Abstract
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.
Claims20
A method comprising:
- providing a base material, wherein the base material comprises a clay mineral, a suspending agent, and a hydraulic cement;
- generating, from the base material, a base thixotropic slurry material having a density of 9 ppg to 16 ppg, a 10-minute static gel strength of between 83 lbf/100 ft2to 154 lbf/100 ft2at 80° F., and a compressive strength of between 100 psi and 120 psi at 100° F.;
- contacting a permeable zone in a wellbore with the base thixotropic slurry material;
- and
- performing a wellbore operation within the wellbore.
