摘要：
A method and a system for consolidating a subterranean formation are provided. An exemplary method includes injecting a water-in-oil emulsion into an unconsolidated subterranean formation, wherein the water-in-oil emulsion includes comonomers in an oil phase to form a polyurethane resin, and a catalyst in an aqueous phase. The method also includes allowing the polyurethane resin to cure to form a porous polymeric network.
