does not undertake any obligation to update any forward-looking statements as a result of new information, future events
or otherwise. The United States Securities and Exchange Commission (SEC) permits oil and natural gas companies, in their
filings with the SEC, to disclose only proved reserves demonstrated by actual production or conclusive formation tests to be
economically producible under existing economic and operating conditions. We use certain terms in this report, such as gross
oil reserves, estimated proved reserves, probable, possible and recoverable reserves and oil in place, that the SEC’s guidelines
strictly prohibit us from using in filings with the SEC. Additionally, the SEC requires oil and natural gas companies, in their
filings, to disclose non-financial statistical information about their consolidated entities separately from such information
about their equity holdings and not to show combined totals. Certain information in this report is shown on a combined
basis; however, the information is disclosed separately in the “Notes to the Consolidated Financial Statements” included in

Occidental Petroleum Corporation (nyse:oxy)
is a leading international oil and gas exploration
and production company, as well as a major
North American chemical manufacturer.
The fourth-largest U.S. oil and gas company, based on market capitalization of more
than $60 billion, Oxy engages in oil and gas exploration and production in three core
regions: the United States, the Middle East/North Africa and Latin America. OxyChem,
a wholly owned subsidiary, manufactures and markets chlor-alkali products and
vinyls, and is the nation’s largest merchant marketer of chlorine and caustic soda.
Oxy’s U.S. operations in the Permian Basin of southwest Texas and southeast New
Mexico, Mid-Continent and California account for more than 60 percent of the
company’s total worldwide oil and gas production. Oxy is the largest oil producer in
Texas, the second-largest in New Mexico and the third-largest in California, where it
also is the largest producer of natural gas.
In the increasingly important Middle East/North Africa region, Oxy currently has
operations in Libya, Oman, Qatar, United Arab Emirates and Yemen, which collec-
tively account for approximately one-quarter of the company’s total worldwide
production. Oxy is also a partner in the transborder Dolphin Project that supplies
natural gas from Qatar to markets in the United Arab Emirates and Oman. Oxy’s Latin
America operations in Argentina, Bolivia and Colombia account for approximately
13 percent of total production.
Oxy is an industry leader in applying advanced technology to boost production from
mature oil and gas fields and access hard-to-reach reserves. With more than 9,000
employees, Oxy is committed to respecting the environment, protecting safety and
upholding high standards of social responsibility throughout its worldwide operations.

Strategy for steady growth
Oxy’s consistently strong financial performance over the past
15 years reflects our disciplined business strategy
The robust performance by the oil and gas segment
in recent years is another reflection of Oxy’s effective
business strategy.
We focus on large, long-lived “legacy” oil and gas assets where Oxy can enhance
production, and we invest only in projects we believe will generate above-cost-of-
capital returns throughout the business cycle. We continued to strengthen our asset
base in 2007 within each of our core geographic regions: the United States, the
Middle East/North Africa and Latin America.
Earnings from our oil and gas segment in 2007 set a new company record for the
fourth consecutive year. Oil and gas earnings from worldwide operations totaled
$8.3 billion, an increase of more than 20 percent from the previous record of $6.9
billion earned by this segment in 2006.
Higher oil prices, along with

oil and natural gas production averaged 570,000 barrels of oil equivalent (BOE) per
day, an increase of 4.6 percent over the 545,000 BOE per day produced in 2006.
Oxy is a worldwide industry leader in applying advanced technology to boost
production from mature oil and gas fields and access hard-to-reach reserves.
Furthermore, we consistently replace and expand our reserves through improved
recovery, strategic acquisitions and focused exploration.
Consolidated proved reserve additions from all sources totaled 242 million BOE in
2007, compared to production of 209 million BOE, for a production replacement
rate of 116 percent. For the three-year period 2005 through 2007, Oxy’s consolidated
proved reserve additions totaled 1.125 billion BOE and total production equaled 580
million BOE, for a reserve replacement rate of 194 percent. More than 90 percent
of the net additions in 2007 were in the United States, primarily in the Permian Basin
in Texas and New Mexico, the Elk Hills field in California and the Rocky Mountains.

Corporate
social responsibility
The health and safety of our employees, contractors,
neighbors and customers, as well as sound and sensitive
environmental practices, are key priorities for Oxy.
Oxy’s health, environment and safety (HES) management systems continually evolve to
meet the changing needs of our growing business. We work diligently to implement
progressive health, environmental, safety, process risk and security standards at
all new and ongoing operations. Incidents are thoroughly investigated and their causes
promptly identified and corrected. Oxy continues to maintain a strong HES
risk management program, the results of which are regularly reviewed by senior
management and the Board of Directors.
We take pride in Oxy’s superior employee Injury and Illness Incidence Rate (IIR),
which measures recordable injuries and illnesses per 100 full-time workers per year.
Oxy’s IIR is one-fourth that of the oil and gas extractive industry overall, which puts
us ahead even of such professions as legal services and dentists for employee safety,
according to the most recent figures from the U.S. Bureau of Labor Statistics. Our 2007
IIR was 0.5, virtually the same as the previous year. And it is merely one indicator of
the company’s excellent safety record.
We constantly work to save costs while enhancing energy efficiency in our operations,
thereby reducing greenhouse gas (GHG) emissions. Oxy voluntarily reports on GHG
emissions and actively participates in trade association efforts to discuss a wide
spectrum of environmental issues. In addition, we are utilizing several highly efficient

of Oxy’s future growth
$3.6 billion capital spending
Expected total oil and gas capital spending for 2008
Oxy’s performance in 2007 again ranked among the
strongest in the oil and gas industry.
While these results are gratifying, we are focused on the future in order to build on
this success in 2008 and beyond.
Adhering to our program of disciplined financial management, we will continue
to pursue top-quartile results and enhanced value for Oxy stockholders. With the
excellent recent additions to Oxy’s asset portfolio, ongoing solid production perfor-
mance and promising projects in the pipeline, along with continued strong energy
prices, we fully expect 2008 to be another standout year for the company.
We expect oil and gas production for the full year of 2008 to increase to approximately
620,000 to 630,000 BOE per day, based on $80 per barrel average West Texas
Intermediate (WTI) prices, as compared to our 2007 rate of 570,000 BOE per day.
We anticipate this increase will include the Dolphin Project’s full-year operations
and increased production from the Mukhaizna oil field in Oman, as well as our
Argentina and Colombia assets. We expect our total oil and gas capital spending
for 2008 to be approximately $3.6 billion, including increased capital spending in
our Argentina, Colombia, Libya and California operations.
We believe new opportunities in the Middle East and North Africa, where we are
actively pursuing and negotiating several projects, will be an important source of
Oxy’s future growth.
We also will continue to grow through additional attractive acquisitions in each of
our core regions. However, as always, we will only enter into agreements that we
expect to meet our stringent standards for financial return.
Oxy takes pride in applying expertise and experience to help meet the world’s energy
needs and fuel economic growth. Our success is built on technical know-how,
business acumen, strong partnerships and proven ability to deliver superior results.
