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.

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 fitting is disclosed that includes a body; a first flow passage extending through the body; and a second flow passage formed in the body to intersect the first flow passage. The first and second flow passages define first and second longitudinal center axes, respectively. In an exemplary embodiment, the fitting forms a portion of a manifold assembly of a frac system. In one aspect, the fitting is formed by a manufacturing process such that the body has a parting plane that is offset from, and parallel to, the first longitudinal center axis. The fitting may have a first varying wall thickness defined between the first flow passage and the external surface; and a second varying wall thickness defined between the second flow passage and the external surface. In another aspect, a curved surface is formed in the body at the intersection between the first and second flow passages.
