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

     On July 19, 2001, Occidental Petroleum Corporation announced earnings
before special items for the second quarter 2001 of $466 million ($1.25 per
share), up 34-percent from $343 million ($0.93 per share) for the same period a
year ago.

     In announcing the results, Dr. Ray R. Irani, chairman and chief executive
officer, said, "Strong energy prices, particularly in California's natural gas
market, resulted in outstanding earnings and cash flow for the second quarter
and the first half of this year. The chemical segment returned to profitability
in the second quarter after experiencing losses for the previous two quarters.
During the first half of the year, Occidental's earnings before special items of
$976 million, or $2.63 on a per share basis, were the highest in the history of
the company for any six-month period. We have used our free cash flow to reduce
debt by approximately $480 million during the first six months, raising the debt
reduction total to nearly $3.3 billion from our pro-forma peak debt of $9.2
billion in April 2000. Our debt to capitalization ratio at the end of June was
51-percent. Over the past week we announced the sale of our interest in the
Tangguh LNG project in Indonesia and the sale of the entity that leased a
pipeline in Texas to our former MidCon subsidiary. These two transactions will
provide an additional $750 million in after-tax net proceeds for debt reduction,
which would increase our total debt reduction so far this year to $1.23 billion.
We expect to have additional and significant debt reduction during the balance
of this year, and debt reduction will remain a high priority next year."

     Net income was $473 million ($1.27 per share), compared with $564 million
($1.53 per share) for the same period last year. The second quarter 2001
included a $7 million gain, net of tax, related to the sale of additional
interests in the Gulf of Mexico. The second quarter 2000 included an after-tax
gain of $300 million related to the sale of an investment in Canadian Occidental
Petroleum Ltd. and an after-tax charge of approximately $79 million for the
write-down of chemical intermediates businesses. Sales increased 19-percent to
$3.8 billion in the second quarter of 2001, from $3.2 billion for the same
period a year ago.


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

     During the quarter, total debt was reduced by $244 million, lowering total
debt at the end of the quarter to $5.9 billion and reducing the debt to
capitalization ratio to 51-percent. Interest expense (including distributions on
trust preferred securities but excluding interest income received on notes
receivable from Occidental Permian partners) was $113 million for the second
quarter of 2001, compared with $150 million for the second quarter of 2000. The
decline is primarily a result of the significant debt reduction over the last
twelve months.

     If the Tangguh LNG and pipeline entity sales had occurred in the second
quarter, total debt on a pro-forma basis would have been reduced to $5.1
billion, with an implied debt to capitalization ratio of 48-percent.


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

     The oil and gas segment earnings before special items were $799 million for
the second quarter 2001, compared with $557 million for the second quarter 2000.
The improvement in earnings is primarily the result of higher domestic natural
gas prices, partially offset by lower worldwide crude oil prices and lower crude
oil volumes primarily in Colombia. The California gas market price

                                       1


premium remained strong in the second quarter 2001, resulting in an average
domestic gas price of $8.55 per thousand cubic feet.

     Oil and gas segment earnings for the second quarter 2001 were $806 million
and included the $7 million gain, net of tax, discussed above.


                                   Chemicals
                                   ---------

     The chemicals segment earnings before special items were $58 million for
the second quarter 2001, compared with $154 million for the second quarter 2000.
The decline in earnings before special items reflects lower sales prices for
PVC, EDC and chlorine, lower earnings from equity affiliates and higher energy
costs, partially offset by higher prices for caustic soda. The earnings in the
second quarter 2001, compared with losses in the previous two quarters, reflect
lower energy and feedstock costs and the results of aggressive overhead
reduction efforts.

     Chemical segment earnings also were $58 million for the second quarter 2001
compared to $34 million for the second quarter 2000 that included a $120 million
pre-tax charge for the write-down of chemical intermediates businesses.


                               Six Months Results
                               ------------------

     For the first six months of 2001, Occidental's earnings before special
items were $976 million ($2.63 per share), compared with $607 million ($1.65 per
share) for the same period of 2000. Net income was $957 million ($2.58 per
share) for the first six months of 2001, compared with $835 million ($2.27 per
share) for the same period of 2000. Sales increased by approximately 43-percent
to $8.3 billion for the first six months of 2001, from $5.8 billion for the same
period of 2000.



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.

(a)  The second quarter and six months year-to-date 2001 include $28 million and
     $61 million, respectively, interest income on notes receivable from
     Occidental Permian partners. Comparable amounts for 2000 were $30 million
     for both the second quarter and six months year-to-date.

