               Re:  Occidental Petroleum Corporation
                    Registration Statement of Form S-3
                    ----------------------------------

Ladies and Gentlemen:

     I am Associate General Counsel of Occidental Petroleum Corporation, a
Delaware corporation ("Occidental"), and am rendering this opinion in connection
with the preparation of a Registration Statement on Form S-3 (the "462(b)
Registration Statement"), which is to be filed by Occidental on November  , 1998
under Rule 462(b) of the Securities Act of 1933, as amended (the "Securities
Act"), in connection with the Registration Statement on Form S-3 (the "Effective
Registration Statement" and together with the 462(b) Registration Statement, the
"Registration Statement") of Occidental (File No. 333-52053) filed with the
Securities and Exchange Commis  sion (the "Commission") on May 7, 1998.  The
462(b) Registration Statement relates to the registration under the Securities
Act of $70,000,000 aggregate public offering price of senior debt securities
(the "Debt Securities") of Occidental.  The Debt Securities are to be issued
pursuant to an Indenture, dated as of April 1, 1998 (the "Indenture"), between
Occidental and The Bank of New York, a New York banking corporation, as trustee
(the "Trustee").

     This opinion is delivered in accordance with the requirements of Item
601(b)(5) of Regulation S-K under the Securities Act.

     In connection with this opinion, I have examined and am familiar with
originals or copies, certified or otherwise identified to my satisfaction, of
such documents as I have deemed necessary or appropriate as a basis for the
opinions set forth herein, including (i) the 462(b) Registration Statement
(including the documents incorporated therein, including the Effective
Registration Statement and the documents incorporated therein and forming a part
thereof), (ii) the Restated Certificate of Incorporation and By-Laws of
Occidental, in each case, as amended to date, (iii) the Indenture, and (iv)
copies of certain resolutions adopted by the Board of Directors of Occidental
relating to the execution of the Indenture, the issuance of the Debt Securities,
the filing of the Registration Statement and any amendments or supplements
thereto and related matters.  In my examination, I have assumed the genuineness
of all signatures, the legal capacity of natural persons, the authenticity of
all documents submitted to me as originals, the conformity 

 
to originals documents of all document submitted to me as certified, conformed
or photostatic copies and the authenticity of the originals of such copies. As
to any facts material to the opinions expressed herein which I have not
independently established or verified, I have relied upon statements and
representations of officers and other representatives of Occidental and others.

     I am a member of the California and New York Bars and for purposes of this
opinion do not express any opinion as to the laws of any jurisdiction other than
the laws of the State of New York, the Federal laws of the United States and
General Corporation Law of the State of Delaware.  This opinion is limited to
the laws, including the rules and regulations, as in effect on the date hereof.

     Based upon and subject to the foregoing, I am of the opinion that when (a)
the 462(b) Registration Statement becomes effective under the Securities Act;
(b) the appropriate officers of Occidental have taken all necessary action
pursuant to  Section 301 of the Indenture to fix and approve the terms of the
Debt Securities, including the establishment of the form or forms of
certificates  representing the Debt Securities pursuant to Section 201 of the
Indenture; (c) the Indenture pursuant to which the Debt Securities are to be
issued shall have been qualified under the Trust Indenture Act of 1939, as
amended; and (d) the Debt Securities are duly executed and authenticated in
accordance with the provisions of the Indenture and duly delivered to the
purchasers thereof upon payment of the agreed upon consideration therefore, the
Debt Securities will be validly issued and binding obligations of Occidental,
enforceable against Occidental in accordance with their terms, except as may be
subject to or limited by (i) bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect relating to creditors' rights
generally, and (ii) general principles of equity (regardless of whether
enforcement is consider in a proceeding in equity or at law).

     I hereby consent to the filing of this opinion with the Commission as
Exhibit 5 to the 462(b) Registration Statement.  I also consent to the reference
to me under the heading "Legal Matters" in the Registration Statement.  In
giving this consent, I do not thereby admit that I am in the category of persons
whose consent is require under Section 7 of the Securities Act or the rules and
regulations of the Commission.

                         Very truly yours,
