The Permian Basin remains a cornerstone of U.S. oil production, driven by technological advancements and operational efficiencies. Key players like EOG Resources (EOG), ExxonMobil (XOM), Diamondback Energy (FANG), and Chevron (CVX) are capitalizing on these gains to boost productivity and profitability.
EOG Resources has seen significant improvements in the Delaware Basin, with a 13% increase in daily drilling activity and a 5% rise in the length of horizontal wells completed per day during the first half of 2026. These enhancements have reduced drilling and completion costs to less than $710 per foot. The company's Janus gas processing plant operated at over 99% capacity, contributing to higher earnings. EOG expects a 5% increase in oil production and a 14% rise in total production for 2026.
ExxonMobil has expanded its Permian operations following the acquisition of Pioneer Natural Resources, achieving a record production of over 1.8 million barrels of oil equivalent per day in the second quarter of 2026. The company is leveraging advanced drilling technologies and longer horizontal wells to enhance efficiency and reduce costs. ExxonMobil aims to increase Permian production by 9% annually through 2030.
Diamondback Energy is focusing on cost reductions and well productivity, maintaining drilling costs at approximately $550 per foot in the Midland Basin. The company expects to generate $7.8 billion in free cash flow in 2026 and has doubled its share buyback authorization to $16 billion.
Chevron achieved a production milestone of 1 million barrels of oil equivalent per day in 2025 and reported record Permian production in the second quarter of 2026. The company anticipates a 25% decline in capital expenditure per barrel of oil equivalent in 2026 compared to 2025 and has achieved $3 billion in annualized structural cost reductions.
