Think only Canadians need to worry about tar sands extraction? Think again.
In October, U.S. Oil Sands, Inc. joined Kentucky-based Arrakis Oil Recovery as the second company to receive a permit to produce U.S. tar sands. The Utah Water Quality Board gave U.S. Oil Sands a permit to extract 2,000 barrels of oil per day from Utah’s tar sands reserves.
Despite its name, U.S. Oil Sands is actually a Canadian outfit based in Calgary, Alberta. The company currently holds leases on just over 32,000 acres in Utah’s Uintah Basin. U.S. Oil Sands’ mining will take place at PR Spring on the Colorado Plateau in an area called the Bookcliffs, which straddles the Utah/Colorado border.
U.S. Oil Sands’ water-and-energy-intensive extraction process involves first digging up congealed tar sands, then crushing them to reduce their size. The company then mixes the crushed sand with large amounts of hot water (at a temperature of 122-176°F) to loosen up and liquefy the tarry, oil-containing residue and separating it from the sand.
