METHODS AND COMPOSITIONS FOR TREATING THIEF ZONES IN CARBONATE FORMATIONS USING CROSSLINKED POLYMERIC SYSTEMS WITH GRAPHENE OXIDE JANUS NANOSHEETS CROSSLINKER
METHODS AND COMPOSITIONS FOR TREATING THIEF ZONES IN CARBONATE FORMATIONS USING CROSSLINKED POLYMERIC SYSTEMS WITH GRAPHENE OXIDE JANUS NANOSHEETS CROSSLINKER
A chemical gel system having a polymer and a graphene oxide Janus nanosheets crosslinker for treating thief zones in carbonate formations. The polymer and graphene oxide Janus nanosheets crosslinker may form a crosslinked polymer gel to reduce or prevent water production via thief zones during hydrocarbon production. The graphene oxide Janus nanosheets crosslinker includes a first side having negatively charged functional groups and a second side having amines. The negatively charged functional groups may include carboxyl groups, negatively charged oxygen groups, and hydroxyl groups. Methods of reducing water production in a thief zone using the graphene oxide J anus nanosheets crosslinker and methods of manufacturing the graphene oxide Janus nanosheets crosslinker are also provided.
