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： 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.
