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.
IHS spent three years studying output data from more than 440,000 wells to calculate the amount of crude remaining within the sprawling, mile-thick rock formation that pumps more oil than any other U.S. field, the London-based researcher said in a statement Monday.
"The results change the game for this basin and for geologists' interpretations," said John Roberts, executive director of global subsurface content operations at IHS Markit.
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 it presents a significant variety of stacked targets that are profitable at today's oil prices," Prithiraj Chungkham, director of unconventional resources for IHS, said in the statement.
The assessment may boost Pioneer Natural Resources Co. chairman Scott Sheffield's claim that the Permian is a 75 billion-barrel field that may rival Saudi Arabia's massive Ghawar field. In November, the U.S. Geological Survey estimated just one layer of the Permian known as the Wolfcamp holds 20 billion barrels of crude.
