Experimental study on the oil and water behavior in porous media under stepwise-approximately isothermal conditions with multi-phase fluid flow
In view of limited experimental information and incomplete knowledge about the various regions existing in the in situ combustion process, a model was designed to simulate the process in the regions from water bank to the evaporation and visbreaking region. A linear Berea sandpack 2-7/32 in. diam and 13 in. long was initially saturated with oil, water, and air. Experiments using various combinations of gas and water injection rates, temperature residence time, and system pressure were conducted under programed stepwise approximately isothermal conditions. The objectives were to investigate the mechanism of liquid movement, the profile of liquid saturations, and the concentration of the remaining oil which ultimately provides the fuel for combustion. The results obtained from all crude oil runs show that the residual oil saturation at 400/sup 0/F ranges from 11.5 to 13.9%. The fuel concentration estimated from this residual oil using the fluid coking factor ranges from less than 0.09 to 0.46 lb of fuel per 100 lb of sand. If the ultimate coking factor is used, the fuel concentration ranges from less than 0.66 to 1.35 lb of fuel per 10 lb of sand.
