GELLABLE TREATMENT FLUIDS COMPRISING QUATERNARY AMMONIUM SALT GEL-TIME MODIFIERS AND METHODS FOR USE THEREOF.

摘要

Methods for reducing the amount of water produced from a subterranean formation can include the use of a gellable treatment fluid that comprises a quaternary ammonium salt as a gel-time modifier. The gellable treatment fluids can comprise an aqueous base fluid, a base polymer comprising an acrylamide monomer unit, an organic crosslinking agent, and a gel-time modifier comprising a quaternary ammonium salt.
