (by voting your shares as provided
above under "How to Vote") or if your proxy card is not received by [December
15,] 2003, the shares credited to your account will be voted by the trustee in
the same proportion as it votes shares for which it did receive timely
instructions.

REVOKING A PROXY

You may revoke a proxy before it is voted by submitting a new proxy with a later
date (by mail, telephone or Internet), by voting at the meeting, or by filing a
written revocation with Apache's corporate secretary. Your attendance at the
special meeting will not automatically revoke your proxy.

QUORUM AND VOTES NEEDED

The presence at the special meeting, in person or by proxy, of the holders of a
majority of the shares of Apache common stock outstanding on the record date
will constitute a quorum, permitting the business of the meeting to be
conducted. The affirmative vote of a plurality of the votes cast at the special
meeting is required for the approval of the proposed amendment.

HOW THE VOTES ARE COUNTED

Representatives of Wells Fargo Bank Minnesota, N.A. will tabulate the votes and
act as inspectors of election. A properly signed proxy marked to "withhold"
authority for the approval of the proposed amendment will be counted for quorum
purposes but not for voting purposes. If you are present or represented by proxy
at the special meeting and you abstain, your abstention, as well as broker
non-votes, are not counted as votes cast on any matter to which they relate.

                                       2

         APPROVAL OF AMENDMENT TO RESTATED CERTIFICATE OF INCORPORATION
                      TO AUTHORIZE ADDITIONAL COMMON STOCK
                         (PROPOSAL NO. 1 ON PROXY CARD)

TERMS AND REASON FOR AMENDMENT

The authorized capital stock of the Company presently consists of 220,000,000
shares which are divided into 215,000,000 shares of common stock, par value of
$1.25 per share, and 5,000,000 shares of no par value preferred stock. On
September 11, 2003, the board of directors conditionally approved a two-for-one
stock split to be effected in the form of a stock dividend of one share of
common stock for each currently issued share of common stock, payable on
[January 14, 2004,] to stockholders of record of the Company on [December 31,
2003.] The Company does not currently have a sufficient number of authorized but
unissued shares of common stock available to effectuate the stock split, so it
is conditioned upon, and shall be due and payable only upon, approval by the
stockholders of the proposed amendment, the filing of the necessary documents
with the Delaware Secretary of State to amend the Restated Certificate of
Incorporation, and compliance with all applicable laws, regulations, and rules
of the New York and Chicago Stock Exchanges.

The board of directors has unanimously adopted a resolution setting forth a
proposed amendment to Article Fourth of the Company's Restated Certificate of
Incorporation that would double the number of authorized shares of common, with
the authorized shares of common stock increased from 215,000,000 shares with a
par value of $1.25 per share to 430,000,000 shares with a par value of $0.625
per share. The resolution adopted by the board of directors, which is being
presented for approval by the stockholders at the special meeting, recommended
that the Company's Restated Certificate of Incorporation be amended to replace
the current first paragraph of Article Fourth with a new first paragraph of
Article Fourth reading in its entirety as follows:

      "FOURTH. The total number of shares of all classes of stock which this
      Company shall have authority to issue is 435,000,000 which shall be
      divided into (a) 430,000,000 shares of common stock having a par value of
      $0.625 per share and (b) 5,000,000 shares of no par value preferred
      stock."

BOARD RECOMMENDATION

The board of directors believes that the proposed amendment to increase the
number of authorized shares of common stock is in the best interests of the
Company and stockholders and recommends that stockholders vote FOR the proposed
amendment.

INFORMATION ON FUTURE ISSUANCE OF SHARES

Although shares authorized over and above the number required to fund the stock
split described above would be available for issuance for other corporate
purposes without further action by the stockholders, unless required by the
Company's Restated Certificate of Incorporation or Bylaws, by the rules of any
stock exchange on which the common stock may be listed, or by applicable law,
the board of directors has no present plans to issue any additional shares of
common stock, except for the funding of the stock split described above and
routine issuances of reserved shares to employees and directors in connection
with the exercise of stock options, the vesting of restricted stock, and the
Company's deferred compensation plans.

                                       3

In the event additional shares of common stock are issued by the Company,
existing holders of shares of common stock would have no preemptive rights under
the Company's Restated Certificate of Incorporation or otherwise to purchase any
of such shares. It is possible that shares of common stock may be issued at a
time and under circumstances that may dilute the voting power of existing
stockholders, decrease earnings per share and decrease the book value per share
of shares presently held.

                  SECURITIES OWNERSHIP AND PRINCIPAL HOLDERS

The following tables set forth, as of [August 31,] 2003, the beneficial
ownership of each director or nominee for director of the Company, the chief
executive officer, the four other most highly compensated executive officers,
and all directors and executive officers of the Company as a group. All
ownership information is based upon filings made by those persons with the SEC
and upon information provided to the Company. (All share numbers in the table
