The purpose of this study was to determine the approximate range of enhanced oil recovery which might be expected from CO/sub 2/ flooding, based on a five-spot symmetry element. A computer simulation study of the effects of crossflow between sublayers of a single major zone in a San Andres dolomite reservoir during injection of a CO/sub 2/ slug followed by a water-flood shows that the crossflow causes a substantial reduction in oil recovery. This loss can be reduced by use of alternate injection of small increments of CO/sub 2/ and water during the CO/sub 2/ slug injection. 27 refs.
