Millions of years before dinosaurs went extinct, what is now Utah was submerged by a broad, shallow sea. Over millennia, as the water receded and tectonic plates shifted, rich organic marine material accumulated, forming thick layers of sediment that eventually became the fossil fuel deposits of the Uinta Basin in the northeastern part of the state. The formation is estimated to hold as many as 300 billion barrels of oil — more than the proven oil reserves of Saudi Arabia.
The basin's immense oil-producing potential remains largely untapped. Drillers in the Uinta Basin extract about 65,000 barrels of oil per day, or just over 1 percent of the more than 5 million barrels daily drilled in the Permian Basin, which straddles West Texas and New Mexico and is the country's most productive fossil fuel reserve. One of the biggest hurdles is the waxy and viscous quality of Uinta oil, which is so thick that it needs to be constantly heated to keep it liquid. The deposits are also trapped in tiny pores between rocks and more widely dispersed than other shale formations in the country. As a result, oil drillers have been tepid in exploring the basin, despite high gas prices and calls to boost American oil production.
