Recovery of oil from Utah's tar sands. Final report 1975-77

Utah has at least 25 billion barrels of potential oil or bitumen existing as tar sands. In this program, methods for extracting the bitumen from the sands, analyzing and characterizing the products, and upgrading the bitumen were studied. In particular, the extraction of bitumen from Utah tar sands by a hot-water digestion and flotation technique and by a thermal, fluidized-bed technique are shown to be feasible.
