摘要： An apparatus according to which a subterranean formation in which a wellbore extends is hydraulically fractured, the apparatus comprising first and second manifolds, the first manifold including first and second flow lines adapted to be in fluid communication with first and second pumps, respectively, the first pump being adapted to pressurize fluid received from the first flow line, and the second pump being adapted to pressurize fluid received from the second flow line, and the second manifold including a third flow line adapted to convey pressurized fluid from the first and second pumps to the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends. The apparatus is adapted to be connected to another apparatus used to hydraulically fracture the subterranean formation in which the wellbore extends by moving one, or both, of the first and second flow lines relative to the third flow line.

摘要： A plug valve including a valve body defining an internal cavity, a first passage, and a second passage, a plug defining a third passage and being rotatable within the internal cavity, and an insert extending within the internal cavity between the valve body and the plug. The insert defines an interior surface and an opening aligned with the first passage of the valve body. The insert may also define a sealing surface extending around the opening and standing in relief against the interior surface to sealingly engage the plug. In addition to, or instead of, the sealing surface, the insert may define a projection at least partially defining the interior surface. In addition, a boot may be connected to the valve body and interlocked with the projection to prevent, or at least reduce, rotation of the insert relative to the valve body when the plug rotates within the internal cavity.

摘要： A valve assembly adapted for use in oil and gas operations. In one aspect, the valve assembly includes a valve body defining an internal region, an inlet passageway, and an outlet passageway, the inlet and outlet passageways extending into the internal region; a valve seat connected to the valve body and defining a fluid passageway; a clapper extending within the internal region and defining an annular groove; and a seal extending within the annular groove of the clapper and adapted to sealingly engage the valve seat. In an example embodiment, the clapper is actuable between an open configuration, in which fluid flow is permitted through the fluid passageway; and a closed configuration, in which the seal sealingly engages the valve seat to at least partially restrict fluid flow through the fluid passageway.
