    摘要： Provided are example methods and systems for treating a subterranean formation. An example method comprises alternately pumping a volume of proppant-laden fluid and a volume of spacer fluid into a wellbore penetrating a subterranean formation. The proppant-laden fluid comprises an aqueous fluid and proppant. The spacer fluid comprises an aqueous fluid. At least one of the proppant-laden fluid or the spacer fluid comprises a synthetic clay. The volume of proppant-laden fluid and the volume of spacer fluid may be pumped in any order. The method further comprises repeating the alternately pumping a volume of proppant-laden fluid and a volume of spacer fluid at least once.

    摘要： The transport and suspension of proppant in a fracturing fluid used to fracture a subterranean formation is improved by incorporating a buoyant additive into a carrier fluid that also comprises a proppant. The buoyant additive has a surface, in one non-limiting embodiment a hydrophobic surface or a superhydrophobic surface, and the buoyant additive is present in an amount effective to suspend at least a portion of the proppant in the fracturing fluid. The buoyant additive has had its surface modified with a surface modifying agent, which may include, but is not necessarily limited to, wax, silica, an organo silane, a siliconate, a silicate, a silsesquioxane, phosphonic acids, transition metal oxides, post-transition metal oxides, silicon, and combinations thereof.

    摘要： Methods and systems for restimulating a previously fractured subterranean formation penetrated by a wellbore are described. The methods include plugging existing perforations in an outer casing and existing fractures in the formation with a diverting agent, placing an inner casing in the wellbore while the existing perforations and existing fractures are plugged with the diverting agent, perforating the inner casing and the outer casing to form new perforations, and pumping a fluid through the new perforations to create new fractures in the formation.

    摘要： Compositions, methods, and systems including an encapsulated additive comprising a treatment fluid additive at least partially encapsulated by an encapsulating material. The encapsulated additive has a target release profile for release of the treatment fluid additive from the encapsulating material in a specific wellbore environment. The encapsulating material is selected to achieve the target release profile, the target release profile being based on one or more conditions selected from the group consisting of: (1) a target anisotropic pressure that is greater than both an injection anisotropic pressure and an injection isotropic pressure, (2) an erosion number, (3) a temperature-driven degradation, (4) a pressure-driven degradation, (5) an amphiphilic water dispersibility, (6) an amphiphilic oil dispersibility, (7) a chemical flood degradation, (8) a water ingress value, and, (9) a radiation-driven degradation.
