ABSTRACT:
Polymerization in-situ to effect permeability contrast correction in oil-bearing subterranean formations comprising the injection of at least one water-soluble monomer comprising N-3-oxohydrocarbon-substituted acrylamides, such as diacetone acrylamide, and optionally at least one water-soluble comonomer, such as alpha,beta-unsaturated amides, alpha,beta-unsaturated nitriles, vinyl-containing sulfonates and N-vinyl amides and polymerization initiator to cause polymerization and formation of water-insoluble polymers in high permeability zones.
