This registration statement on Form S-8 is being filed by the registrant, Apache Corporation (“Apache” or the “Registrant”), for the purpose of registering 15,000,000 shares of common stock, par value $0.625 per share (“Apache Common Stock”), for issuance under the terms of the Apache Corporation 2007 Omnibus Equity Compensation Plan. Such 15,000,000 shares of Apache Common Stock have been reserved and authorized for issuance from Apache’s authorized and unissued capital stock.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

The following documents filed by Apache with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), Commission File No. 001-04300, are incorporated by reference into this Registration Statement:

(1)	Annual Report on Form 10-K for the year ended December 31, 2006, filed with the Commission on March 1, 2007.
(2)	Quarterly Report on Form 10-Q for the quarter ended March 31, 2007, filed with the Commission on May 10, 2007.
(3)	Current Reports on Form 8-K, filed with the Commission on January 18, 2007, January 26, 2007, March 21, 2007, March 30, 2007, April 12, 2007, April 16, 2007, and April 18, 2007.
(4)	All documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective amendment which indicates that all securities offered have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents.

The descriptions set forth below of the common stock of Apache, par value $0.625 per share (“Apache Common Stock”), the preferred stock and the Rights (as defined below) constitute brief summaries of certain provisions of Apache’s Restated Certificate of Incorporation, Apache’s Bylaws and the Rights Agreement between Apache and Wells Fargo Bank, N.A. (“Wells Fargo”), formerly Norwest Bank Minnesota, N.A., and are qualified in their entirety by reference to the relevant provisions of such documents, all of which are listed under Item 8 as exhibits to this Registration Statement and are incorporated herein by reference.

Apache Common Stock

All outstanding shares of Apache Common Stock are fully paid and nonassessable, and all holders of Apache Common Stock have full voting rights and are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. The Board of Directors of Apache is classified into three groups of approximately equal size, one-third elected each year. Stockholders do not have the right to cumulate votes in the election of directors and have no preemptive or subscription rights. Apache Common Stock is neither redeemable nor convertible, and there are no sinking fund provisions relating to such stock.

Subject to preferences that may be applicable to any shares of preferred stock outstanding at the time, holders of Apache Common Stock are entitled to dividends when and as declared by the Board of Directors from funds legally available therefor and are entitled, in the event of liquidation, to share ratably in all assets remaining after payment of liabilities.

Apache’s current policy is to reserve one ten-thousandth (1/10,000) of a share of Series A Preferred Stock (as defined below) for each share of Apache Common Stock issued in order to provide for possible exercises of Rights (as defined below) under Apache’s existing Rights Agreement.

II-1

The currently outstanding Apache Common Stock and the Rights (as defined below) under Apache’s existing Rights Agreement are listed on the New York Stock Exchange and the Chicago Stock Exchange and quoted on the NASDAQ National Market. Wells Fargo is the transfer agent and registrar for Apache Common Stock.

Apache typically mails its annual report to stockholders within 120 days after the end of its fiscal year. Notices of stockholder meetings are mailed to record holders of Apache Common Stock at their addresses shown on the books of the transfer agent and registrar.

Preferred Stock

Apache has five million shares of no par preferred stock authorized, of which (i) 100,000 shares have been designated Series A Junior Participating Preferred Stock (“Series A Preferred Stock”) and authorized for issuance pursuant to the Rights (as defined below) that trade with Apache Common Stock, and (ii) 100,000 shares have been designated 5.68% Cumulative Preferred Stock, Series B (“Series B Preferred Stock”). A total of 100,000 shares of Series B Preferred Stock are currently outstanding, and shares of Series A Preferred Stock have been reserved for issuance in accordance with the Rights Agreement relating to the Rights. Additional shares of preferred stock may be authorized for issuance and issued by the Board of Directors with such voting powers and in such classes and series, and with such designations, preferences, and relative, participating, optional or other special rights, qualifications, limitations or restrictions thereof (including conversion into or exchange for Apache Common Stock or other securities of Apache or its subsidiaries), as may be stated and expressed in the resolution or resolutions providing for the issuance of such preferred stock adopted by the Board of Directors providing for the issuance of such preferred stock.

Rights

In December 1995, Apache declared a dividend of one right (a “Right”) for each 2.31 shares (adjusted for subsequent stock dividends and a two-for-one stock split) of Apache Common Stock outstanding on January 31, 1996. Each full Right entitles the registered holder to purchase from Apache one ten-thousandth (1/10,000) of a share of Series A Preferred Stock at a price of $100 per one ten-thousandth of a share, subject to adjustment. The Rights are exercisable ten calendar days following a public announcement that certain persons or groups have acquired 20 percent or more of the outstanding shares of Apache Common Stock or ten business days following commencement of an offer for 30 percent or more of the outstanding shares of Apache Common Stock. Unless and until the Rights become exercisable, they will be transferred with and only with the shares of Apache Common Stock.

