Abstract

A treatment fluid and method for water shut-off applications containing an amine-functionalized solid support, an epoxy resin, a second curing agent, and a carrier fluid. Prior to use of the treatment fluid, the amine-functionalized solid support has reacted with carbon dioxide to produce a carbamate-functionalized solid support. The treatment fluid is introduced into a geological formation with high-permeability pathways, curing the epoxy resin, and sealing these pathways.
