A method of servicing a wellbore in contact with a subterranean formation comprising placing an aqueous composition comprising a mud displacement fluid and a clay inhibitor into the wellbore. An aqueous composition for servicing a wellbore comprising a mud displacement fluid and a clay inhibitor. A method of servicing a wellbore comprising introducing an aqueous wellbore servicing fluid comprising a clay inhibitor, thereby inhibiting the swelling of an argillaceous subterranean formation penetrated by the wellbore.

Servicing a wellbore with an aqueous based fluid comprising a clay inhibitor

This invention relates to a method of repairing holes, channels, voids and microannuli in a cement sheath situated in the annular space between a casing and the wall of a wellbore penetrating a subterranean earth formation, which method involves the use of a hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The cement, which is utilized in a water slurry, has a low density, good thixotropic properties and, in one embodiment, expansive characteristics.

Repair of microannuli and cement sheath

This invention relates to a method of cementing a cylinder in a bore, such as a casing in a wellbore, which method involves the use of a hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The cement which is utilized in a water slurry, has a low density, good thixotropic properties and, in one embodiment, expansive characteristics.

Primary cementing

This invention relates to a method of repairing a hole in and thereby terminating the undesirable flow of fluid through a hole in a casing disposed in a wellbore penetrating a subterranean earth formation which method involves the same use of a hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The cement, which is utilized in a water slurry, has a low density, good thixotropic properties and, in one embodiment, expansive characteristics.

Repairing leaks in casings

This invention relates to a method of changing the direction of drilling a well bore wherein a cement plug is formed in the well bore at a location therein where the direction of drilling is to be changed and a pilot hole is drilled in the plug. The cement plug is formed using a slurry containing hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The use of such finely divided hydraulic cement significantly reduces the waiting time required for the slurry to develop sufficient compressive strength.
