Experimental and simulation studies of sequestration of supercritical carbon dioxide in depleted gas reservoirs

This paper presents experimental and simulation studies to evaluate the feasibility of sequestering supercritical CO 2 in depleted gas reservoirs. Experimental results were simulated to obtain gas-liquid relative permeability curves used in the field simulation study. A 3D simulation model of one-eighth of a five-spot pattern was constructed to evaluate injection of supercritical CO 2 under typical field conditions.
