ABSTRACT:
A foamed gel composition useful in a subterranean hydrocarbon-bearing formation to reduce the permeability of a treatment region therein or control the mobility of a drive fluid in the formation. The foamed gel is formed from a crosslinkable carboxylate-containing polymer, a crosslinking agent containing a reactive transition metal cation, a polyvinyl alcohol, an aqueous solvent, and an added gas.
