SECTION 2 - FINANCIAL INFORMATION

Item 2.02.  Results of Operations and Financial Condition
----------  ---------------------------------------------


     On January 24, 2005, Occidental Petroleum Corporation released information
regarding its results of operations for the fiscal period ended December 31,
2004. The exhibits to this Form 8-K and the information set forth in this Item
2.02 are being furnished pursuant to Item 2.02, Results of Operations and
Financial Condition. The full text of the press release is attached to this
report as Exhibit 99.1. The full text of the speeches given by Dr. Ray R. Irani
and Stephen I. Chazen are attached to this report as Exhibit 99.2. Investor
Relations Supplemental Schedules are attached to this report as Exhibit 99.3.



SECTION 8 - OTHER EVENTS

Item 8.01.  Other Events
----------  ------------

     On January 24, 2005, Occidental Petroleum Corporation announced net income
for the fourth quarter 2004 of $665 million ($1.67 per share), compared with
$382 million ($0.99 per share) for the fourth quarter 2003. On January 5, 2005,
Occidental issued a press release announcing that the comparability of fourth
quarter 2004 earnings to prior quarters would be affected by a number of charges
and a tax credit. These items have resulted in net charges totaling
approximately $69 million ($0.17 per share). Record earnings of $2.491 billion
($6.30 per share) for the twelve months of 2004 were 58 percent higher than the
$1.527 billion ($3.98 per share) the company earned in 2003.

                                   Oil and Gas
                                   -----------

     Oil and gas segment earnings were $977 million for the fourth quarter 2004,
compared with $640 million for the fourth quarter 2003, an increase of 53
percent. The improvement in the fourth quarter 2004 earnings reflected higher
worldwide crude oil and natural gas prices, partially offset by higher
exploration expenses and higher operating costs. Oil and gas earnings of $3.544
billion for the twelve months were the highest in the company's history and were
33 percent higher than the $2.664 billion of 2003.

                                    Chemicals
                                    ---------

     Chemical segment earnings were $130 million for the fourth quarter 2004
compared with $72 million for the fourth quarter 2003, an increase of 81
percent. The improvement in the fourth quarter 2004 was due to higher sales
prices in all major products, partially offset by higher ethylene and energy
costs. The fourth quarter 2004 also included the previously announced $12
million charge to write-off certain production facilities. Chemical earnings of
$412 million for the twelve months 2004 were 87 percent higher than the $220
million of 2003.

     Earnings from an equity investment are based on a preliminary estimate of
their earnings.

     See the attached schedules for a reconciliation of net income to core
earnings for the fourth quarter and twelve months.



Statements in this release that contain words such as "will", "expect" or
"estimate", or otherwise relate to the future, are forward-looking and involve
risks and uncertainties that could significantly affect expected results.
Factors that could cause results to differ materially include, but are not
limited to: global commodity pricing fluctuations and supply/demand
considerations for oil, gas and chemicals; higher-than-expected costs; political
risk; and not successfully completing (or any material delay in) any expansion,
capital expenditure, acquisition, or disposition. Occidental disclaims any
obligation to update any forward-looking statements.

(a)  The fourth quarter 2004 includes a $1 million pre-tax interest charge to
     purchase in the open market and retire $32 million of Occidental's senior
     notes. The twelve months 2004 also includes $16 million pre-tax interest
     charges to redeem or repurchase various debt issues during the year. The
     twelve months 2003 includes a $61 million pre-tax interest charge to repay
     a $450 million 6.4 percent senior notes issue that had ten years of
     remaining life, but was subject to re-marketing on April 1, 2003.

(b)  The twelve months 2004 includes a $27 million credit related to a fourth
     quarter settlement and a $20 million credit related to a first quarter
     settlement of issues with the Internal Revenue Service. The twelve months
     2004 also reflected a lower U.S. income tax rate resulting from the
     crediting of foreign income taxes.

(c)  The fourth quarter 2004 includes a $32 million, net of tax, charge reported
     as discontinued operations to reflect Occidental's decision to exit the
     specialty vinyls resins chemical business. Details of the charge are as
     follows:

SIGNIFICANT TRANSACTIONS AND EVENTS AFFECTING EARNINGS

Occidental's results of operations often include the effects of significant
transactions and events affecting earnings that vary widely and unpredictably in
nature, timing, and amount. Therefore, management uses a measure called "core
earnings", which excludes those items. This non-GAAP measure is not meant to
disassociate those items from management's performance, but rather is meant to
provide useful information to investors interested in comparing Occidental's
earnings performance between periods. Reported earnings are considered
representative of management's performance over the long term. Core earnings is
not considered to be an alternative to operating income in accordance with
generally accepted accounting principles.

The following table sets forth the core earnings and significant items affecting
earnings for each operating segment and corporate:
