Item 5.  Other Events and Regulation FD Disclosure
------   -----------------------------------------

     On July 22, 2002, Occidental Petroleum Corporation announced net income for
the second quarter 2002 of $240 million ($0.64 per share), compared with $473
million ($1.27 per share) for the second quarter 2001. Earnings before special
items were $466 million ($1.25 per share) for the second quarter 2001. There
were no special items in the second quarter 2002.

     Occidental's net income for the second quarter 2002 of $240 million ($0.64
per share), improved significantly compared with $25 million ($0.07 per share)
for the first quarter 2002, which included a goodwill write off and severance
charges of $104 million after tax. Earnings before special items for the first
quarter 2002 were $129 million ($0.34 per share).

     In announcing the results, Dr. Ray R. Irani, chairman and chief executive
officer, said, "Our second quarter oil and gas production increased by 14
percent compared to last year, with volumes rising from an average of 450,000 to
512,000 barrels of oil equivalent per day. Despite the sharp increase in
production, our profits were down significantly due primarily to much lower gas
prices. We're encouraged by the improvement in our profits compared to the first
quarter. The improvement was driven by higher oil and gas prices and by
strengthening chemical markets for our products. We're on target to increase oil
and gas production by more than 5 percent this year, and we expect production
growth to continue at an average annual rate of 5 percent through 2006 - based
solely on current development projects.

     Our chemical business was aided significantly by improved prices. We expect
additional improvement in the chemical business in the third quarter."

                                   OIL AND GAS
                                   -----------

     Oil and gas segment earnings were $421 million for the second quarter 2002,
compared with $806 million for the second quarter 2001. The decline in the
second quarter 2002 earnings reflected the effect of lower prices of
approximately $400 million, primarily for domestic natural gas, and higher
exploration expense, partially offset by higher production volumes.

     For the first quarter 2002, oil and gas segment earnings were $306 million.
The increase in earnings, in the second quarter 2002 compared with the first
quarter, primarily reflected higher crude oil and natural gas prices, partially
offset by higher exploration expense.

     For the first six months of 2002, production volumes increased
approximately 12 percent to 518,000 barrels of oil equivalent per day (BOE)
compared with 463,000 for the same period of 2001. The increase reflects higher
worldwide crude oil and liquids production, particularly in California, Colombia
and the Middle East.

                                    CHEMICALS
                                    ---------

     Chemical segment earnings were $33 million for the second quarter 2002,
compared with $58 million for the second quarter 2001. The decline in the second
quarter 2002 earnings reflected lower sales prices for caustic soda and PVC,
partially offset by higher EDC prices and lower energy and raw material costs.


                                       2



     The first quarter 2002 segment results after special items were a loss of
$35 million. The improvement in earnings in the second quarter 2002 compared
with the first quarter reflected higher sales prices for chlorine, EDC and PVC
and better performance of our Equistar petrochemical investment, partially
offset by lower caustic soda prices and higher energy and raw material costs.
Core chemical operations, which excludes Equistar, earned $37 million in the
second quarter 2002 compared with $15 million before special items in the first
quarter. Equistar results in the second quarter 2002 improved to a loss of $4
million, compared with a $36 million loss in the first quarter. The sale of
Occidental's Equistar interest to Lyondell is expected to close at the end of
August 2002.

                               SIX MONTHS RESULTS
                               ------------------

     For the first six months of 2002, net income was $265 million ($0.71 per
share), compared with $957 million ($2.58 per share) for the first six months of
2001. Earnings before special items were $369 million ($0.98 per share),
compared with $976 million ($2.63 per share) for the same period of 2001.

     Subsequent to the appointment of KPMG to replace Arthur Andersen as the
Company's independent auditor, KPMG conducted a complete re-audit of
Occidental's consolidated financial statements for the previous three years.
Occidental has filed a 10-K/A with the SEC that contains KPMG's unqualified
report containing no changes in our balance sheet, net income, cash flow or
earnings per share.


