Low-quality particulates and methods of making and using improved low-quality particulates

Abstract

A method of treating a subterranean formation, comprising: at least partially coating particulates with a first layer of a first curable resin and allowing the first curable resin to substantially cure; and then, at least partially coating the particulates with a second layer of a second curable resin; and allowing the second layer of the second curable resin to substantially cure; and then, slurrying the coated particulates into a treatment fluid and placing the slurry into a subterranean formation. Improved particulates suitable for use in subterranean formations, comprising low-quality particulates that have been at least partially coated with a first layer of a first curable resin and then at least partially coated with a second layer of a second curable resin and wherein the first layer of the first curable resin is allowed to substantially cure before the application of the second layer of the second curable resin.
