Abstract: A method to provide a fractured subterranean formation is provided, the method including the steps of: providing a wellbore from a surface location to the subterranean formation; applying a friction reduction treatment to at least a portion of an inside surface of a casing; cementing the casing with the applied friction reduction treatment into at least a portion of the wellbore; and pumping into the wellbore a fluid at a pressure that exceeds a fracture pressure of the subterranean formation thereby forming at least one fracture within the subterranean formation wherein the fluid is in contact with at least a portion of the inside surface of the casing with the applied friction reduction treatment.

Abstract: A method of treating a subterranean formation via well bore may include introducing a plurality of particles into the subterranean formation via the well bore, each particle having a substrate and a layer of cement on the substrate. The cement may be in a state of suspended hydration and the method may include introducing moisture to the subterranean formation via the well bore. The method may also include allowing the particles and the moisture to contact one another. Contact between the particles and the moisture may cause the cement to move from a state of suspended hydration to a state of secondary hydration.

Abstract translation: 通过井眼处理地层的方法可以包括通过井眼将多个颗粒引入地下地层，每个颗粒在基底上具有基底和一层水泥。 水泥可以处于悬浮水合的状态，并且该方法可以包括通过井孔将水分引入到地下地层中。 该方法还可以包括允许颗粒和湿气彼此接触。 颗粒和水分之间的接触可能导致水泥从悬浮水合状态移动到二次水合状态。

Abstract: A method for underdisplacing fracture proppant in a well bore. The method can include providing a set retainer having a passage configured to receive a wiper plug. The method may also include installing the set retainer in the well bore and injecting a proppant-laden fluid into the well bore, through the passage of the set retainer and through a perforation to create the fracture. The method may include providing a wiper plug configured to be received in the passage of the set retainer. The method may also include inserting the wiper plug into the well bore and allowing the wiper plug to wipe a portion of the proppant-laden fluid past the set retainer and into the fracture. Additionally, the method may include allowing the set retainer to receive the wiper plug.
