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

     On October 17, 2001, Occidental Petroleum Corporation announced earnings
before special items for the third quarter 2001 of $317 million ($0.85 per
share), compared with $370 million ($1.00 per share) for the same period a year
ago.

     In announcing the results, Dr. Ray R. Irani, chairman and chief executive
officer, said, "The strong third quarter performance of our oil and gas segment
and the profitability of our chemical segment, despite the slowing economy, has
kept us on track for another record year. Our earnings before special items, of
$1.3 billion, or $3.48 per share, through the first three quarters nearly
equaled our record performance for the entire year 2000. The combination of
strong cash flow from operations and proceeds from non-strategic asset sales has
resulted in substantial debt reduction that, along with outstanding earnings,
has enabled us to slash our debt-to-capitalization ratio to 46-percent, the
lowest level in nearly two decades."

     Net income for the third quarter of 2001 was $444 million ($1.19 per
share), compared with $402 million ($1.09 per share) for the same period of
2000. The third quarter 2001 included the sale of non-strategic assets,
including Occidental's interest in the Tangguh LNG project in Indonesia and the
sale of the entity that leased a pipeline in Texas to Occidental's former MidCon
subsidiary for after-tax cash proceeds of $750 million, resulting in a net
after-tax gain of $127 million. The third quarter 2000 included net after-tax
gains of $31 million.


                                 Debt Reduction
                                 --------------

     During the third quarter, the $750 million in after-tax proceeds from the
Indonesia and pipeline asset sales, combined with free cash flow from
operations, lowered Occidental's total debt to $5.0 billion, compared to $6.4
billion at the end of 2000 and the pro-forma peak of $9.2 billion in April 2000.
The reduced debt level, along with the drop in interest rates, lowered interest
expense (including distribution on trust preferred securities) to $98 million
from $113 million for the second quarter 2001 and $152 million for the third
quarter of 2000.


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

     Oil and gas segment earnings before special items were $528 million for the
third quarter 2001, compared with $690 million for the same period in 2000. The
decline in earnings is primarily due to lower worldwide crude oil prices and
higher exploration expense. The third quarter 2001 exploration expense included
the write-off of the Gibraltar well in Colombia.

     Oil and gas segment earnings for the third quarter 2001 were $927 million
and included the $399 million gain, net of tax, from the sale of the Tangguh LNG
project. Third quarter 2000 oil and gas earnings were $696 million, including
net gains of $6 million from special items.


                                    Chemicals
                                    ---------

     Earnings from the chemicals segment were $40 million for the third quarter
2001, compared with $47 million for the third quarter 2000. The results reflect
improvements in those chemicals

                                       1


businesses operated by the company that were more than offset by significantly
lower earnings from our petrochemical equity investment.


                               Nine Months Results
                               -------------------

     For the first nine months of 2001, Occidental's earnings before special
items increased 31-percent to $1.3 billion ($3.48 per share), compared with $977
million ($2.65 per share) for the same period of 2000. Net income was $1.4
billion ($3.77 per share) for the first nine months of 2001, compared with $1.2
billion ($3.36 per share) for the first nine months of 2000. Sales rose by
approximately 20-percent to $11.6 billion for the first nine months of 2001,
from $9.6 billion for the same period a year ago.


Forward-looking statements and estimates regarding exploration and production
activities, oil, gas and commodity chemical prices and their related earnings
effects, and cost reductions, as well as pro-forma estimates in this release are
based on assumptions concerning market, competitive, regulatory, environmental,
operational and other conditions. Actual results could differ materially as a
result of factors discussed in Occidental's Annual Report on Form 10-K.

     million and $68 million, respectively.

(b)  Includes an offset for charges and credits in lieu of U.S. federal income
     taxes allocated to the segments. Oil and gas segment earnings have been
     impacted by charges of $35 million and $42 million in the third quarters of
     2001 and 2000, respectively. The oil and gas segment third quarter of 2001
     includes the tax effects from the sale of its interest in the Tangguh LNG
     project in Indonesia. The oil and gas segment third quarter of 2000 amount
     includes the tax effects from the partial-interest sale of the subsidiary
     that owned the Gulf of Mexico shelf assets and receipt of contingency
     payments related to a prior year sale of a Dutch North Sea subsidiary.
     Chemical segment earnings have been impacted by credits of $16 million in
     the third quarter of 2001, $12 million of which related to asset
     dispositions, and $4 million in the third quarter of 2000.

                    Third Quarter 2001 Earnings Announcement

                                October 17, 2001
                               New York, New York

     Good morning, and thanks for joining us.

     Most, if not all, of you have already received a copy of the press release
announcing our third quarter earnings along with the Investor Relations
Supplemental Schedules. If you haven't received them, you can find them on our
website, oxy.com, or on the SEC's EDGAR site.

     Earnings before special items were $317 million, or $0.85 per share,
compared with the $370 million, or $1.00 per share, we earned in the third
quarter last year.

