Abstract
An improved resin coated particle comprises a particulate substrate, an inner coating of a curable resin and an outer coating of a substantially cured resin. These improved resin coated particles are produced by first coating the substrate with a reactive resin. A second or outer coating of a resin is then coated over the inner curable resin coating and subjected to conditions of time and temperature sufficient to substantially cure said outer coating while the inner coating remains curable. The particles can be used in a method for treating subterranean formations, which comprises placing in or adjacent to the formation a quantity of the resin coated particle and allowing them to cure into a high strength permeable mass in the formation.
