Abstract
A method of stabilizing one or more clays within a subterranean formation comprises forming at least one treatment fluid comprising anionic silica particles, cationic silica particles, and at least one base material. The at least one treatment fluid is provided into a subterranean formation containing clay particles to attach at least a portion of the anionic silica particles and the cationic silica particles to surfaces of the clay particles and form stabilized clay particles. A method of treating one or more clays contained within a subterranean formation, and a treatment fluid for a subterranean formation.