(b)  Includes an offset for (charges)/credits in lieu of U.S. federal income
     taxes allocated to the divisions. Divisional earnings have been impacted by
     a ($3) million charge at Oil and Gas and an $18 million credit at Chemicals
     in the second quarter of 2001. The second quarter of 2000 had credits
     allocated to the divisions of $2 million and $4 million at Oil and Gas and
     Chemicals, respectively. 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. Additionally, the 2000 results include the tax
     related to the gain on the sale of Canadian Occidental Petroleum Ltd. in
     April 2000. The gain is reflected in Unallocated Corporate Items - Other.

(c)  Includes preferred distributions to the Occidental Permian partners. The
     second quarter and six months year-to-date 2001 include $28 million and $62
     million, respectively. The second quarter and six months year-to-date 2000
     include $30 million. These amounts are essentially offset by the interest
     income discussed in (a) above. Additionally, the 2000 results include the
     pre-tax gain of $493 million related to the sale of the investment in
     Canadian Occidental Petroleum Ltd.

                    Second Quarter 2001 Earnings Announcement

                                  July 19, 2001
                             Los Angeles, California

     Good morning, and thanks for joining us.

     Most, if not all, of you have already received a copy of the press release
announcing our second 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 $466 million, or $1.25 per share, That's
a 34-percent increase above the $343 million, or 93 cents per share, we earned
in the second quarter last year.

     For the first half of this year, earnings before special items were $976
million, or $2.63 per share, compared to $607 million, or $1.65 per share last
year. These are the highest earnings for any six-month period in the company's
history.

     On a segment basis, oil and gas second quarter earnings before special
items were $799 million, compared to $557 million during the same period a year
ago. This improvement is due primarily to higher natural gas prices.

     Our average domestic natural gas price realizations were approximately
three times higher this year at $8.55 per thousand cubic feet compared to $2.81
in the same quarter last year. The primary driver behind higher gas prices was
the premium of approximately $8.00 per million BTUs above the average NYMEX
price we received for our California gas production. Looking ahead, we are
experiencing a softening of California natural gas prices and a narrowing of the
differential to about $2.50 per thousand cubic feet. We expect our average third
quarter California gas price realization to remain well above the NYMEX for the
same period. We produce about 300 million cubic feet per day in California and a
differential of one-dollar equates to $27 million in quarterly oil and gas
earnings.

     Increased natural gas prices more than offset the decline in oil price
realizations during the second quarter. Oil prices for the quarter averaged
$23.02 per barrel compared to $24.69 during the same period last year. A $1.00
per million BTUs swing in NYMEX gas prices has a

                                       6


$62 million impact on our quarterly oil and gas earnings. Likewise, a $1.00 per
barrel change in oil prices will impact quarterly earnings by $28 million.

     A number of factors accounted for the decline in production compared to the
same period a year ago, with the primary factor being the shut-in of Colombian
production for the entire quarter due to a pipeline outage. Our Colombian
operation produced an average of 44,000 barrels of oil per day during the second
quarter last year. We also sold properties in the Gulf of Mexico that
contributed 113 million cubic feet per day of gas production in the second
quarter last year.

     The impact of these events was partially offset by the addition of
production from the former Altura properties we purchased in late April last
year.

     Turning to Qatar. What appears on the surface to be a 20,000-barrel per day
decline in our Qatar production is due primarily to a timing issue surrounding
cargo shipments. Last year, we had an extra cargo in the second quarter while
this year we had one less than normal.

     Exploration expense was $18 million in the quarter compared to $15 million
in last year's second quarter and $21 million in this year's first quarter. Our
spending rate remains well below trend, but in the current quarter we expect to
have the results from the drilling of two major wells, for a total estimated
investment of $70 million.

     Chemical earnings before special items were $58 million compared to $154
million in last year's second quarter. The year-to-year decline reflects lower
prices for most of our products, lower earnings from our equity interest in
Equistar and higher energy costs, partially offset by higher caustic soda
prices. During the first quarter this year, we reported a loss of $53 million.
The sequential quarterly improvement is due to reduced energy and feedstock
costs and lower overhead. Last quarter we took a severance charge as part of our
ongoing efforts to cut costs and the benefits of those actions are beginning to
flow through.

     The fundamental weakness in chemicals demand we discussed last quarter is
continuing, but it's encouraging that the inventory liquidations we saw over the
last several quarters appears to be over. However, a meaningful recovery
continues to depend on a strengthening of the economy.

     Cash flow from operations during the first half of the year was
approximately $1.3 billion. During the second quarter we increased shareholder
equity by $453 million. At the same time, we reduced total debt by $244 million
to under $5.9 billion, compared to just under $6.4 billion at the end of last
year. We expect to continue using our free cash flow to pay down debt. I want to
remind everyone that our calculation of total debt includes preferred
securities, the Altura non-recourse debt, Oxy's corporate debt and other
obligations.

