               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INCORPORATION OF DOCUMENTS BY REFERENCE.

The following documents filed by Apache Corporation (the "Registrant" or
"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. 1-4300, are incorporated by reference into this
Registration Statement:

     (1) Annual Report on Form 10-K for the fiscal year ended December 31,
         1996.

     (2) 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 $1.25
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 Norwest Bank Minnesota, N. A. ("Norwest"), 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.

     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.  Norwest is the transfer agent
and registrar for Apache Common Stock.


                                     II - 1

<PAGE>   4


         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 25,000 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.
No preferred stock is currently outstanding; however, shares of Series A
Preferred Stock have been reserved for issuance in accordance with the Rights
Agreement relating to the Rights.  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 outstanding share of Apache Common Stock effective January 31, 1996. 
Each 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.  If Apache engages in certain business
combinations or a 20-percent stockholder engages in certain transactions with
Apache, the Rights become exercisable for Apache Common Stock or the common
stock of the corporation acquiring Apache (as the case may be) at 50 percent of
the then-market price.  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.  Apache may redeem the
Rights at $.01 per Right at any time until ten business days after public
announcement that a person has acquired 20 percent or more of the outstanding
shares of Apache Common Stock.  Unless the Rights have been previously redeemed,
all shares of Apache Common Stock will include Rights, including the Apache
Common Stock issuable under the terms of the Apache Corporation 1996 Performance
Stock Option Plan.

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 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 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.


                                     II - 5

<PAGE>   8


     (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.

(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 of Article 15, 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.

the acquiring or successor corporation and for the protection of any
outstanding Conditional Grants by the substitution on an equitable basis of
appropriate stock of the Company or of the merged, consolidated or otherwise
reorganized corporation which will be issuable with respect to the Stock,
provided that no additional benefits shall be conferred upon the Consultant

equal to the Fair Market Value of the Stock to which Consultant has a
conditional entitlement under such Conditional Grants at the date of the
cancellation of the Conditional Grants; and (iii) make any other adjustments or
amendments to the outstanding Conditional Grants as the Board deems

                              TERMS AND CONDITIONS

     1. Grant of Option.  Subject to the terms and conditions of this
Agreement, the Company hereby grants to Patrick an option (the "Option") to
purchase 20,000 shares Stock at a price per share of $*  (the "Option Price").
The Option is not intended to qualify as an incentive stock option under
Section 422 or any successor section(s) of the Internal Revenue Code.
Notwithstanding anything to the contrary set forth in this Agreement, the grant
of the foregoing Option shall become unconditional, subject to the vesting,
termination and forfeiture provisions set forth herein.

     2. Vesting.  The Option shall become exercisable in increments after each
of the first three years of continuous service pursuant to the Consulting
Agreement after the date of this Agreement (defined as the "Vesting Schedule"),
as follows:


<TABLE>
<CAPTION>
        Required Number of Years           Cumulative Proportion of Shares of
  of Continuous Consulting Service after            Stock Exercisable
          the Date of this                          after Such Period
               Agreement                    of Continuous Consulting Service
- -----------------------------------------  -------------------------------------
<S>                                        <C>
                    1                                   33 percent
                    2                                   67 percent
                    3                                   100 percent
</TABLE>

Except as set forth in Sections 5 or 6 hereof, the Option shall not be
exercisable as to any shares of Stock as to which the continuous consulting
service requirement shall not be satisfied, regardless of the circumstances
which under Patrick's service for the Company shall be terminated.  The number
of shares of Stock as to which the Option may be exercised shall be cumulative,
as indicated above, so that once the Option shall become exercisable as to any
shares of Stock it shall continue to be exercisable as to such shares of Stock
until expiration or termination of the Option as provided in Section 7 hereof.

     3. Method for Exercising the Option.  The Option may be exercised only by
delivery in person or through certified or registered mail, to the Company at
its principal office in Houston, Texas (Attention:  Office of the Secretary) of
written notice specifying the Option that is being exercised and the number of
shares of Stock with respect to which the Option is being exercised.  The
notice must be accompanied by payment of the total Option Price.  At the
request of the Company, such notice shall contain Patrick's representation that
he is purchasing such Stock for investment purposes only and his agreement not
to sell or distribute any

  Inc. Composite Transactions Reporting System on the date of grant.

