EOG — EOG Resources, Inc.

Chevron is one of the largest integrated oil and gas companies in the world, with upstream exploration and production operations in the Permian Basin, Gulf of Mexico, Australia (LNG), Kazakhstan, and other regions. Its downstream refining operations produce gasoline, jet fuel, and petrochemicals, while chemicals and lubricants generate additional revenue. Chevron is one of the most financially disciplined major oil companies, known for variable dividend commitments and share buybacks tied to cash flow. Chevron attempted to acquire Hess Corporation in 2023, which faced arbitration complications related to Guyana.

ConocoPhillips is the world's largest independent oil and gas exploration and production company, having divested its downstream refining assets in 2012. The company focuses exclusively on upstream production across the Permian Basin, Eagle Ford, Bakken, Alaska, Canada, Norway, Australia, and other international basins. ConocoPhillips is known for disciplined capital allocation, a low cost of supply (breakeven price), and a shareholder-return framework that prioritizes variable returns of capital (VROC) above base dividends.

Pioneer Natural Resources was one of the largest Permian Basin pure-play oil and gas producers, with premier acreage in the Midland Basin and Delaware Basin in West Texas. Founded by legendary oilman Scott Sheffield, Pioneer became the defining Permian Basin compounder over the 2010s through disciplined horizontal well development, variable return dividends, and operational excellence. ExxonMobil acquired Pioneer in a $59.5 billion all-stock deal that closed in May 2024 in what was the largest oil industry acquisition in decades. Pioneer shares are no longer publicly traded following the acquisition.
