Permian Basin Carries Half of U.S. Crude Output as Older Texas Fields Recede
America averaged a production record of 13.6 million barrels per day in 2025, but nearly half flows from one basin as older Texas plays decline.
U.S. crude oil and lease-condensate production averaged a record 13.6 million barrels per day in 2025, reaching a monthly peak of 13.93 million barrels per day in April, Forbes reported on Wednesday (2026-07-16). The Permian Basin in West Texas and southeastern New Mexico produced 6.6 million barrels per day — roughly 47% of the national total. No other U.S. play approaches that share.4
The concentration is a product of fracking. Between 2005 and 2015, U.S. petroleum production rose from 8 million to 15 million barrels per day, the Economist has reported, with capital moving into tight-rock formations offering high per-well productivity. Older Texas conventional plays, which once formed a distributed supply base, lost relative ground with each drilling cycle as the Permian absorbed the bulk of investment. The result is a national production record carried overwhelmingly by one geological basin.3,4
The concentration creates supply vulnerabilities that the headline output figure does not capture. When one basin accounts for nearly half of national crude, a sustained disruption to West Texas and southeastern New Mexico infrastructure carries systemic consequences for U.S. output, with no comparable domestic play positioned to offset the loss. Older Texas formations are not operating at a scale that would allow them to serve as meaningful compensation.4
Natural gas production has followed the same geographic logic. Comstock Resources operates primarily in the Haynesville Shale in East Texas and Louisiana, with 100% natural gas production positioned to serve Gulf Coast LNG export demand, Nasdaq reported (2026-05-21). One Appalachian Basin-focused producer described in the same analysis drew more than 90% of its production and sales from formations in Ohio, Pennsylvania, and West Virginia. Legacy conventional gas plays in Texas do not feature in either growth story.1
NYMEX Henry Hub front-month traded at $2.90 per MMBtu on Thursday (2026-07-17). The Zacks consensus estimate implies Comstock Resources' 2026 earnings per share will run approximately 37% above 2025 levels, partly on the expectation that LNG export growth will eventually pull the front month higher. At $2.90, that assumption remains untested.1
Russia produced approximately 9.9 million barrels per day in 2025, with U.S. output running approximately 40% higher, Forbes reported. The production gap has persisted through Western sanctions, voluntary OPEC+ curbs, and the third year of the Ukraine conflict. China purchased approximately half of Russia's crude exports in June, becoming the effective outlet for barrels that Western refiners will not process.4
China's strategic reserve build adds a separate demand variable. OilPrice.com analysis estimates the country has accumulated 1.2 to 1.3 billion barrels of crude, potentially the largest national stockpile, with January-February imports running approximately 16% above year-earlier levels at close to 12 million barrels per day. Western analysts have periodically forecast a slowdown in Chinese crude demand; the import data has not reflected it. China's reserve scale gives Beijing the capacity to curtail new purchases for months without constraining domestic refinery runs, putting an informal ceiling on how far ICE Brent crude front-month can move before Chinese buying retreats. ICE Brent crude front-month traded at $84.90 per barrel on Thursday (2026-07-17).2
Should Permian production growth stall, there is no other domestic formation positioned to compensate. Older Texas plays have declined too far, and the Appalachian is a gas basin. With NYMEX Henry Hub front-month at $2.90 per MMBtu, the economics for reviving legacy Texas gas production are absent. China's estimated 1.3 billion barrel reserve remains the most consequential demand variable facing ICE Brent pricing through the second half of 2026.4,1,2