Stock purchased pursuant to the Option in any manner
or to take any other action with respect to any Stock purchased  pursuant to
the Option that is in violation of the Securities Act of 1933, as
amended, or any applicable state law.  Patrick acknowledges that all
certificates representing shares of Stock acquired pursuant to the Option may
have affixed thereto a restrictive legend to evidence the requirement for
compliance with the Securities Act of 1933, as amended, and any applicable
state securities laws.  If the shares of Stock acquired pursuant to this Option
are not issued in a registered transaction, the following legend shall be
printed on all certificates representing such shares of Stock:

     The shares represented by this Certificate are "restricted
     securities" as defined in Rule 144 under the Securities Act of
     1933, as amended, and may not be sold or transferred except in
     transactions which comply with Rule 144 or, in the opinion of
     counsel acceptable to the issuer, are exempt therefrom.

     The purchase of such Stock shall take place at the principal offices of
the Company upon delivery of the notice of exercise, at which time the total
Option Price for the Stock  shall be paid in full by any of the following
methods or any combination of the following methods:

     (a) In cash or by personal, certified or cashier's check payable to the
order of Apache Corporation;

     (b) The delivery to the Company of certificates representing a number of
shares of Stock  then owned by Patrick, the Fair Market Value of which equals
the Option Price of the Stock purchased pursuant to the Option, properly
endorsed for transfer to the Company; provided, however, that no Option may be
exercised by delivery to the Company of certificates representing Stock, unless
such Stock has been held by Patrick for more than six months; for purposes of
this Agreement, the Fair Market Value of any shares of Stock delivered in
payment of the Option Price upon exercise of the Option shall be the Fair
Market Value as of the Exercise Date; or

     (c) By delivery to the Company of a properly executed notice of exercise
together with irrevocable instructions to a broker to deliver to the Company
promptly the amount of the proceeds of the sale of all or a portion of the
Stock or of a loan from the broker to Patrick necessary to pay the Option
Price, in each case in a form satisfactory to the Office of the Secretary.

     Upon such notice to the Office of the Secretary and payment of the total
Option Price, the exercise of the Option shall be deemed to be effective, and a
properly executed certificate or certificates representing the Stock so
purchased shall be issued by the Company and delivered to Patrick.  If
certificates representing Stock are used to pay all or part of the Option
Price, separate certificates for the same number of shares of Stock shall be
issued and delivered to Patrick representing each certificate used to pay the
Option Price, and an additional certificate shall be issued and delivered to
Patrick representing the additional shares of Stock, in excess of the Option
Price, to which Patrick is entitled as a result of the exercise of the Option.

     4. Adjustment of the Option.

        (a) Adjustment by Stock Split, Stock Dividend, Etc.  If at any time the
Company increases or decreases the number of its outstanding shares of Stock,
or changes in any way the rights and privileges of such shares of Stock, by
means of the payment of a Stock dividend or the making of any other
distribution on such shares payable in Stock, or though a stock split or
subdivision of shares of Stock, or a consolidation or combination of shares of
Stock, or through a reclassification or recapitalization involving the Stock,
the numbers, rights and privileges of the shares of Stock included in the
Option shall be increased, decreased or changed in like manner as if such
shares of Stock had been issued and outstanding, fully paid and non-assessable
at the time of such occurrence.

        (b) Dividends Payable in Stock of Another Corporation, Etc.  If at any
time the Company pays or makes any dividend or other distribution upon the
Stock payable in securities or other property (except money or Stock), a
proportionate part of such securities or other property shall be set aside and
delivered to Patrick upon issuance of Stock purchased at the time of the
exercise of the Option.  The securities and other property delivered to Patrick
upon exercise of the Option shall be in the same ratio to the total securities
and property set aside for Patrick as the number of shares of Stock with
respect to which the Option is then exercised is to the total shares of Stock
subject to the Option.  Prior to the time that any such securities or other
property are delivered to Patrick in accordance with the foregoing, the Company
shall be the owner of such securities or other property and shall have the
right to vote the securities, receive any dividends payable on such securities,
and in all other respects shall be treated as the owner.  If securities or
other property which have been set aside by the Company in accordance with this
Section 4 are not delivered to Patrick because the Option is not exercised,
then such securities or other property shall remain the property of the Company
and shall be dealt with by the Company as it shall determine in its sole
discretion.