     For the first nine months of this year, earnings before special items were
$1.3 billion, or $3.48 per share, a 31-percent increase compared to $977
million, or $2.65 per share last year.

     On a segment basis, oil and gas third quarter earnings before special items
were $528 million, compared to $690 million during the same period a year ago.
This decline is due primarily to lower worldwide crude oil prices and higher
exploration expense.

     Oil prices for the quarter averaged $22.61 per barrel compared to $27.26
during the same period last year. Natural gas prices in the US for the quarter
averaged $4.59 per MCF versus $4.18 during last year's third quarter. The
premium for our California gas was approximately $2.70 per MCF above NYMEX.
Looking forward to the fourth quarter, we expect this premium to disappear. The
loss of this premium is expected to reduce our fourth quarter segment earnings
by $70 million compared with the third quarter. In addition, a $1.00 per million
BTUs swing in NYMEX gas prices has a $62 million impact on our quarterly oil and
gas earnings, and a $1.00 per barrel change in oil prices will impact quarterly
earnings by $28 million. The fourth quarter usually is the weakest period for
gas prices since it represents production from the low gas storage injection
months of September, October and November that fall between the summer air
conditioning and winter heating seasons. Gas prices during the period are
generally set at the beginning of each of these months.

     Although third quarter oil and gas earnings before special items were lower
than the second quarter mainly because of significantly lower natural gas
prices, the effect was partially offset by improved oil production, primarily
from Colombia. Worldwide oil production increased from 341,000 barrels per day
in the second quarter to 384,000 barrels in the third quarter. Approximately

                                       6


65-percent of Oxy's BOE production is in the US with 10-percent in Latin America
and 25-percent in the Eastern Hemisphere.

     Exploration expense was $91 million in the quarter compared to $43 million
in last year's third quarter. Included in this year's exploration expense is the
write-off of the Gibraltar well in Colombia that accounted for $66 million of
the total.

     Chemical earnings before special items were $40 million compared to $47
million in last year's third quarter. The decline primarily reflects worsening
results from our petrochemical equity interest. The industry as a whole is
operating on approximately a cash break-even basis.

     In Oxy's operations, lower prices for our products were more than offset by
lower energy, feedstock and overhead costs.

     The fundamental weakness in chemical demand we discussed last quarter is
continuing with no signs of an early recovery.

     Cash flow from operations for the first nine months of the year was
approximately $2.3 billion. For the first nine months we increased shareholder
equity by approximately $1.1 billion to $5.9 billion. At the same time, we
reduced total debt by over $1.3 billion to $5.0 billion, compared to just under
$6.4 billion at the end of last year. During the quarter, we received $750
million in after-tax proceeds from the sale of Oxy's interest in the Tangguh LNG
project in Indonesia and the sale of the entity that leased a pipeline in Texas
to Oxy's former MidCon subsidiary.

     At the end of the third quarter our debt to total capitalization ratio was
down to 46-percent, compared to 57-percent at the end of last year. We expect
further improvement in this ratio in the fourth quarter. Interest expense,
including distributions on trust preferred securities, was $98 million during
the third quarter this year compared to $152 million in last year's third
quarter and $113 million in the second quarter this year. Through the first nine
months of this year, total interest expense of $337 million is $81 million below
the same period a year ago.

     Capital spending for the quarter was $418 million and $965 million for the
first nine months. We expect total spending for the year of $1.4 billion,
including $100 million for chemicals.

     Now I'd like to turn the conference call over to Dr. Ray Irani, Chairman
and CEO.

    Text of Speech by Dr. Ray R. Irani, Chairman and Chief Executive Officer
    ------------------------------------------------------------------------

                        Occidental Petroleum Corporation

                                DR. RAY R. IRANI
                      Chairman and Chief Executive Officer

                               - Conference Call -
                    Third Quarter 2001 Earnings Announcement

                                October 17, 2001
                               New York, New York

     Thank you, Steve.

     As Steve reported, we completed the best nine-month period in the company's
history. When we reported our second quarter results in July, we said our
balance sheet would continue to grow stronger in the second half of the year as
we remained focused on rapidly reducing our debt. Our debt to capitalization
ratio was cut from 51-percent at the end of the second quarter to 46-percent, as
we reduced debt by $862 million during the third quarter.

     The substantial progress we've made in materially improving our balance
sheet and the continued strengthening of our oil and gas asset base have led
both Standard and Poor's and Moody's to upgrade the company's debt ratings in
the third quarter.

     The considerable de-leveraging we've achieved over the past 18-months
contrasts sharply to almost all our competitors. By focusing on maximizing the
benefits from high energy prices and the timely disposition of non-strategic
assets to bolster our balance sheet, we've increased our financial flexibility,
reduced our earnings volatility and significantly strengthened our capacity to
weather downward pressure on energy and chemical prices in a slumping economy.

     A comparison of last year's total interest expense of $554 million with our
annualized third quarter 2001 interest expense of $392 million, shows a savings
of $162 million that equates to an improvement of 28-cents a share in our bottom
line.