     Statements in this presentation that contain words such as "will" or
"expect", 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; 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.

     partners. The second quarter and six months year-to-date 2002 include $8
     million and $22 million, respectively. The second quarter and six months
     year-to-date 2001 include $28 million and $61 million, respectively.
(b)  Includes an offset for (charges)/credits in lieu of U.S. federal income
     taxes allocated to the divisions. Chemical divisional earnings had credits
     allocated to them of $4 million in the second quarter of 2002. The second
     quarter of 2001 was impacted by a ($3) million charge at Oil and Gas and an
     $18 million credit at Chemicals. The 2001 results include a ($4) million
     charge at Oil and Gas related to an asset sale and a $14 million credit at
     Chemicals related to asset sales.
(c)  Includes preferred distributions to the Occidental Permian partners. The
     second quarter and six months year-to-date 2002 include $5 million and $20
     million, respectively. The second quarter and six months year-to-date 2001
     include $28 million and $62 million, respectively. These amounts are

                                  July 22, 2002
                             Los Angeles, California

     Good morning, and thank you for joining us.

     Those of you who haven't received a copy of the press release announcing
our second quarter earnings, along with the Investor Relations Supplemental
Schedules, can find them on our website oxy.com or through the SEC's EDGAR
system.

     Net income was $240 million, or $0.64 per share. There were no special
items last quarter. In last year's second quarter, net income was $473 million,
or $1.27 per share, and earnings before special items were $466 million, or
$1.25 per share.

     For the first half of this year, net income was $265 million, or $0.71 per
share compared to $957 million, or $2.58 per share, during the first half of
2001. Earnings before special items and the effect of changes in accounting
principles during the first half of this year were $369 million, or $0.98 per
share, compared to $976 million, or $2.63 per share last year.

     On a segment basis, oil and gas second quarter earnings were $421 million,
compared to $806 million during the same period a year ago. The decline was due
primarily to lower US natural gas prices.

     The decline was partially offset by a 14 percent increase in oil and gas
production - from 450,000 BOE per day in the second quarter of 2001 to 512,000
barrels this year. For the first half of this year, production was up by 12
percent compared to last year - from 463,000 to 518,000 BOE per day.

     The increases in production in the first half compared to the same period
last year were due to several factors. Domestic liquids production increased by
24,000 barrels per day - with 16,000 barrels of the increase coming from
California. Significantly less downtime on the Cano Limon pipeline resulted in a
24,000 barrels per day increase in Colombia. Finally, a first quarter seasonal
adjustment in the cost recovery volumes related to our production-sharing
contracts in Oman and Yemen added a combined 12,000 barrels per day.

     Chemical segment earnings were $33 million compared to a first quarter 2002
loss of $35. There were no special items in the second quarter. Prices for
chlorine, EDC and PVC have improved and our losses from Equistar declined from a
negative $36 million in the first quarter to a negative $4 million. Earnings
before special items - excluding Equistar - show earnings improving from $15
million in the first quarter to $37 million in the second quarter. The $52
million total for the first half is $23 million more than our core chemical
business earned in the first half of 2001.

     When the deal with Lyondell is closed at the end of August, our third
quarter operations will wind up with two months of Equistar results and one
month of corporate equity earnings based on Lyondell's results. To assist
investors in analyzing our core chemical business, we have included a table that
shows that this business has always made money over the last 10 1/2 years on an
EBIT basis and has always produced positive free cash flow.

     Cash flow from operations for the first half of the year was approximately
$945 million. During the second quarter, we increased shareholder equity by $253
million - which accounts for the reduction in the debt-to-capitalization ratio
from 46 to 45 percent.

     Capital spending for the quarter was $326 million and $600 for the first
half. We expect total spending for the year to be $1.2 billion - with oil and
gas accounting for approximately $1.1 billion.

