Abstract: Methods of treating a portion of a wellbore include introducing a first treatment fluid to a far-field area of a subterranean formation, the first treatment fluid comprising a first proppant, and introducing a second treatment fluid to a near wellbore area of the subterranean formation, the second treatment fluid comprising a second proppant different from the first proppant. The method includes reducing flowback of the first proppant into the wellbore while permitting liquid passage into the wellbore by forming a near wellbore barrier containing the second proppant.

Abstract: A pressure wave is generated within a first well extending into a subterranean formation. A pressure response associated with the pressure wave is detected from a second well extending into the formation. Information is then determined, based on the pressure response in the second well, wherein the information is associated with at least one of the formation and a fracture connected to at least one of the first well and the second well.

Abstract: Methods include pumping a fracturing pad fluid into a subterranean formation under conditions of sufficient rate and pressure to create at least one fracture in the subterranean formation, the fracturing pad fluid including a carrier fluid and a plurality of bridging particles, the bridging particles forming a bridge in a fracture tip of a far field region of the formation. Methods further include pumping a first plurality of fibers into the subterranean formation to form a low permeability plug with the bridging particles, and pumping a proppant fluid comprising a plurality of proppant particles.
