Occidental Petroleum Corp /De/ is a leading integrated energy company engaged in the exploration, production, and marketing of oil, natural gas, and related products. The company also manufactures a broad portfolio of chemical products through its OxyChem subsidiary. It provides midstream services that include gathering, processing, transportation, storage, and marketing of hydrocarbons and carbon dioxide. Occidental's operations are concentrated in the United States with additional activities in the Middle East and Africa.

Revenue is generated primarily from the sale of crude oil, natural gas liquids, and natural gas produced from its upstream assets. The company also earns income from the sale of chemical products such as ethylene, polyvinyl chloride, and performance chemicals used in various industrial applications. Midstream contributions come from fees for gathering, processing, transporting, storing, and marketing oil, natural gas, natural gas liquids, and carbon dioxide. Additionally, Occidental derives revenue from marketing and trading activities that optimize the value of its hydrocarbon portfolio.

The company operates through the following segments:

• Oil and Gas: This segment explores for and produces crude oil, natural gas liquids, and natural gas. Core producing regions include the Permian Basin in Texas and New Mexico, the DJ Basin in Colorado, and offshore facilities in the Gulf of Mexico. International operations are located in the Middle East and North Africa where Occidental holds interests in onshore fields and development projects. The segment also invests in enhanced oil recovery techniques and carbon capture initiatives to extend reserve life and reduce emissions.

• Chemical: This segment manufactures basic chemicals, vinyls, and performance products through its OxyChem subsidiary. Key products include ethylene, propylene, polyethylene, polyvinyl chloride, and chlorinated solvents. These chemicals serve markets such as construction, packaging, automotive, agriculture, and water treatment. OxyChem operates manufacturing plants along the Gulf Coast and in other domestic locations, leveraging integrated logistics to supply customers efficiently.

• Midstream and Marketing: This segment gathers, processes, transports, stores, and markets oil, natural gas, natural gas liquids, and carbon dioxide. It operates an extensive network of pipelines, processing plants, and storage facilities primarily in the Permian Basin and Rocky Mountain regions. The marketing arm optimizes the sale of hydrocarbons through contracts with refineries, petrochemical companies, and power generators. Additionally, the segment manages carbon dioxide streams for enhanced oil recovery and sequestration projects.

Occidental Petroleum Corp /De/ ranks among the largest independent exploration and production companies in the United States, competing with integrated majors such as ExxonMobil, Chevron, and BP as well as independent peers like ConocoPhillips and EOG Resources. Its competitive advantages stem from a substantial acreage position in the high growth Permian Basin, which provides access to low cost, high margin oil and gas resources. The company benefits from an integrated business model that links upstream production, chemical manufacturing, and midstream logistics, enabling efficient value capture across the hydrocarbon chain. Ongoing investments in carbon capture utilization and storage, as well as low carbon initiatives, further differentiate Occidental in an evolving energy landscape. The company leverages scale, operational discipline, and technical expertise to generate resilient cash flows through commodity price cycles.

The company serves a diverse customer base that includes refineries that process crude oil into fuels and petrochemical feedstocks, petrochemical plants that convert ethylene and propylene into plastics and synthetic fibers, industrial manufacturers that rely on chemicals for production processes, utilities that use natural gas for power generation, and energy traders who buy and sell hydrocarbons in wholesale markets. Occidental also supplies carbon dioxide to enhanced oil recovery operators and sequestration partners.
