                    SECOND QUARTER 2004 EARNINGS ANNOUNCEMENT

                                  JULY 19, 2004
                             Los Angeles, California


     Good morning, and thank you for joining us.

     If you would like a copy of the press release announcing our second quarter
earnings, along with the Investor Relations Supplemental Schedules, you can find
them on our website www.oxy.com or through the SEC's EDGAR system.

     Reported and core earnings for the second quarter were $ 581 million, or
$1.48 per share, compared with $374 million, or $0.98 per share in the second
quarter of 2003. The improvement was driven mainly by higher energy prices and
increased oil and gas production.

     o    Oil and gas production for the quarter averaged 574,000 barrels of oil
          equivalent per day compared to 544,000 barrels in last year's second
          quarter. For the first half of this year, worldwide production was up
          by 6 percent compared to last year - from 538,000 to 571,000 BOE per
          day.

     For the first half of this year, core earnings were $1.06 billion, or $2.69
per share compared to $807 million, or $2.12 per share, during the first half of
2003.

     On a segment basis, oil and gas second quarter earnings were $814 million,
compared to $637 million during the same period a year ago. As I


                                       1



noted earlier, the increase was due primarily to higher prices and increased
production, partially offset by higher operating expenses and increased DD&A
rates.

     Chemical segment earnings were $85 million compared to second quarter 2003
earnings of $43 million. Higher prices for vinyl chloride monomer, polyvinyl
chloride, ethylene dichloride and chlorine contributed to improved margins that
were partially offset by higher energy and feedstock costs. Our core chemical
business earnings of $135 million for the first half compares to last year's
first half earnings of $78 million. Included in last year's second quarter
chemical results was $15 million in severance expenses resulting from a
significant reorganization of our chemical business that was focused on reducing
overhead as well as a $9 million write-off of certain assets at a chemical
plant.

     We reduced our debt-like obligations during the quarter by $360 million by
discontinuing the sale of an interest in our outstanding accounts receivable
balance. This action reduced our cash flow from operations for the first half of
the year from approximately $1.8 billion to $1.4 billion.

     Discontinuing the sale of the receivables, together with the first quarter
redemption of our share of the debt for the Elk Hills power plant and $453
million of trust preferred securities, has reduced our obligations since the
beginning of the year by just over a billion dollars.

     Our net interest expense, including the trust preferred distributions,
declined to $60 million for the quarter and $128 million for the first half
compared to $64 million and $199 million for the comparable periods last year.

     At the end of the quarter, stockholders' equity had grown to $9 billion,
and our debt to capitalization ratio was down to 31 percent compared


                                       2



to 37 percent at the end of last year. We had $383 million of cash on the
balance sheet at the end of the quarter.

     Capital spending for the quarter was $461 million and $804 million for the
first half - with oil and gas accounting for more than 90 percent of the
expenditures.

     As we look ahead in the current quarter:

     o    We expect oil and gas production to remain at about the same level as
          the second quarter.

     o    We expect exploration expense for the quarter to be about $45 million.

     o    We see the upturn in chemical markets continuing in the third quarter.
          We expect some margin improvement as well as high utilization rates.
          Therefore, we expect third quarter chemical earnings to be in the $100
          million range, compared to $85 million in the second quarter.

     o    We expect third quarter interest expense to be approximately the same
          as the second quarter.

     o    A $1.00 per barrel change in oil prices impacts segment annual
          earnings by about $138 million, before the effect of foreign income
          taxes. The average WTI price in the second quarter was $38.32 per
          barrel. A swing of 10-cents per million BTUs in gas prices has a $5
          million impact on quarterly oil and gas earnings. The NYMEX gas price
          for the second quarter was $5.79 per million BTUs. Our average
          realized price for the second quarter was $4.26, and we expect our
          realized price for the third quarter to be about $4.90.


                                       3



     o    Our worldwide effective tax rate for the second quarter was 40
          percent. The second quarter reflects a lower U. S. income tax rate
          resulting from the crediting of foreign income taxes. Previously,
          foreign income taxes were taken as a deduction from U. S. income
          taxes. U. S. taxpayers may elect annually to apply whichever method is
          more beneficial. The effect of this change resulted in an improvement
          of approximately 8 cents per share in second quarter earnings. We
          expect to make this election every year from now on. This will not
          only result in improved earnings for the remainder of 2004, but in
          future years. We expect the rate for the rest of this year to be about
          40 percent. Both our U. S. and foreign tax rates are included in the
          "Investor Relations Supplemental Schedule" which has been modified to
          reflect the effect of this tax election.

     o    We record the equity earnings from our investment in Lyondell Chemical
          Company in corporate "Other". We currently own about 41 million
          Lyondell shares. We have no way of forecasting the quarterly equity
          earnings from our Lyondell investment, although the outlook for the
          business appears to be favorable.

     Now we're ready to take your questions.
