abstract
Studies were conducted on the permeability-reducing characteristics of polyacrylamide/chromium gels in high-permeability sandpacks containing residual oil saturation. Results of the polyacrylamide/chromium gel study have shown that weak gels reduce sandpack permeabilities a small amount; strong gels completely plug sandpacks when the pressure differential is below the yield stress of the gel. The gel yield stress measured in simple tube-flow experiments correlated well with the plugging observed in the sandpack experiments.
