Patent
·
OSTI ID:6891745
A method for reducing subterranean formation permeability to brines wherein the formation is penetrated by at least one well bore comprising, injecting into the formation 2 slugs of an aqueous polymer solution interspaced with a brine slug. A method for reducing the quantity of water recovered from a subterranean formation which is penetrated by at least one well bore wherein in one embodiment prolonged mobility control and/or plugging is maintained with the injection into the formation of slugs of aqueous solutions of at least 2 distinguishable viscosity increasing agents separated by a brine spacer slug.
