CONTROLLING PRODUCTION OF WATER IN SUBTERRANEAN FORMATIONS

摘要

Methods, compositions, and systems that may be used for the selective reduction of water permeability of subterranean formations using hydrogel polymer materials are provided. An embodiment of the present disclosure is a method comprising: providing a treatment fluid comprising a carrier fluid and a hydrogel polymer comprising the reaction product of a polysaccharide and a derivative of acrylic acid; and introducing the treatment fluid into a wellbore that penetrates at least a portion of a subterranean formation.
