Abstract

Gravity-Assisted Inert Gas Injection performance was investigated in heterogeneous packed model through a number of experiments for recovering waterflood residual oil. These heterogeneous media consisted of isolated regions of large pore-sizes, at the macroscopic scale, randomly distributed in small-size continuum. In such heterogeneous media the waterflood residual oil saturation is proportional to the volume fraction of heterogeneity. Experimental results of tertiary gravity drainage experiments have shown that the presence of large pore-size regions leads to the gas invading through such regions and thus improve the recovery of the large amount of residual oil.