     At the end of the quarter our debt to total capitalization ratio was down
to 51-percent, compared to 57-percent at the end of last year. Interest expense,
including distributions on trust preferred securities, of $113 million during
the second quarter this year is $37 million less than last year's second
quarter. Through the first six months of this year, total interest expense of
$238 million is $28 million below the same period a year ago.

                                       7


     Yesterday, we announced the sale of our residual interest in Occidental
Texas Pipeline Company to Kinder Morgan Inc. for $360 million. We had retained
this interest as part of the sale of MidCon in 1998. In the current interest
rate environment, we had an opportunity to monetize our interest in this
non-core asset. This transaction follows last week's announcement of the sale to
Mitsubishi of our interests in the Tangguh LNG project in Indonesia for $480
million. The combined after-tax proceeds from these two transactions provide a
total of $750 million for additional debt reduction which is equivalent to about
one year's free cash flow in a typical year. Thus the proceeds from these sales
have allowed us to accelerate our debt reduction program by about one year.

     The two transactions will generate a combined after-tax gain of $125
million in the third quarter. The Tangguh sale has closed while the pipeline
sale will close later in the year.

     If these transactions had occurred in the second quarter, our total debt on
a pro-forma basis would have been $5.1 billion, with an implied debt to
capitalization ratio of 48-percent. Debt reduction remains a high priority for
the remainder of this year and in 2002.

     Last week, Standard & Poor's and Moody's both announced that they were
reviewing our credit rating for possible upgrades.

     Capital spending for the quarter was $309 million and $547 for the first
half. We expect total spending for the year of $1.3 billion, including $100
million for chemicals.

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

                        Occidental Petroleum Corporation

                                DR. RAY R. IRANI
                      Chairman and Chief Executive Officer

                               - Conference Call -
                    Second Quarter 2001 Earnings Announcement

                                  July 19, 2001
                             Los Angeles, California

     Thank you, Steve.

     As Steve reported, we had another outstanding quarter thanks to continued
strong performance by our oil and gas operations and encouraging signs of
recovery in our chemical business. Our earnings for the first half of the year
are the highest of any six-month period in the company's history. The
acceleration of our debt reduction program by selling two non-core assets at
very attractive prices has produced our strongest balance sheet in more than two
decades. Our balance sheet will grow even stronger as we continue to pay down
debt in the second half of the year.

                                       8


     Since 1997, we've concentrated on growing our oil and gas business by
narrowing our geographic scope to three core areas, divesting non-core and
under-performing assets and focusing on large, long-lived "legacy" assets. We've
targeted the Middle East as the premier growth area among our core areas that
also include the U.S. and Latin America. We believe we have the strongest
position in the Middle East of any company our size.

     Occidental has been an important player in the region ever since we
discovered the billion-barrel Augila field in Libya in 1966. In the meantime,
we've established strong positions in Oman, Qatar and Yemen. We're the largest
private oil producer in Oman where we've enjoyed considerable exploration
success. We're the operator of the largest, most successful enhanced oil
recovery project in Qatar. And, we're currently the largest holder of
exploration acreage in Yemen where we hope to add to our existing oil production
base in Masila and East Shabwa.

     By now I'm sure you're all aware that Occidental was one of eight western
oil companies, including five U.S. firms, to win a stake in the Saudi Arabia
Natural Gas Initiative. This Initiative marks the first time the Kingdom has
opened its doors to foreign investment in the energy sector since the 1970s. On
June 3, I joined the CEOs of the other companies in Jeddah, Saudi Arabia to sign
preliminary agreements covering the three huge projects that make up this
Initiative. The Saudi leadership has made it clear that they expect the
partnership to be a rewarding experience for all participants that will open the
door to other investment opportunities.

     Occidental is a member of the Core Venture 2 consortium, which will be
investing in the Red Sea area. Occidental and Marathon each will have a
20-percent interest in this multi- billion dollar project, while ExxonMobil is
the lead partner with a 60-percent interest. The Red Sea venture involves
development of discovered gas from the Midyan and Barqan fields located in the
northwest part of the Kingdom, and construction of related gas processing and
pipeline facilities. The consortium expects to build at least one power plant
and a water desalination unit, as well as evaluate the potential for a
petrochemical plant. The project also calls for onshore and offshore exploration
in Blocks 40 to 49 located along the Red Sea. Exploration success in these
blocks will lay the foundation for additional investment opportunities in power
generation, water desalination and petrochemicals in the western part of the
Kingdom. The Kingdom has emphasized that the companies were selected as
long-term, strategic partners and each company in Core Venture 2 will
participate in all segments of the venture.

     The project's potential is enormous given the geology of the region and the
rapidly growing local market. Saudi Arabia is the world's biggest hydrocarbon
province with the world's largest oil reserves and fourth largest natural gas
reserves. The Kingdom currently consumes about 4 billion cubic feet of natural
gas per day and expects that number to rise to 7 billion cubic feet per day in
2003. Current estimates indicate the Kingdom will need from 12 to 14 billion
cubic feet per day to meet its consumption projections by 2025.