     Looking ahead in the current quarter, we expect oil and gas production to
remain at roughly the same level as the second quarter. We also expect
additional improvement in chemicals as chlorine, caustic and PVC prices continue
to strengthen.

     Our sensitivity to changes in oil and gas prices will be similar to prior
quarters. The average WTI price in the second quarter was $26.25 per barrel and
our average price realization for natural gas was $2.92 per thousand cubic feet.
A swing of 25-cents per million BTUs in NYMEX gas prices impacts our quarterly
oil and gas segment earnings by $13.5 million while a $1.00 per barrel change in
oil prices has a quarterly impact of $28 million.

     I'd now like to call attention to several balance sheet items.

     When we acquired Altura from the BP-Shell partnership in April 2000, we
recorded $2 billion in long-term receivables and an equivalent amount of
minority interest on our balance sheet. As we said in announcing first quarter
earnings in April, the BP-Shell partnership exercised an option to redeem their
partnership interests in exchange for their minority interest. There was no
impact on the income statement. Both sides of the balance sheet have been
reduced by $2 billion by eliminating the receivable and minority interest.

     In the second quarter, we accrued $310 million to be paid in the third
quarter to the United Arab Emirate's Offset Group as the result of our
successful bid to acquire a 24.5 percent interest in the Dolphin Project.

     Also in the second quarter, Oxy recognized an increase of $82 million in
the value of our 7.7 million shares of Premcor stock. Now that Premcor is
publicly traded, we are required to mark to market the value of our shares each
quarter. This change in value is reflected in the


                                       8



equity account, but no income statement gain would be recognized as long as we
hold the shares as an investment.

     As I said earlier, we expect the sale of our 29.5 percent equity interest
in Equistar and the purchase of 30 to 34 million shares of Lyondell common stock
to close at the end of August. Oxy will recognize an after-tax gain of at least
$100 million that can be viewed as a partial offset to the loss we recorded in
announcing the transaction last December.

     Last March we engaged KPMG to replace Arthur Andersen as the company's
independent auditor. Subsequent to this change, we asked KPMG to conduct a
complete re-audit of our consolidated financial statements for the last three
years. We took this action for two reasons. First, we wanted to assure investors
that our financial statements were accurate. Second, we were concerned that no
one would be available from Arthur Andersen to sign consents or stand behind the
statements.

     Upon the completion of KPMG's audit, we filed a 10-K/A with the SEC last
Friday which contains KPMG's unqualified report on our financial statements. The
new filing contains no changes in our balance sheet, net income, cash flow or
earnings per share. The only modifications made in connection with the re-audits
are to update the Management and Discussion Analysis and the Notes to the
Financial Statements to incorporate accounting pronouncements and events that
have transpired since the original filing date. Furthermore, KPMG made no
recommendations to management or the Audit Committee for any changes. Our
financial statements remain the same.

     Now we're ready to take your questions. Joining me this morning are Oxy's
chairman and CEO, Dr. Ray Irani, and president, Dr. Dale Laurance.

CHLORINE
--------
OXYCHEM COMMENTARY
------------------
o    Demand for chlorine continued to improve through the 2nd quarter of 2002.
     Industry operating rates climbed further, driven by the improved demand and
     capacity curtailments. Rates have improved from a low of 77% in December
     2001, to 87% in the 1st quarter 2002 and 92% in the 2nd quarter.
     Expectations are that demand will continue to improve in the 3rd quarter.

o    The supply of chlorine continues to be very tight. Many producers are
     having trouble meeting contract obligations leaving very little product
     available for the spot market.

o    The improved supply/demand situation has led to improved prices. The 1st
     quarter announced $50/ton increase was implemented in April. An additional
     increase of $125/ton was announced in late May with implementation expected
     in July.

INFLUENCING FACTORS:
--------------------

Continued demand improvement requires sustained economic recovery. With no new
capacity additions being announced, operating rates will improve as economic
conditions


                                       20

improve. Stronger demand and higher operating rates will support additional
price increases in the long-term.

