摘要： Disclosed herein are swellable and degradable sand plug systems used in wellbores and methods for using the systems in treating wellbores. The slurry composition includes a carrier fluid and a granular borate source material, where the borate source material is at least partially dehydrated or anhydrous. The carrier fluid may be non-aqueous fluid or, in some compositions, an aqueous fluid. The slurry composition is allowed to settle in a horizontal wellbore and at least partially fill at least a portion of the wellbore in a direction vertical to the wellbore, and is exposed to a sufficient amount of aqueous fluid to expand and substantially fill at least a portion of the wellbore, thereby plugging the wellbore. The slurry composition may be exposed to a sufficient amount of aqueous liquid to at least partially dissolve the expanded slurry composition, thereby at least partially removing the plug from the wellbore.

摘要： Reduction of the water permeability within a subterranean formation, particularly within a proppant pack or a gravel pack, can be achieved through the use of a relative permeability modifier (RPM) coated on a particulate material. Methods for reducing the water permeability include providing RPM-coated particulates that contain a RPM coating on the particulates, and placing a treatment fluid containing a base fluid and the RPM-coated particulates in at least a portion of a subterranean formation. The treatment fluid can also contain a companion polymer that serves to further reduce the water permeability compared to that achievable when using the RPM alone.

摘要： This invention relates to an aqueous-swellable and degradable diverting system and the use of the system in treating a subterranean formation penetrated by a wellbore. The diverting system comprises a carrier fluid and a partially dehydrated or anhydrous borate source material that does not swell or does not swell substantially when placed in contact with the carrier fluid. The carrier fluid is capable of carrying and placing the borate source material into a stimulation network substantially distanced from a wellbore. The carrier fluid may be a non-aqueous fluid, or when the average size of the borate source material is sufficient large, the carrier fluid may also be an aqueous fluid. Exposure of the diverting composition to sufficient amount of aqueous fluid swells the borate source material, bridges a desired portion of the stimulation network and then dissolves at least a portion of the diverting composition. The diverting techniques of the invention allow for treatment in a subterranean formation to be diverted to a previously untreated portion of the formation, in particular a portion of the formation that is significantly distanced from the wellbore.
