Development, testing and application of a numerical simulator for predicting miscible flood performance
Variants of a 3-phase, 3-dimensional, compressible, numerical reservoir simulator have been developed which are capable of modeling the essential features of miscible displacement, while leaving the fine structure of unstable miscible flow unresolved. In the 3-component version, wetting (water) and nonwetting (hydrocarbon) phases are considered with 2-component miscible flow in the hydrocarbon phase. A mixing parameter model is used to represent viscous behavior of the oil and solvent as modified by dispersion at the flood front. Using the 4-component version, slug as well as continuous solvent injection may be examined. The efficiency of the 3-component simulator is demonstrated by comparison of predicted performance with experimental results from both linear and areal displacements in laboratory models. Predictions also are compared with reported results of miscible displacements conducted in a shallow, water-bearing sand. The application of the simulator is demonstrated by its use in the evaluation of alternate flooding configurations and operational policies for a field example. (21 refs.)
