Influence of polymer structure on the gelation kinetics and gel strength of acrylamide‐based copolymers, bentonite and polyethylenimine systems for conformance control of oil reservoirs

ABSTRACT In oil reservoirs with conformance problems, the sweep and oil recovery efficiencies tend to be low because the injected oil‐recovery drive fluids channel through high‐permeability zones and/or anomalies, leaving behind part of the displaceable oil in unswept low‐permeability zones. In thes...
