U. S. Energy Research and Development Administration field experiment (for tar sand oil recovery)
E.R.D.A.'s Laramie Energy Research Center is equipping a small-scale field experiment to test the reverse combustion process to recover oil from tar sand. This field experiment, the first of a planned series, will extend the results of laboratory work and will identify the problems that will affect the application of the process in the field. The reverse combustion process will be tested in preference to the alternative forward process, because laboratory experiments have indicated that reduction of permeability downstream from the combustion zone by condensing vapors is not likely to occur. A tar sand section 10 ft thick at the top of the Rim Rock Sandstone has been selected for the experiment. The section has a porosity of about 28.5%, an oil saturation of about 52%, a water saturation of 15.5%, a permeability of 182 mdarcy with the bitumen in place, and a permeability of 615 mdarcy after the oil is extracted. The oil has a gravity of about 10/sup 0/API and a viscosity of over 500,000 cp at reservoir temperature.
