Occidental Petroleum Corporation is one of the largest U.S. oil and gas companies based on equity market capitalization. Occidental’s success is a direct outcome of the company’s leadership and ongoing commitment to enhance stockholder value.

Employing a disciplined financial strategy and focusing on high-potential oil and gas assets in our core geographic regions, Occidental has consistently achieved top-tier results, including:

  • In 2013, Occidental achieved average worldwide oil and gas production of 763,000 barrels of oil equivalent (BOE) per day.
  • At year-end 2013, Occidental had total proved reserves of 3.5 billion BOE – a new company record. Occidental replaced 169 percent of its oil and gas production in 2013*.
  • Return on capital employed (ROCE)** was 12.2 percent in 2013.
  • Occidental returned $1.6 billion to shareholders in 2013 in the form of dividends. 
  • Occidental's market capitalization at year-end 2013 was $75.7 billion.
  • Occidental has paid quarterly dividends to its stockholders continuously since 1975. Effective February 2014, the annual dividend was increased 12.5 percent to an annual rate of $2.88 per share.

Occidental is the largest onshore producer of oil and liquids combined in the 48 contiguous United States. It is the largest operator and largest producer of oil in the Permian Basin of West Texas and southeast New Mexico, and California’s largest natural gas producer and largest oil and gas producer on a gross-operated barrels of oil equivalent basis. Oxy was founded in California in 1920 and made its first major discovery in the Sacramento Valley in 1961. Through 2013, more than 60 percent of the company’s worldwide production comes from its U.S. operations.

Occidental has been an active investor in the Middle East region for more than 40 years. The region currently accounts for more than a third of Occidental’s worldwide production. The majority of our regional capital is deployed in our focus areas of Qatar, Oman and the United Arab Emirates.

Occidental also has operations in Latin America, primarily in Colombia. More than 1.2 billion total barrels of oil have been produced at Colombia’s Caño Limón Field since it was discovered by Occidental in 1983.

Occidental Chemical Corporation (OxyChem) is a leading North American manufacturer of basic chemicals and vinyls used in products essential to public health and modern life. For every product it markets in the U.S., OxyChem’s market position is No. 1 or No. 2. OxyChem was established in 1987.

Management expects improved recovery, extensions and discovery to continue as the main sources for reserves additions, but factors such as geology, government regulations and permits and the effectiveness of development plans are partially or fully outside their control and could cause results to differ materially from expectations.
