Occidental Petroleum Corp /DE/ (NYSE: OXY), headquartered in Houston, Texas, United States, is a long-established U.S. energy company with more than a century of operating history. Founded in the early 20th century, Occidental has evolved from a diversified resource group into a more focused upstream energy platform. For investors, the company is best understood as a large-scale oil and gas producer with complementary midstream, low-carbon, and portfolio-management capabilities rather than as a fully integrated supermajor. Today, Occidental’s core business is the exploration, development, and production of oil and natural gas. Its operations are supported by midstream and marketing activities that help provide flow assurance, optimize logistics, and enhance the value of produced hydrocarbons. The company has also built a strategic low-carbon portfolio, including direct air capture, carbon capture and sequestration, and related decarbonization solutions through its Oxy Low Carbon Ventures and 1PointFive platforms. That makes Occidental one of the more visible U.S. producers trying to combine traditional hydrocarbon cash generation with longer-term emissions-reduction technologies. Occidental has historically operated across multiple segments, including chemicals through OxyChem. However, in early 2026 the company completed the sale of OxyChem to Berkshire Hathaway, marking an important strategic shift toward a more concentrated oil and gas model. This transaction is significant because it strengthens Occidental’s balance sheet, simplifies the group structure, and increases management’s focus on its upstream asset base. The move also illustrates the company’s ongoing effort to prioritize debt reduction, capital discipline, and shareholder returns. From a competitive standpoint, Occidental holds a strong position in the U.S. onshore market, especially in the Permian Basin, which remains one of the most attractive and cost-efficient oil provinces globally. The company also has material exposure to the Gulf of Mexico and selected international operations, including Oman, giving it geographic diversification beyond the United States. This portfolio mix provides scale and optionality, but Occidental remains highly sensitive to crude oil and natural gas prices, operating costs, reserve replacement, and regulatory developments. Recent corporate developments have been particularly active. Occidental completed the acquisition of CrownRock, expanding its Permian footprint. It also announced a Gulf of America oil discovery at Bandit in April 2026 and extended operations in Oman through a 15-year agreement. Quarterly results published in 2025 and early 2026 showed continued emphasis on oil and gas earnings, free cash flow, deleveraging, and capital returns. Overall, Occidental is a NYSE-listed U.S. energy company in the midst of strategic simplification, with a strong upstream base, selective international exposure, and an increasingly clear focus on shareholder value creation.