CAUSTIC
-------
OXYCHEM COMMENTARY
------------------
o    Caustic soda demand in domestic and export markets, while still
     fundamentally flat, is beginning to show some signs of recovery. Caustic
     soda consumption in the Pulp and Paper business, a key market for liquid
     caustic soda, is beginning to recover. Demand into the distribution market
     as well as the inorganic and organic chemicals marketplace is also showing
     some signs of recovery. Demand is expected to strengthen further in the 2nd
     half.

o    Domestic pricing continued to weaken in the 2nd quarter with prices
     bottoming out in May. A $50/ton price increase was announced in mid-May and
     has been supported by the industry.

INFLUENCING FACTORS:
--------------------

Caustic soda demand is closely tied to overall economic activity and the health
of the US manufacturing sector. Traditionally caustic soda demand lags the
recovery of its co-product chlorine by several months. Chlorine demand has
already recovered and the supply/demand balance for caustic soda is shifting,
which is expected to lead to price recovery for caustic soda.

EDC
---
OXYCHEM COMMENTARY
------------------
o    Demand continued to improve through the 2nd quarter while supply has been
     extremely tight worldwide. Exports to Asia have declined due to a recent
     drop in PVC prices in China and higher EDC inventories in China. Overall
     demand may decline slightly in July but is expected to rebound by the
     August/September timeframe.

o    Pricing increased rapidly through the second quarter as buyers scrambled to
     secure available product. Market prices in May were almost 7 cents/lb
     higher than in March and 13 cents/lb higher than in January.

INFLUENCING FACTORS:
--------------------
EDC remains in short supply, which continues to drive prices upward. Although
recent declines in PVC prices in China have created some short-term downward
pressure, demand is expected to rebound again.

PVC/VCM
-------
OXYCHEM COMMENTARY
------------------
o    PVC resin demand outweighed production capability through the second
     quarter and resin inventories continued to decline. The tightness of the
     market is due to seasonal increases in demand, low beginning inventories
     and a moderate export market.
o    OxyVinyls' PVC operating rates for the 2nd quarter improved to 98%. Rates
     in the 3rd quarter are expected to remain at this level. The estimated
     industry average operating rate for the 2nd quarter was 94% as some
     producers were constrained by a lack of chlorine. Capacities have been
     modified to exclude both the Borden Geismar and the former Borden Addis
     facilities, which are currently idle.
o    Domestic PVC resin prices increased $.02/lb in April, $.02/lb in May, and
     $.04/lb in June. Further increases of $0.02/lb have been announced for July
     and August.
o    U.S. export PVC resin prices into Asia peaked at the end of May at $700/MT,
     up from $580/MT in March but declined to $580/MT in June as purchases from
     China decreased. Prices to Latin America held at $720 - $750/MT.
o    Strong demand for VCM continued through the 2nd quarter and it is expected
     to remain strong through the balance of the year. VCM inventory levels
     remain very low due to strong domestic PVC demand and numerous planned and
     unplanned plant outages. More outages are scheduled for the 3rd quarter,
     which should keep inventory levels low.
o    Demand for VCM overseas remains strong in Mexico and Latin America. Asian
     demand has fallen due to reduced PVC demand in China but is expected to
     improve. Export demand is expected to remain strong into the 3rd quarter as
     several maintenance shutdowns in Europe and Asia have kept inventories at
     low-to-moderate levels.
o    Export VCM pricing started the year in the $250-$260/MT range but increased
     to $440 -$460/MT at the end of the 1st quarter and has increased further to
     the $500-$520/MT range for June shipments. Pricing for July shipments is
     expected to be in the $500-$540/MT range.

INFLUENCING FACTORS:
--------------------
Normal seasonal downturns in the 2nd half PVC market will be strongly moderated
by a tight VCM market, idled PVC plants, and very low VCM and PVC inventories.
