An apparatus for use in a wellbore contains a flow control device for use in a wellbore that includes a bore that provides a first flow path and a second flow path via an annulus around the first flow path. The apparatus further includes a closing device that closes the second flow path when the closing device is mechanically moved in a first direction and an opening device that opens the second flow path when a fluid under pressure is supplied to the annulus when a valve is closed.

Wellbore strings containing annular flow valves and methods of use thereof

An isolation system is disclosed that contains: a lower wet connect portion, a central production tubing, an isolation device associated with the central production tubing, and at least one communication line, wherein the at least one communication line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further, a method for isolating a lower completion is disclosed that includes: conveying an isolation assembly to the lower completion, the isolation assembly including: a lower wet isolation device; and routing the at least one communication line through an inside diameter of the isolation device. Further a completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.

Wellbore isolation system with communication lines

An isolation system is disclosed that contains a lower wet connect portion; a central production tubing; an isolation device associated with the central production tubing, and at least one control line. Further at least one control line is associated with the lower wet connect portion and is disposed through an inside diameter of the isolation device. Further method for isolating a lower completion is disclosed that includes conveying an isolation assembly to the lower completion, the isolation assembly including a lower wet connect portion, at least one control line, a central production tubing, and an isolation device, and routing the at least one control line through an inside diameter of the isolation device. Further completion system is disclosed that contains a lower completion system and an isolation system associated with the lower completion system.

A production control system having a series of nested tubular members including at least one axial flow channel and at least two annular flow channels. At least one valve configured and positioned to control flow from each flow channel is provided. A production apparatus having a series of nested tubulars connected to one another such that at least an axial flow channel and at least two annular flow channels are formed. A valve is associated with each flow channel and is configured to independently control flow from each flow channels. A method for controlling commingling of flows from multiple zones. The method includes containing flows from different zones to individual concentric flow channels in a nested tubular arrangement and selectively commingling one or more of the flows by setting at least one valve associated with each channel to a closed position or one of an infinite number of flow positions.

Multiple zone downhole intelligent flow control valve system and method for controlling commingling of flows from multiple zones

A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion. The various completion and/or production activities can also be accomplished using the auxiliary conduits such as actuation of down hole flow control devices, chemical injection, pressure measurement, distributed temperature sensing through fiber optics, as well as other down hole parameters.

Method of providing hydraulic/fiber conduits adjacent bottom hole assemblies for multi-step completions

A subsurface safety valve has a tubular valve housing, a valve closure member movable between an open and a closed position, an axially shiftable flow tube for opening the valve closure member, a spring for biasing the flow tube to a closed position, a piston and cylinder assembly to move the flow tube to an open position, and a plug inserted within an opening in the valve housing. This opening is in fluid communication with the piston and cylinder assembly. The plug is adapted to be displaced from the opening to lock out the safety valve, and to establish secondary hydraulic fluid communication with an interior of the safety valve in order to operate secondary tools, such as wireline set secondary valves, inserted into the locked out safety valve.
