Abstract

A method of servicing a wellbore penetrating a subterranean formation with a thixotropic cement composition is provided. The thixotropic cement composition includes a cementitious material, silica fume, graphene oxide, and an aqueous fluid, can have a 10-minute gel strength of from about 20 lbf/100 ftto about 300 lbf/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, the thixotropic cement composition can have a higher 10-minute gel strength than a reference composition absent the graphene oxide.
