    Abstract: A treatment fluid composition includes a carrier fluid and a curable hybrid resin. The curable hybrid resin includes a first curable resin (A) including a reactive silyl group that reacts with water downhole, a second curable resin (B), and a curing agent for the second curable resin (B). A method of treating a subterranean formation includes injecting a treatment fluid including a curable hybrid resin into a target zone of the subterranean formation. The target zone may have unconsolidated or weakly consolidated sand. The method then includes maintaining the treatment fluid in the target zone for a period of time such that the curable hybrid resin cures and forming a consolidated formation in the target zone.

    Abstract: A composition that includes porous polyurethane particles is provided. The porous particles are formed by curing an isocyanate component with water in the presence of a polyester filler and a hydrocarbon phase. A method for the preparation of porous polyurethane particles is also provided. The method includes providing a dispersed medium that contains a hydrocarbon phase, water, and a polyester filler. Then, an isocyanate component that is immiscible with the hydrocarbon phase may be added to the dispersed medium to form polyurethane prepolymer droplets, that may be cured by the water in the medium. An additional method for porous polymer particle preparation that includes providing a dispersed medium comprising a hydrocarbon phase, an isocyanate component that is immiscible in the hydrocarbon phase, and a polyester filler is provided. The dispersed medium may be agitated to form polyurethane prepolymer droplets, that may be cured by adding water.