     Despite the tragic events of September 11th, our worldwide oil and gas
operations have been carrying on with business as usual. Production has not been
affected. Significantly, the US accounts for approximately 55-percent of our
worldwide oil production and 92-percent of our natural gas production. On a BOE
basis, nearly two-thirds of our worldwide production comes from US operations.
Our proven oil and gas reserves also are mainly in the US. The US holds
75-percent of our worldwide oil reserves and 95-percent of our gas reserves, or
approximately 78-percent of our proven reserves on a BOE basis.

     The Middle East countries of Qatar, Oman, Pakistan and Yemen account for
about 20-percent of our worldwide production on a BOE basis, with Yemen making
up 6-percent of the total and Pakistan about 3-percent. Significantly, our
producing operations in Yemen were never interrupted during the civil war in the
mid-1990s. The same can be said for Pakistan where we've had producing
operations for more than two decades that have never been impacted by shifts in
the country's internal politics.

                                       8


     The investment climate in Oman and Qatar is excellent, and we maintain
exceptionally strong relations with the leaders of both countries. I had the
opportunity to meet personally once again with the Emir of Qatar, His Majesty,
Sheikh Hamad Bin Khalifah Al-Thani, during his recent trip to the US. The Emir
is very pleased with our performance in enhancing oil production from Qatar's
North and South Dome oil fields and he was also pleased to learn of our plans to
increase our level of investment to further boost oil production.

     The Saudi Arabian natural gas project is moving ahead. We, along with our
partners, are working closely with the Saudi Negotiating Team and Aramco to
assure the success of this important project.

     Finally, I recently returned from a trip to the United Arab Emirates where
I had a series of productive meetings with key leaders regarding new business
opportunities. Occidental was one of five western oil companies, including
British Petroleum, Exxon, Shell and Conoco, short-listed to compete for a
25-percent interest in the Dolphin Project.

     The Dolphin Project involves delivery of 2 billion cubic feet per day of
natural gas from Qatar's North Field to markets in the UAE through a sub-sea
pipeline. We're very pleased to be in the running for this project which is
scheduled for start-up in late 2004 or early 2005.

     Thank you - and we're now ready to answer questions.

United States: US Other natural gas production is down due to the sale of a
partial interest in the Gulf of Mexico assets in the third quarter of last year.

Latin America: The decline in Ecuador's production is a result of a farm out of
40 percent of Occidental's interest to Alberta Energy Company in the fourth
quarter of last year.

CHLORINE
--------
OXYCHEM COMMENTARY
------------------
o    Demand for chlorine remains weak and is not expected to improve in the 4th
     quarter. Chlorine to EDC is expected to remain significantly below 2000
     levels although some improvement in the 4th quarter is expected because
     inventory levels have been reduced substantially.

o    Prices are expected to continue their gradual decline throughout the 4th
     quarter as total demand weakens.

INFLUENCING FACTORS:
--------------------
Overall chlorine demand is lackluster and demand in West Europe is weak. Demand
for chlorine going into the vinyls sector has not improved. However, there are
some early indications that demand for chlorine derivatives in the Far East may
be picking up and prices are expected to increase.

CAUSTIC
-------
OXYCHEM COMMENTARY
------------------
o    The slowdown in economic activity has contributed to a slight oversupply
     and operating rates remain low.

                                       20


o    Pricing is expected to soften through the 4th quarter due to continued
     downward pressure on demand.

INFLUENCING FACTORS:
--------------------
The U.S. and global economic slowdown has weakened caustic soda demand and will
continue the downward pressure on prices.

EDC
---
OXYCHEM COMMENTARY
------------------
o    Demand in general is expected to remain weak. Total sales for 2001 are
     expected to be the lowest since 1991.

o    Pricing continues to come under pressure due to weak demand and oversupply.

INFLUENCING FACTORS:
--------------------
Lower demand into the export vinyls market continues to soften prices, although
they are expected to increase slightly in the 4th quarter as demand in Asia
improves.

OXYCHEM COMMENTARY
------------------
o    PVC resin demand remained weak but steady through the 3rd quarter until the
     second half of September when orders declined. PVC resin inventories, as
     well as downstream customer inventories, remained at very low levels. An
     increase in demand, which could occur as early as the 1st quarter 2002 in
     anticipation of a rebound in the economy, may result in supply problems as
     customers struggle to rebuild inventories.

o    Domestic PVC resin prices deteriorated through the 3 rd quarter, down from
     a current year high in April 2001. This decline in revenue has been
     partially offset by lower feedstock and energy costs.

o    Domestic demand for VCM is weaker than previous quarters. Despite outages
     at Dow, OxyVinyls, Formosa, and Georgia Gulf, VCM supply capability
     continues to outpace current demand. Outages in Europe have resulted in an
     outlet for some of the excess. VCM shipments from the U.S. have increased
     as netbacks have improved recently.

INFLUENCING FACTORS:
--------------------
Prices will remain under pressure due to excess capacity and economic
uncertainty. Feedstock price declines have helped to stabilize depressed
margins.
