COMPARISON OF ALTERNATING-DIRECTION (ADI) AND SUCCESSIVE OVER- RELAXATION (SOR) TECHNIQUES IN SIMULATION OF RESERVOIR FLUID FLOW

Abstract

Study presents calculations simulating two-phase (water and gas injection) flow and accounting for effects of capillary pressure, relative permeability, gravity and reservoir heterogeneity; results show that for oil-water simulation problems investigated, ADI iterative technique is superior to all variations of SOR technique employing single relaxation factors.
