A downhole tool including a tubular member having an outer surface and an inner surface defining a flow bore. An expandable member is arranged on the outer surface. The expandable member is selectively radially outwardly expandable. An activation mechanism is operatively connected to the expandable member. The activation mechanism is operable to radially outwardly expand the expandable member. A control line extends along the outer surface and over the expandable member. A control line guidance system is operable to shift the control line radially outwardly from the outer surface.

Control line guidance system for downhole applications

A backup including a radially inwardly disposed circumferentially continuous ring; a radially outwardly disposed circumferentially discontinuous ring, the circumferentially discontinuous ring comprising a plurality of segments arranged to overlap adjacent ones thereof about a circumference of the circumferentially discontinuous ring.

Multi-layer backup ring

Ratchet locking segments permit one direction relative movement and then prevent reverse movement to hold a set position of a tool. The segments are axially supported in a surrounding housing using an exterior profile on each segment meshing with a conforming profile on the outer housing. The meshing is loose to allow the segments the ability to move radially while supported axially. Biasing of opposed ratcheting segments toward each other is provided by a spring or springs at opposed axial ends of each segment or within the exterior profile between the axial ends. The end biasing can be done with coiled springs or bent tabs that store potential energy when assembled or with wave springs between the segment outer profile and a surrounding outer housing.

Lock ring segments biased into locked position while retained in position with an exterior profile

A backup ring assembly has a plurality of radially offset ring members including an outermost ring member formed from plurality of axially extending segments. Each of the plurality of axially extending segments includes an outer surface. A first interlock member support is coupled to the outer surface of one of the plurality of axially extending segments of the outer most ring member. A second interlock member support is coupled to the outer surface of an another one of the plurality of axially extending segments of the outermost ring member. An interlock member includes a first end supported at the first interlock member support and a second end supported at the second interlock member support. The interlock member restrains radially outward expansion of the ring and circumferential expansion of a gap extending between the one of the axially extending segments and the another one of the axially extending segments.

Multi-layer backup ring including interlock members

A production sting has a premium thread preferably VAM or similar for threading into a packer extension without the need for a seal stack to engage a seal bore in the extension. The seal bore use becomes optional and a metal to metal seal is provided by the premium thread whether the string is in compression or tension. Another adjacent left hand square thread is provided in the packer extension to land accessory tools or for removal of the packer after the packer is released in a variety of known ways. Either the premium thread or the left hand thread can be in the uphole position on the packer extension.

A mechanically-set packer system for use in a wellbore may include a packer assembly. The packer assembly may include a first ring and a second ring. The packer assembly may also include a packing element positioned between the first ring and the second ring. The packer system may include a mandrel having an interior and an exterior. The packer assembly may be configured to slide onto the exterior of the mandrel. The packer system may further include a line configured to run between the exterior of the mandrel and an interior of the packing element.

Open-hole mechanical packer with external feed through and racked packing system

A tool for use in a wellbore that includes a mandrel having an interior and an exterior with a plurality of keyed ring members along the exterior of the mandrel having an external line that runs the length of the tool. The tool may include a packing element positioned between at least a first keyed ring member and a keyed second ring member. A line is run between the exterior of the mandrel and an interior of the packing element, through an inner bore of the first ring, and through an inner bore of the second ring. Key members may be removed from the ring members to permit the insertion of the line through the packer system. The key members may be removed to removal of a ring component from the packer system. The key members and ring component enable a tool to be constructed onsite at a wellbore.

Locking keyed components for downhole tools

An articulated debris barrier folds on itself to extend radially to span a surrounding annular gap when the tool associated with it is set. The debris barrier can be used with a packer or bridge plug. The set position of the packer or plug is locked and another lock holds the extended position of the debris barrier. The debris barrier lock can be a snap ring that extends into a groove brought into alignment with it during the setting. Alternatively the lock for the debris barrier can be a body lock ring. In either case, release and retrieval of the packer or plug involves undermining of the locking feature for the debris barrier so that the debris barrier can extend while retracting from the borehole wall so that the barrier and the associated packer or plug can be removed together.
