Abstract: A ball valve assembly includes a ball configured to rotate between an open position and a closed position. The ball valve assembly also includes a cradle having a ball-facing surface. The ball-facing surface faces the ball and is positioned at an end of a fluid passage through the cradle. In addition, the cradle is configured to rotatably support the ball to enable the ball to rotate between the open position and the closed position, and the cradle is configured to block movement of the ball toward the ball-facing surface to establish a separation distance between the ball and the ball-facing surface.

Abstract: A system includes a well testing apparatus and a mobile device to be carried by an operator of the well testing apparatus. The well testing apparatus can include a separator, a well control assembly upstream of the separator, a fluid management assembly downstream of the separator, and data acquisition devices positioned to collect data about operation of the well testing apparatus. The mobile device can display information about the operation of the well testing apparatus based on the collected data and enables mobile monitoring of the operation of the well testing apparatus by the operator as the operator moves about the well testing apparatus. Additional systems, methods, and devices are also disclosed.

Abstract: A ball valve assembly includes a ball having a fluid pathway and a leading edge portion. The ball is configured to rotate between an open position and a closed position, the fluid pathway is configured to align with a fluid passage while the ball is in the open position, and the fluid pathway is configured to be offset from the fluid passage while the ball is in the closed position. Furthermore, the leading edge portion includes a first leading edge configured to cut a line extending through the fluid pathway as the ball rotates from the open position to the closed position, the leading edge portion includes a second leading edge configured to engage a seal of the ball valve assembly as the ball rotates from the open position to the closed position, and the first leading edge is positioned radially inward from the second leading edge.

Abstract: A well testing apparatus includes tank manifold skids connected to tanks, a pump manifold skid, and a control system. Each tank manifold skid includes first pipework, second pipework, and valves. The first pipework of each tank manifold skid cooperates with the first pipework of another tank manifold skid to enable fluid communication between the tank manifold skids. The second pipework of each tank manifold skid enables fluid communication between the first pipework and a connected tank, while the valves can control flow through the second pipework to the tank. The pump manifold skid is coupled to the tank manifold skids and includes fluid manifolds, pumps, and valves. The control system includes a control unit for remotely actuating the valves to selectively control fluid flow from a separator to the tanks via the pump manifold skid and the tank manifold skids. Additional systems, methods, and devices are also disclosed.

Abstract: A subsea valve system for use in a subsea landing string includes a subsea valve and an external manifold in fluid communication with the subsea valve. The external manifold includes a cylinder, a split manifold piston, an above bore inlet that is configured to be exposed to an above bore pressure, a below bore inlet that is configured to be exposed to a below bore pressure, and an open chamber outlet. The split manifold piston is configured to move within the cylinder to fluidly couple the above bore inlet to the open chamber outlet to enable pump through functionality while a respective force exerted on the manifold piston by the above bore pressure is greater than a respective force exerted on the manifold piston by the below bore pressure.

Abstract: A well testing apparatus includes a separator, a well control assembly upstream of the separator, and a fluid management assembly downstream of the separator. At least one of the well control assembly or the fluid management assembly can include flow control equipment, a controller for controlling actuation of the flow control equipment, and a human-machine interface that enables an operator to monitor or control operation of the well control assembly or the fluid management assembly. The human-machine interface can be positioned with the flow control equipment so as to enable an operator to directly sense contextual clues about operation of the well control assembly or the fluid management assembly independent of the human-machine interface while using the human-machine interface. Additional systems, methods, and devices are also disclosed.
