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, maltodextrin, and an aqueous fluid, has a 10-minute gel strength of from about 30 lbf/100 ftto about 300 lbf/100 ft, and can be used to reduce lost circulation in the wellbore. By incorporating maltodextrin into the thixotropic cement composition as disclosed herein, the thixotropic cement composition can have a similar 10-minute gel strength and an increased thickening time when compared to a reference composition.

Methods of making and using a thixotropic cement composition

A thixotropic slurry material can be used in a wellbore during a wellbore operation. The wellbore operation can include a drilling operation, a cementing operation, or any other suitable operation that may include injecting a liquid material into the wellbore. The thixotropic slurry material can be a mixture of a cement, a clay mineral, and a suspending agent and can be injected into a wellbore during the wellbore operation.
