6 APPENDIX C - In-situ production of Utah oil sands - Final Project Report - Reporting period: June 21, 2006 to October 21, 20092009-10Utah; Uinta Basin; Oil sand reservoirs; Whiterocks; Sunnyside; Oil; Oil extraction; In-situ; Heavy oil production; BitumenTwo oil sand reservoirs located in Utah's Uinta Basin were considered for analysis: Whiterocks, a small, steeply dipping, contained reservoir containing about 100 million barrels, and Sunnyside, a giant reservoir containing over four billion barrels of oil in place. Cyclic steam stimulation, steam a...
7 Bitumen recovery from tar sands1984-09-11Patent; Bitumen recovery; Tar sands; Kerosene; Flotation cell; BitumenA process for recovering bitumen from tar sands wherein the tar sands are pretreated with a diluent, such as kerosene in the preferred embodiment, to lower the viscosity of the bitumen such that it is in the range of about 5 to about 20 poise at the digestion temperature. The tar sands are then dige...