     Saudi Aramco opened data rooms earlier this month to allow the consortium's
technical experts to gather additional data for use in their evaluation of the
project. A new negotiating team has been formed that is comprised of members of
the Ministries and Government agencies directly involved in the Initiative, as
well as a number of specialized sub-committees to deal with various aspects of
the project. A ministerial committee headed by Foreign Minister Prince Saud

                                       9


al-Faisal will continue to oversee the entire process until definitive
agreements are reached at the end of this year or early next year.

     Saudi leaders see these projects as the beginning of the next phase of the
Kingdom's industrial development. This phase will focus on further development
of the Kingdom's natural gas reserves to diversify and expand industrial
development and to create thousands of new jobs for Saudi citizens.

     For Occidental, participation in the Red Sea project means an attractive
return on investment and an even stronger presence in one of our core areas.
Recent news reports have noted that the expected integrated rate of return for
the Kingdom's core venture projects, each of which includes upstream, midstream,
and downstream components, will make them very competitive with rates of return
for other energy projects around the world. The Saudi leaders recognize this
important consideration and want their partners to be successful so that the
companies will be encouraged to continue to invest in the Kingdom for many years
to come.

     Given the reasonable level of risk involved, and the expectation of quite
attractive rates of return, Occidental is very excited about the opportunity to
participate in the Kingdom's historic Natural Gas Initiative.

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

United States: California crude oil and liquids production is down due to the
swap of Milne Point production for the Bravo Dome CO2 assets. 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 decrease in Colombia's oil production is a result of pipeline
disruption. 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.

Eastern Hemisphere: The decline in Qatar production is due primarily to a timing
issue. In the second quarter of this year there was one less cargo shipment than
normal while the second quarter of last year had an extra cargo shipment.

CHLORINE
--------
OXYCHEM COMMENTARY
------------------

o    Demand for chlorine is expected to remain weak in the 2nd half of 2001.
     Chlorine to EDC is expected to remain significantly below 2000 levels, as
     demand is not expected to rebound until 2002.

o    Prices are not expected to improve from the 2nd quarter levels for the
     remainder of 2001.

INFLUENCING FACTORS:
--------------------
Demand into the vinyls sector has been adversely affected and overall demand
into other key market segments has been lackluster due to reduced
housing/construction demand and the general economic slowdown. With limited new
production capacity, returning demand will drive long-term volume and upward
price pressures.

CAUSTIC
-------
OXYCHEM COMMENTARY
------------------

o    Pricing is expected to be under pressure in the 2nd half due to continued
     weak demand and higher imports.

o    Demand continues to remain balanced.

o    U.S. Gulf Coast spot prices are expected to fall $50-70 per ton from peak
     1st half levels due to the continued economic slowdown.

INFLUENCING FACTORS:
--------------------
Demand has been weakened as a result of global economic slowdown, but more
importantly, as a result of additional caustic volume from Qatar and lower
exports to Asia and Australia. Lower operating rates will continue to limit
supply, but weak caustic demand has begun exerting downward pressure on prices.

EDC
---
OXYCHEM COMMENTARY
------------------

o    Demand in general is expected to remain weak. Additional supply due to
     lower feedstock cost still exists in other parts of the world. 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.

o    Based on forecasted weak demand, low prices and high feedstock costs,
     OxyChem idled its 750,000 ton per year EDC facility at Ingleside, Texas on
     June 1st. It will remain idle until improved economics justify resumption
     of operations.

INFLUENCING FACTORS:
--------------------
Lower demand into the export vinyls market and declining volumes for VCM/PVC
continue to soften pricing from all-time highs in 2000.

PVC/VCM
-------
OXYCHEM COMMENTARY
------------------
o    Domestic PVC demand improved through the 2nd quarter as converters
     increased operating rates in order to maintain a balanced supply chain.

                                       22

o    Domestic PVC prices fell slightly through the 2nd quarter, down from a high
     in March 2001, as feedstock costs weakened.

o    Export PVC prices into Asia continued to decline from previous levels for
     June delivery. Export volumes from the U.S. are being impacted as margins
     have been squeezed below break-even points.

o    Domestic demand for VCM is weak but steady. Despite significant planned and
     unplanned VCM outages at Dow, OxyVinyls, Formosa and Georgia Gulf, VCM
     supply continues to outpace current demand.

o    VCM export prices peaked at the beginning of the 2nd quarter due to Asian
     outages. Recent prices have dropped rapidly as demand in Asia did not
     return to expected levels.

INFLUENCING FACTORS:
--------------------
Prices will remain under pressure due to the combined effects of industry excess
capacity and anticipated feedstock price erosion.
