| Summary |
"A numerical model for linear, three-phase fluid flow in a stratified petroleum reservoir has been developed for the purpose of studying water-flooding performance characteristics. Gravity forces, capillary pressure and cross-flow were neglected, but the fluids were considered compressible and evaluations of dissolved gas concentrations have been accounted for. The model was used in evaluating the performance of a water flood project for a hypothetical reservoir which contained the three phases of oil, gas, and water. The results were then compared with those obtained using the Dykstra-Parsons technique. The model produces results which were found to be similar to those obtained by the Dykstra-Parsons method for the displacement of oil by water with no gas present, but poor agreement resulted when free gas saturations were formed. The results obtained using the numerical model are considered to be more realistic than those obtained by the Dykstra-Parsons method in depleted oil sands with a substantial gas saturation since the Dykstra-Parsons model was built on the assumption that only one phase flows at a point and water displace oil in a piston-like manner. When a free gas saturation is formed at the production well, the oil mobility is reduced substantially resulting in a lower oil recovery at water breakthrough than can be predicted by the Dykstra-Parsons technique"--Abstract, leaf ii. |
