ABSTRACT:
Methods and compositions for reducing the viscosity of subterranean treatment fluids that comprise a gelling agent utilizing breakers that comprise hydroquinone and/or a derivative thereof. In one embodiment, the present invention provides a method comprising: providing a treatment fluid that comprises an aqueous base fluid and a gelling agent; providing a breaker that comprises a hydroquinone component; allowing the breaker to interact with the treatment fluid; and allowing the breaker to at least partially reduce the viscosity of the treatment fluid.
