Thixotropic Cement Slurry with Graphene Oxide

Abstract: disclosed herein is a method of servicing a wellbore penetrating a subterranean formation with a thixotropic cement composition. the thixotropic cement composition comprises a cementitious material, silica fume, graphene oxide, and an aqueous fluid, can have a 10-minute gel strength of from about 20 lb/100 ftto about 300 lb/100 ft, and can be used to service a wellbore (e.g., to reduce lost circulation in the wellbore). by incorporating graphene oxide into the thixotropic cement composition as disclosed herein, the thixotropic cement composition can have a higher 10-minute gel strength than a reference composition absent the graphene oxide.
