Upstream
Unconventional
Leadership in developing unconventional resources
We operate throughout the United States, from the Permian Basin to the Bakken to Appalachia, holding approximately 10 million gross acres.*
*Unconventional acreage in the continental U.S., excluding EOR and conventional assets.
Permian
Nearly half of all U.S. oil and gas production comes from the Permian Basin, and we are the largest contiguous acreage holder in the Permian. In 2026, we achieved record production of more than 1.8 million oil-equivalent barrels per day. By 2030, we expect to double our production in the Permian Basin vs. 2024, to approximately 2.5 million oil-equivalent barrels per day.
Scaling an innovative development approach
Cube development enables us to drill multiple horizontal wells in stacked intervals from a single surface location. By applying this approach across our acreage, we can safely bring production online faster while maximizing recovery, reducing costs and minimizing our environmental footprint. This approach enables a development plan and return profile that is resilient across a wide range of prices and market scenarios.
Investing in integration
We have invested in infrastructure from New Mexico to the U.S. Gulf Coast to provide logistics flexibility and maximize the integrated value of our growing Permian production. Our midstream assets connect our advantaged Permian volumes to our U.S. Gulf Coast refining and chemical manufacturing assets, connecting the largest resource base in the U.S. to the largest manufacturing footprint on the Gulf Coast.
