                            EXPLANATORY STATEMENT

     Pursuant to this Post-Effective Amendment No. 2 to its Registration
Statement on Form S-3 (Registration Number 333-21019)(the "Registration
Statement"), Occidental Petroleum Corporation deregisters all shares of
its common stock, $.20 par value per share, not heretofore deregistered
and not previously sold, including those additional shares which became
subject to the Registration Statement in February 1997 and are referred to
herein as the Adjustment Shares. The reason for deregistration is that all
shares which were registered became tradable pursuant to Rule 144 under the
Securities Act of 1933, as amended, on August 30, 1997, or in the case of
Adjustment Shares, which amount to only 118,275 shares, January 9, 1998. All
shares are now being deregistered. The Registration Satement shall have no
further force or effect.