        (c) Other Changes in Stock.  In the event there shall be any change,
other than as specified in Subsections 4 (a) and (b) hereof, in the number or
kind of outstanding shares of Stock or of any stock or other securities into
which the Stock shall be changed or for which it shall have been exchanged,
then and if the Company shall in its discretion determine that such change
equitably requires an adjustment in the number or kind of shares subject to the
Option, such adjustments shall be made by the Company and shall be effective
for all purposes of this Agreement.

        (d) Apportionment of Option Price.  Upon any occurrence described in
Subsections 4 (a), (b) and (c) hereof, the aggregate Option Price for the
shares of Stock then subject to the Option shall remain unchanged and shall be
apportioned ratably over the increased or decreased number or changed kinds of
securities or other properties subject to the Option.


                                      -4-
<PAGE>   5

        (e) Rights to Subscribe.  If at any time the Company grants, to the
holders of its Stock, rights to subscribe pro rata for additional shares of
Stock or for any other securities of the Company or of any other corporation,
there shall then be reserved with respect to the number of shares subject to
the Option, the Stock or other securities for which Patrick would have been
entitled to subscribe if immediately prior to such grant Patrick had exercised
his entire Option.  If, upon exercise of the Option, Patrick subscribes for the
additional Stock or other securities, the Option Price shall be increased by
the amount of the price that would have been payable by Patrick for such
additional Stock or other securities.

     5. Reorganization.  If the provisions of Section 6 hereof do not apply and
if the Company is merged or consolidated with another corporation and the
Company is not the surviving corporation, or if all or substantially all of the
assets or more than 20 percent of the outstanding voting stock of the Company
is acquired by any other corporation, entity or person, or in case of a
reorganization (other than a reorganization under the United States Bankruptcy
Code) or upon the liquidation of the Company, the Company or the board of
directors of any corporation assuming the obligations of the Company, shall, as
to the unexercised portion of the Option, either (a) make appropriate provision
for the protection of the Option, by the substitution on an equitable basis of
appropriate stock of the Company or of the merged, consolidated or otherwise
reorganized corporation which will be issuable with respect to the Stock,
provided that no additional benefits shall be conferred upon Patrick as a
result of such substitution, and the excess of the aggregate Fair Market Value
of the shares subject to the Option immediately after such substitution over
the Option Price thereof is not more than the excess of the aggregate Fair
Market Value of the shares of Stock subject to the Option immediately before
such substitution over the Option Price thereof, or (b) upon written notice to
Patrick, provide that the unexercised portion of the Option shall be exercised
within a specified number of days of the date of such notice or the Option will
be terminated.  In the latter event, the Company shall accelerate the exercise
dates of the Option so that the Option becomes fully exercisable prior to any
such event.

     6. Change in Control.

        (a) Effect of Change in Control on Option.  Notwithstanding any other
provision of this Agreement to the contrary, in the event of a change in        
control of the Company as defined in Subsection 6(c) hereof, the Company may,
in its sole discretion, without obtaining stockholder approval, take any or all
the following actions:  (i) accelerate the exercise dates of the Option or make
the Option fully vested and exercisable; (ii) grant a cash bonus award to
Patrick equal to the amount necessary to pay the Option Price for all or any
portion of the Option; (iii) pay cash to Patrick in exchange for the
cancellation of the Option in an amount equal to the difference between the
Option Price and the greater of the tender offer price for underlying Stock or
the Fair Market Value of the Stock on the date of the cancellation of the
Option; and (iv) make any other adjustment or amendment to the Option, subject
to the provisions of Subsection 10(b) hereof.


                                      -5-
<PAGE>   6
        (b) Limitation on Payments.  If the provisions of this Section 6 would
result in the receipt by Patrick of a payment within the meaning of Section
280G or any successor section(s) of the Internal Revenue Code and the
regulations promulgated thereunder and if the receipt of such payment by
Patrick would, in the opinion of independent tax counsel of recognized standing
selected by the Company, result in the payment by Patrick of any excise tax
provided for in Sections 280G and 4999 or any successor section(s) of the
Internal Revenue Code, then the amount of such payment shall be reduced to the
extent required, in the opinion of such independent tax counsel, to prevent the
imposition of such excise tax; provided, however, that the Company, in its sole
discretion, may authorize the payment of all or any portion of the amount of
such reduction to Patrick.

