An apparatus, system, and method of use that enables control of fluid flow in a wellbore drill string with a pilot. The apparatus comprises a pusher rod with a bore for fluid flow contacting a rotatable ball with an internal bore comprising at least one pilot, wherein the seat between the pusher rod and the interior of the tubular prevents fluid flow. Pressure changes on the pusher rod rotate the bore of the ball in and out of contact with the bore of the pusher rod, to enable or prevent fluid flow, respectively. A method of use opens the ball by exerting pressure and/or force on the pusher rod to enable fluid through the ball by aligning the internal bores. Fluid flow is stopped by pressure exerted on the bottom of the ball causing the ball to rotate whereby the internal bore of the pusher rod is connected to the exterior surface of the ball. An accumulator can control the operations of the valve by selectively exerting pressure and/or fluid flow on the pusher rod.

A plugging assembly includes a plug and a setting tool attached directly to the plug, wherein the plug includes an elongate core with an uphole end and a downhole end opposite the uphole end, and a sealing element disposed fully around the core to seal against the casing. The plug additionally includes an anchoring system for anchoring the plug to the casing in a fixed position, a compression fitting disposed around the core at or near the uphole end of the core, and a nose at the downhole end of the core. The setting tool includes an elongate housing extending between an uphole end and a downhole end opposite the uphole end, an open passageway extending from the uphole end to the downhole end of the housing, and the downhole end of the housing is aligned to directly engage the compression fitting of the plug.

Valve assemblies are disclosed for use in the oil and gas industry. A disclosed valve assembly includes a housing having a bore; a valve member arranged within the housing which is movable relative to the bore between open and closed positions. The valve member includes a cutting feature and a sealing surface; a cutting component that cooperates with the cutting feature when the valve member is in moved to the closed position; a first seal element arranged within the housing and providing a first seal relative to the sealing surface; and a second seal element arranged within the housing and providing a second seal relative to the sealing surface. The second seal element is movable relative to the housing bore between first and second positions. A corresponding method of controlling communication along a bore of a housing is also disclosed.

A downhole tool is hydraulically actuated. The actuation system includes an indexing track and pin assembly. An operator may lose track of the location of the track and pin assembly. The indexing track and pin assembly includes a shifting indexing path. By moving the indexing track and pin assembly through the shifting indexing path, the indexing track and pin assembly will move to a known position without needing any pressure measurement.

A valve assembly (1) has a valve (14), for example a flapper valve, that is contained within an axially movable valve housing (11) in the form of a cartridge (10) that is received within the bore of a tubular member (5). More than one cartridge (10) may be connected in series. The valve (14) and cartridge (10) are pivotally connected (13) and axial movement of the cartridge (10) pivots the valve (14) around this connection (13) to open or close the valve (14). The valve assembly (1) can be actuated by an actuator assembly (50) having an actuator (61) for actuating the valve (14), and a resettable shuttle device (80) that retains the actuator (61) in different configurations within the actuator assembly (50). The actuator (61) can be moved relative to the valve (14), engaging the shuttle device (80) and changing the configuration of the shuttle device (80).

Disclosed is a gravel pack service tool that utilizes an internal closure device to set a packer. One disclosed system includes a completion string including at least one packer, a service tool configured to be arranged within the completion string and having an interior that provides a flow path for fluids and a crossover tool, and a closure device arranged within the flow path and being actuatable between an open position and a closed position in response to a signature pressure pulse detected by the closure device, wherein, when the closure device is in the open position, the fluids are able to bypass the closure device and flow to lower portions of the service tool, and wherein, when the closure device is in the closed position, the fluids are prevented from bypassing the closure device and a pressure within the service tool is increased to set the at least one packer.
