The Permian Basin of Texas and New Mexico holds 60 billion to 70 billion barrels of yet-to-be pumped crude oil, according to a study by IHS Markit Ltd. The Permian region’s so-called recoverable resources would be enough to supply every refinery in the U.S. for 12 years and have a market value of about $3.3 trillion at current prices for West Texas Intermediate oil, the domestic benchmark.

The estimate may grow as IHS geologists and data scientists extend their analytical techniques to deeper geological zones. “The Permian Basin is America’s super basin in terms of its oil and gas production history and for operators […]
