Devon Energy 

Devon Energy is an oil and gas producer with acreage in several top US shale plays. While roughly two-thirds of its production comes from the Permian Basin, it also holds a meaningful presence in the Anadarko and Bakken basins. After the merger with Coterra, it will have a foothold in the gas-driven Appalachian Basin as well. At the end of 2025, Devon reported net proved reserves of 2.4 billion barrels of oil equivalent, up from 2.2 billion in 2024. Net production averaged roughly 840,000 barrels of oil equivalent per day in 2025 at a ratio of 73% oil and natural gas liquids and 27% natural gas.
