Abstract: Proppant particles are made by coating the particles with a coating composition that contains a polyisocyanate, followed by applying and reacting a compound that is isocyanate-reactive and also has acrylate or methacrylate groups. The resulting proppant particles bond together when emplaced in a subterranean formation to form a proppant pack that resists flowback. Good bonding is seen even at somewhat low formation temperatures.

Abstract: Polyurethanes are made by curing a reaction mixture containing a polyether polyol that contains residues of a zinc hexacyanocobaltate catalyst complex. The reaction mixture contains certain chelating agents in small quantities. The amount of cobalt that is extractable from the polyurethane is reduced.

Abstract: Hydroxyl-containing copolymers of butylene oxide and ethylene oxide having a hydroxyl equivalent weight of at least 150, an average of 1.8 to 6 hydroxyl groups per molecule of which hydroxyl groups at least 70% are primary hydroxyl groups and an oxyethylene content of no greater than 10% by weight based on the weight of the copolymer, are useful for making polyurethanes. These polyols are characterized by high reactivity and fast curing times. Polyurethanes made using these polyols have excellent mechanical properties and are highly hydrophobic.
