Abstract: Disclosed is an α-glycol containing sulfonated epoxy resin composition and method for preparing said composition. The α-glycol containing sulfonated epoxy resin composition is made by forming a reaction product comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, followed by converting any unreacted epoxide groups in the reaction product to α-glycol groups by hydrolysis. Said α-glycol containing sulfonated epoxy resin compositions demonstrate good solubility in aqueous solutions and are useful for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.

Abstract: Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns α-glycol containing sulfonated epoxy resin composition and method for preparing said composition. The α-glycol containing sulfonated epoxy resin composition is made by forming a reaction product comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, followed by converting any unreacted epoxide groups in the reaction product to α-glycol groups by hydrolysis. Said α-glycol containing sulfonated epoxy resin compositions demonstrate good solubility in aqueous solutions and are useful for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.
