    摘要: Methods of diverting treating fluids in subterranean zones penetrated by well bores are provided. The methods basically comprise the following steps. A degradable particulate diverting material is placed in a subterranean zone that contains releasable water. A treating fluid is then introduced into the subterranean zone which is diverted by the degradable particulate diverting material therein. Thereafter, the degradable particulate diverting material is allowed to at least partially degrade in the presence of the released water in the subterranean zone.

    摘要: Method including the steps of providing a treatment fluid that comprises a base fluid and polymeric particulates and introducing the treatment fluid into a subterranean formation having a temperature above about 65° C. The polymeric particulates comprise a degradable polymer and a plasticizer and exhibit a Tg above about −15° C. When the polymeric particulates are placed into a subterranean formation having a temperature above about 65° C. they transform from rigid form to malleable form and are able to provide fluid loss, seal the rock surfaces for fluid diversion, or plug an area along the annulus of a well bore. The malleable particulates then degrade over time in the subterranean formation.

    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: 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.
