The United States is swimming in oil and gas. But processing the new-found bounty is posing a challenge to U.S. refiners, which can't come to grips with the abundance in domestic supply.
A production renaissance has catapulted the United States into the upper strata of global energy producers. Yet with fewer than 150 refineries, the U.S. has a surprisingly limited capacity to process the bounty.
"Some refineries are better suited for light sweet crude," while others—primarily on the Gulf Coast—are better optimized for the heavier, international variety of oil, said Bob Greco, director of upstream operations for the American Petroleum Institute.
The huge increase in shale production in places like North Dakota is helping to revitalize East Coast refineries, Greco said in an interview.
