Abstract
An ionic liquid may be used to inhibit the swelling and/or disintegration of clay in a subterranean formation. A subterranean clay-containing formation may be treated with the ionic liquid by contacting the formation with a well treatment composition containing the ionic liquid dispersed or dissolved in a carrier fluid. Damage to the formation caused by contact with the well treating composition is reduced or substantially eliminated.
