摘要： The present invention provides oil based compositions and methods of using the compositions for temporarily sealing subterranean zones. The compositions are basically comprised of oil, a hydratable polymer, an organophilic clay, a water-swellable clay, and an acid soluble material such as calcium carbonate. These compositions will form a viscous gel when contacted with water. The gelled mass may then be dissolved with an acidic fluid, such as 15% hydrochloric acid.

摘要： A dry, agglomerated cement material, a method of preparing the dry, agglomerated cement material, a method of cementing, and an apparatus for agglomerating particulate materials. The dry, agglomerated cement material comprises a plurality of particles of a cement bonded together by a water-soluble binder material. The dry, agglomerated cement material is prepared by depositing the water-soluble binder material on the particles such that the binder material bonds the particles together. The inventive agglomerated cement material can be conveniently transported by both pneumatic and non-pneumatic means. The method of cementing comprises the step of mixing the agglomerated cement material with water to form a cement slurry. The agglomerating apparatus comprises: a vessel; a cone blender associated with the vessel such that the cone blender is operable for fluidizing a particulate material placed in the vessel; a fluidizing gas delivery system or delivering a fluidizing gas to the cone blender; and a binder solution delivery system for delivering a binder solution into the vessel.

摘要： Set retarded cement compositions which are substantially non-thinning at high temperatures are provided. The compositions are comprised of hydraulic cement, sufficient water to form a pumpable slurry, a set retarder and a galactomannan gum which has been treated with a hydrophobing agent whereby the hydration rate of the gum is retarded at temperatures below about 120.degree. F. and at pH levels above about 10. The delayed hydration of the treated gum offsets the thinning of the cement compositions at temperatures above about 120.degree. F. Methods of cementing subterranean zones penetrated by well bores utilizing the cement compositions are also provided.
