摘要： Encapsulated water soluble chemicals for use in controlled time release applications, methods of encapsulating the chemicals and methods of using the encapsulated chemicals are provided. The methods of encapsulating the chemicals are basically comprised of forming a first coating of a dry hydrophobic film forming material or a sparingly soluble material which provides a dry shield on the chemical and then forming a second coating of a porous cross-linked hydrophilic polymer on the first coating which prevents the substantial dissolution of the resulting encapsulated chemical for a selected period of time.

摘要： Methods of controlling the rates of release of chemical additives into treating fluids are provided by the present invention. The methods are basically comprised of causing a chemical additive in liquid form to be absorbed into a porous solid material whereby the chemical additive is encapsulated thereby and when the resulting encapsulated chemical additive is combined with the treating fluid, the chemical additive is slowly released into the treating fluid. After being encapsulated, the liquid chemical additive is combined with the treating fluid and the treating fluid containing the encapsulated chemical additive is introduced into a well.

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.