In addition, if a person or group becomes the beneficial owner of 20 percent or more of the outstanding shares of Apache Common Stock (a “flip in event”), each Right will become exercisable for shares of Apache Common Stock at 50 percent of the then market price of Apache Common Stock. If a 20-percent stockholder of Apache acquires Apache, by merger or otherwise, in a transaction where Apache does not survive or in which Apache Common Stock is changed or exchanged (a “flip over event”), the Rights become exercisable for shares of the common stock of the company acquiring Apache at 50 percent of the then market price of Apache Common Stock. Any Rights that are or were beneficially owned by a person who has acquired 20 percent or more of the outstanding shares of Apache Common Stock, and who engages in certain transactions or realizes the benefits of certain transactions with Apache, will become void. If an offer to acquire all of the outstanding shares of Apache Common Stock is determined to be fair by Apache’s board of directors, the transaction will not trigger a flip in event or a flip over event. Apache may also redeem the Rights at $.01 per Right at any time until ten business days after public announcement of a flip in event. These rights were originally scheduled to expire on January 31, 2006. Effective as of that date, the rights were reset to one right per share of common stock and the expiration was extended to January 31, 2016. Unless the Rights have been previously redeemed, all shares of Apache Common Stock issued by Apache after January 31, 1996, will include Rights, including the Apache Common Stock issuable under the terms of the Apache Corporation 2007 Omnibus Equity Compensation Plan.

Item 4. Description of Securities

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Section 145 of the Delaware General Corporation Law (“DGCL”), inter alia, authorizes a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of the corporation) because the person is or was a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the suit or proceeding if the person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reason to believe his conduct was unlawful. Similar indemnity is authorized against expenses (including attorneys’ fees) actually and reasonably incurred in defense or settlement of any pending, completed or threatened action or suit if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and provided further that (unless a court of competent jurisdiction otherwise provides) the person shall not have been adjudged liable to the corporation. The indemnification may be made only as authorized in each specific case upon a determination by the stockholders or disinterested directors that indemnification is proper because the indemnitee has met the applicable standard of conduct.

Section 145 of the DGCL further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against him and incurred by him in any capacity, or arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him. Apache maintains policies insuring the officers and directors of Apache and its subsidiaries against certain liabilities for actions taken in their capacities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”).

Article VII of Apache’s Bylaws provides, in substance, that directors, officers, employees and agents of Apache shall be indemnified to the extent permitted by Section 145 of the DGCL. Additionally, the Seventeenth Article of Apache’s Restated Certificate of Incorporation eliminates in certain circumstances the monetary liability of directors of Apache for a breach of their fiduciary duty as directors. These provisions do not eliminate the liability of a director (i) for a breach of a director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions by a director not in good faith; (iii) for acts or omissions by a director involving intentional misconduct or a knowing violation of the law; (iv) under Section 174 of the DGCL (relating to the declaration of dividends and purchase or redemption of shares in violation of the DGCL); and (v) for transactions from which the director derived an improper personal benefit.

Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

     (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

     (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement relating to the securities offered herein shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

     (5) That, for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

     (6) That, for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-5

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

II-6

Ladies and Gentlemen:

     We are rendering this opinion in our capacity as special counsel for Apache Corporation, a Delaware corporation (“Apache” or the “Company”), in connection with the Registration Statement on Form S-8 (the “Registration Statement”) filed on or about this date by Apache under the Securities Act of 1933, as amended, and relating to 15,000,000 shares of Apache’s common stock, par value $0.625 per share (“Apache Common Stock”), issued under the agreement described in the Registration Statement (the “Plan”).

     In connection therewith, we have examined originals or copies of (i) the Registration Statement, (ii) the Plan, (iii) the Certificate of Incorporation of the Company, as amended, (iv) the Bylaws of the Company, as amended, (v) certain resolutions of the Board of Directors of the Company certified to us to be true and correct by the Company’s Secretary, and (vi) such other documents and records as we have deemed necessary and relevant for the purposes hereof.

     We have relied upon certificates of public officials and certificates and statements of officers of Apache as to certain matters of fact relating to this opinion and have made such investigations of law as we have deemed necessary and relevant as a basis hereof. We have not independently verified any factual matter relating to this opinion.

     We have assumed and have not verified (i) the genuineness of all signatures on all documents that we have examined, (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to us as originals, and (iv) the conformity to the authentic originals of all documents supplied to us as certified or photostatic or faxed copies.

     On the basis of our foregoing, subject to the limitations and assumptions set forth herein, and having due regard for such legal considerations that we have deemed relevant, it is our opinion that the 15,000,000 shares of Apache Common Stock to be registered have been duly authorized by Apache, and when issued in accordance with the terms and conditions of the Plan, will be validly issued, fully paid and non-assessable.
