A method includes setting a tubular above a bottom of the well. The tubular having a float shoe attached to a distal end of the tubular and a controllable port penetrating a wall of the float shoe. The method further includes isolating a section of the annulus, opening the controllable port, and pumping cement through the controllable port into the section of the annulus to cement the annulus of the well.

A valve assembly for integration within a wellbore string disposed within a subterranean reservoir is provided. The valve assembly includes a valve housing having one or more injection ports for establishing fluid communication between a central passage and the reservoir. The valve assembly includes a valve sleeve operatively mounted within the valve housing and comprising a fluid channel adapted to establish fluid communication between the central passage and the injection ports, and configured to create a fluid flowrate restriction. The valve assembly has a flow adjuster connectable to the valve sleeve, and is selectively arranged to align an opening with the fluid channel and allow fluid to flow from the fluid channel through the opening to the injection port, wherein connecting the flow adjuster to the valve sleeve defines a flow length of the fluid channel to adjust the fluid restriction created by the fluid channel.

A liner string includes a liner hanger assembly and a liner hanger deployment assembly. The liner hanger assembly includes a liner hanger. The liner hanger includes a plurality of slips and a liner hanger actuation assembly configured to set the plurality of slips. The liner hanger deployment assembly is disposed within the liner hanger assembly. The liner hanger deployment assembly includes a setting tool configured to selectively allow fluid communication between a central bore of the setting tool and the liner hanger actuation assembly.

Ball valves, methods to close a ball valve, and methods to form a well barrier are discussed. A ball valve includes a valve housing and a ball that is rotatably movable from an open position to a closed position. The ball valve also includes an actuation mechanism operable to rotate the ball from the open position to the closed position, where a fluid passage of the ball is not aligned with a fluid passage of the valve housing while the ball is in the closed position. The ball valve further includes a sleeve disposed in the valve housing and operable to shift from a first position to a second position to actuate the actuation mechanism.

A filter assembly can include a filter element and a fluid inlet for fluid to flow through the filter element. The filter assembly can include bypass ports that are in a closed position from bypass port plugs until the filter screen becomes sufficiently clogged such that the fluid is restricted or prevented from flowing through the filter screen, which causes pressure to build up within the filter assembly. The increase in pressure can cause the bypass port plug to open the bypass ports such that fluid can flow through the bypass ports. The filter assembly can include a debris sleeve that partially or wholly surrounds the filter screen.

A well tool device includes a housing having an axial through bore; a sleeve section axially displaceable relative to the housing; a fluid flow preventing frangible disc; and an axial fluid passage bypassing the frangible disc when the well tool device is in an initial state, thereby allowing a fluid flow between a first location above the frangible disc and a second location below the frangible disc. The sleeve section includes an axial through bore aligned with the axial through bore of the housing. The axial fluid passage is closed when the well tool device is in a intermediate state. The fluid flow preventing frangible disc is provided in the bore of the sleeve section in sealing engagement with the sleeve section. The well tool device further includes a disc supporting device for supporting the frangible disc in relation to the sleeve section. The disc supporting device is releasably connected inside the sleeve section by a releasable connection device. The well tool device further includes a disintegration device disintegration of the frangible disc. The well tool device is in a final state when the frangible disc has been disintegrated by the disintegration device. The frangible disc is configured to be pushed axially relative to the sleeve section towards the disintegration device after release of the disc supporting device.

The present invention relates to a downhole apparatus and a valve arrangement for a downhole apparatus having a tubular body having first and second ports in a wall thereof; and a method of operating a valve arrangement of a downhole apparatus. The valve arrangement has at least one locked configuration and the first port provides fluid communication with a tool or a device which is a sand control element having at least one fluid deformable device. The present invention also provides a method of setting a sand control completion, extending the sand control filter element thereof to a wellbore surface and isolating the reservoir from an upper portion of the wellbore.

Isolation plugs may be installed in a wellbore flow control device to temporarily close a flow path therethrough. The isolation plugs may be installed in threaded openings often provided to for access to nozzles or other flow restrictors in the flow control devices. The isolation plugs may initially be locked in a closed configuration while being run in hole and may be unlocked in response to the application of a predetermined activation pressure. Once unlocked, the isolation plug may not immediately move to an open configuration but may continue holding pressure to permit circulation and washdown operations to be conducted. The activation pressure may be reduced to a second predetermined threshold to lock the isolation plug in the open configuration wherein flow is permitted through the flow control device.

A mill including a housing having a fluid bypass pathway, a milling feature at a longitudinal end of the housing, a chamber defined by the housing, and a piston disposed in communication with the chamber, the piston defining a fluid passageway initially aligned with the fluid bypass pathway, the piston responsive to pump pressure to move toward the milling feature, the movement misaligning the fluid passageway with the fluid bypass pathway.

A toe valve for use in a wellbore includes: a tubular mandrel; a housing extending along a periphery of the mandrel; couplings at longitudinal ends of the toe valve for assembly as part of a casing or liner string; a valve piston disposed in an annulus formed between the housing and the mandrel, movable between an open position and a closed position, and disposed between a valve port of the housing and a valve port of the mandrel in the closed position; an atmospheric chamber for facilitating movement of the valve piston to the open position; a vent port formed through the housing and in fluid communication with the atmospheric chamber; and a flow control device disposed in the vent port and operable to prevent fluid flow from the wellbore into the atmospheric chamber and allow fluid flow from the atmospheric chamber into the wellbore.