        (c) Definitions.  For purposes of this Agreement, a "change in control"
shall mean any of the events specified in the Apache Corporation Income
Continuance Plan or any successor plan(s) which constitute a change in control
within the meaning of such plan.

     7. Expiration and Termination of the Option.  The Option shall expire five
years from the date of this Agreement (the period from the date of this
Agreement to the expiration date is defined as the "Option Period") or prior to
such time as follows:

        (a) If the Consulting Agreement is terminated by the Company within the
Option Period for cause, as defined in the Consulting Agreement, the Option
shall thereafter be void for all purposes.

        (b) If Patrick dies, or if Patrick becomes disabled (such that Patrick
is unable to provide the services required under the Consulting Agreement),
during the Option Period or within the three-month period referred to in
Subsection 7(c) hereof, the Option may be exercised by Patrick, or those
entitled to do so under Patrick's will or by the laws of descent and
distribution, as the case may be, within twelve months following Patrick's
death or disability, (provided that such exercise must occur within the Option
Period), but not thereafter. In any such case, the Option may be exercised only
as to the shares of Stock as to which the Option had become exercisable on or
before the earlier of the date of Patrick's death or disability.

        (c) If the Consulting Agreement is terminated within the Option Period
and prior to May 1, 2000 for any reason other than cause, Patrick's disability
or death, the Option may be exercised by Patrick within three months following
the date of such termination (provided that such exercise must occur within the
Option Period), but not thereafter.  In any such case, the Option may be
exercised only as to the shares as to which the Option had become exercisable
on or before the date of early termination of the Consulting Agreement.

     8. Transferability.  The Option may not be transferred by Patrick, except
by will or pursuant to the laws of descent and distribution, and it shall be
exercisable during Patrick's lifetime only by him, or in the event of Patrick's
incapacity, by his guardian or legal 

                                      -6-

representative, and after Patrick's death, only by those entitled to do so
under his will or the applicable laws of descent and distribution.

     9. Miscellaneous.               

        (a) Notices.   Any notice required or permitted to be given under
this Agreement shall be in writing and shall be given by first class registered

        (b) Amendment.   The Company may make any adjustment in the Option
Price, the number of shares of Stock subject to, or the terms of the Option by

substitution may result in terms and conditions (including Option Price, the
number of shares of Stock covered, Vesting Schedule or Option Period) that
differ from the terms and conditions of this Option; however, the Company may
not adversely affect the rights of Patrick without the consent of Patrick.  If
such action is effected by amendment, the effective date of such amendment will

this Agreement may not be amended or otherwise modified unless evidenced in
writing and signed by the Company and Patrick.

        (c) Severability.   The invalidity or unenforceability of any provision
of this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, and each other provision of this Agreement shall

administrators, legal representatives, successors and assigns.

                                 April 30, 1997


Apache Corporation
2000 Post Oak Boulevard
Suite 100
Houston, Texas 77056-4400

Gentlemen:

     I am rendering this opinion in my capacity as Assistant General Counsel of
Apache Corporation, a Delaware corporation ("Apache"), 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 2,092,000 shares of Apache's common stock, $1.25 par value ("Apache
Common Stock"), to be offered under the four plans described in the
Registration Statement (respectively, the "Plans").

     In connection therewith, I have examined the Registration Statement, the
corporate proceedings with respect to the offering of shares and such other
documents and instruments as I have deemed necessary or appropriate for the
expression of the opinion contained herein.

     On the basis of the foregoing, and having regard for such legal
considerations I have deemed relevant, it is my opinion that the 2,092,000
shares of Apache Common Stock to be registered have been duly authorized for
issuance and sale, and when issued in accordance with the terms and conditions
of the Plans, will be legally issued, fully paid and non-assessable.

     I express no opinion as to the laws of any jurisdiction other than the
State of Texas and the General Corporation Law of the State of Delaware.

     I consent to the inclusion of this letter as an exhibit to the
Registration Statement and to the reference in the Prospectus included as part
of the Registration Statement to my having issued the opinion expressed herein.

                                                 Very truly yours,        
                                                                          
                                                 /s/ Eric L. Harry        
                                                                          
                                                 Eric L. Harry            
                                                 Assistant General Counsel
