Abstract

An aqueous composition has been developed to treat subterranean formations whereby the compositions can maintain for a period of time a sufficient viscosity to function as a hydraulic fluid and optionally to support particulate matter. Subsequently, the viscosity of the composition decreases to facilitate the removal of the composition.
