Abstract: A fracturing manifold module of a fracturing manifold system for controlling the flow of fracturing fluid from a shared manifold trunk line to a plurality of wellheads each adapted for fracturing a well. The fracturing manifold module includes a transport skid adapted to be ground supported and a flow control unit supported on the transport skid and including an inlet adapted for connection along an axis of the shared manifold trunk line, an outlet adapted for connection to one of the plurality of wellheads via one or more fluid conduits, and one or more flow control valves between the inlet and the outlet. The transport skid and the flow control unit are connected together to provide for rotation of the flow control unit relative to the transport skid in a generally horizontal x-y plane relative to the ground, said rotation being about a z-axis perpendicular to the x-y plane to provide for adjustable connection to the fracturing manifold system at one or both of the inlet and the outlet.

Abstract: A ball injector for connecting below the frac head of a frac tree to accommodate and sequentially drop a ball into the axial passageway of the frac tree. The ball injector has an axial passage of an injector housing aligned with the axial passageway of the frac tree. A ball cartridge assembly stores one or more balls and sequentially delivers one ball to a port in the ball cartridge assembly. A ball launch side arm extends from the injector housing and forms a ball launch passageway communicating between the ball cartridge port and the axial passage. A first valve member in the ball launch passageway is opened to pass the ball into the axial passage, and is closed to isolate the ball cartridge assembly from a pressure in the axial passage. A second valve member between the first valve member and the ball cartridge assembly may be included to form a pressure isolation chamber between the valve members. Embodiments of ball cartridge assemblies to horizontally store a plurality of balls is provided.
