A multi-port flow selector manifold valve includes a plurality of inlet ports adapted to be coupled to a fluid source, a test outlet adapted to communicate with at least one of the plurality of inlet ports, and a production outlet adapted to communicate with at least at least one of the plurality of inlet ports. A flow path is rotatably disposed between the test outlet and the plurality of inlet ports such that the flow path is rotatably alignable with each of the plurality of inlet ports. The flow path includes an inlet flow path having a longitudinal direction of flow and adapted to communicate with one of the plurality of inlet ports, an outlet flow path having a direction of flow substantially parallel to the inlet direction of flow and adapted to communicate with the test outlet, and an offset portion disposed between the inlet flow path and the outlet flow path. The offset portion has a direction of flow with an angle of less than 90 degrees to the outlet direction of flow. The present invention further includes a manifold valve system using the previously described multi-port flow selector manifold valve and a method of use of the multi-port valve and manifold system.

Multi-port flow selector manifold valve and manifold system

A system for connecting multiple pipe lines includes a plurality of multi-port selector valves. Each valve includes a valve body having an inlet port module that includes a body adapted to connect to a fluid source and an outlet port module having a body with at least two outlet ports. Each of the outlet ports may connect to an outlet fluid destination. A port selector rotatably disposed in the valve body includes a rotatable member having a flow path there through that has a path inlet and a path outlet. The path outlet has a second flow direction substantially parallel to said first flow direction with an angle of less than 90 degrees to the first flow direction. An offset portion disposed between the first flow direction and the second flow direction has a longitudinal flow direction. An outlet valve line is adapted to connect one of the at least two outlet ports of a first valve of the plurality of valves to the inlet port of another of the plurality of valves.

Multiple line administration

An externally actuatable tieback connector for establishing fluid communication and force resisting connection of a conduit to a subsea wellhead having an internal locking geometry. The tieback connector has a body structure that is adapted for landing on a wellhead, with a part thereof extending into the wellhead and carrying a split lock ring. A lock energizing element, moveable relative to the body structure, has a locking position expanding the lock ring into locking and pre-load force transmitting engagement with the internal locking geometry of the wellhead and an unlocking position releasing the tieback connector from the wellhead. One or more drive members extend from the lock energizing element and are exposed externally of the connector body and wellhead for engagement and actuating movement by a lock actuating tool such as a ROV or the like.

Externally actuated subsea wellhead tieback connector

A wellhead system for petroleum producing wells comprises a &ldquo;stack-down&rdquo; casing hanger configuration. In this stack-down system, the hanger for each successively smaller diameter casing string is landed or &ldquo;nested&rdquo; within the hanger for the next larger casing string. This approach allows the pack-off for each casing hanger to be retrieved independently, thus allowing fluid communication to be established with any of the casing annuli after all of the casing strings and hangers have been installed. Thus the pressure in each annulus may be monitored while the well is in production mode.

Nested stack-down casing hanger system for subsea wellheads

The concentric tubing completion system of the present invention comprises a surface Christmas tree which is located on a surface structure, a tieback connector which is secured to a mudline wellhead that is installed at the upper end of a subsea well bore, a mudline tubing hanger which is supported in the tieback connector, and a pair of concentric tubing strings which are suspended from corresponding tubing hangers in the surface Christmas tree and connected to the mudline tubing hanger. The annulus between the concentric tubing strings communicates with a number of passages in the mudline tubing hanger which are connected to the tubing annulus below the mudline tubing hanger. Thus, lift gas or other fluids may be communicated between the surface christmas tree and the tubing annulus through this annulus between the concentric tubing strings.

Concentric tubing completion system

An adjustable tubular hanger for suspending a tubular string from a wellhead component is provided which includes an elongated body having a lower end adapted to be connected to the tubular string and an upper end portion including a plurality of axial annular grooves formed in the outer diameter surface thereof, each groove defining a downwardly facing support surface, and a support ring adapted to be positioned around the body in one of the grooves, the support ring having an upwardly facing load shoulder for engaging the support surface and a downwardly facing load surface for engaging a support shoulder formed in the wellhead component, whereby the elevation of the tubular hanger within the wellhead component can be adjusted depending on in which groove the support ring is positioned.

Adjustable hanger for tubular strings

An adjustable casing hanger for suspending a casing string from a wellhead is provided which includes an elongated tubular body having a lower end adapted to be connected to the casing string and an upper end portion including a plurality of axial annular grooves formed in the outer diameter surface thereof, each groove defining a downwardly facing support surface, and a support ring adapted to be positioned around the body in one of the grooves, the support ring having an upwardly facing load shoulder for engaging the support surface and a downwardly facing load surface for engaging a support shoulder formed in the wellhead, whereby the elevation of the casing hanger within the wellhead can be adjusted depending on in which groove the support ring is positioned. If desired or required by a particular application, one or more seals may be provided for sealing the annulus between the casing hanger and the wellhead, in which event the casing hanger preferably further includes a sealing surface pre-machined into each groove for engaging the seals.
