Systems and methods of the present disclosure relate to downhole tools including expandable liner hangers that used a foam member to increase fluid volume in voids defined by the hanger and the casing. A system comprises a downhole tool comprising a tubular body, ribs extending along a circumference of the tubular body, and at least one foam member disposed on the tubular body and between the ribs. The system also includes a conduit. The downhole tool is disposed in the conduit. A void is defined by the tubular body, the ribs, and the conduit, and the foam member is disposed in the void.

A shifting sleeve tieback seal system may include a body portion and a swellable material disposed about a circumference of the body portion. The swellable material is configured to expand in response to exposure to wellbore fluids. Further, the system may include an upper end ring disposed in a position axially above the swellable material, a lower end ring disposed in a position axially below the swellable material, and a sleeve disposed radially outward from the swellable material and sealed against the upper end ring and/or the lower end ring in a run-in position to isolate the swellable material from wellbore fluids. The sleeve is configured to contact a downhole feature in a setting position and contact with the downhole feature is configured to move the sleeve to expose the swellable material to wellbore fluids such that the swellable material expands to seal against a downhole tubular.

A liner hanger system for use in a subterranean well is disclosed. The liner hanger system comprises a well casing and a liner hanger. The liner hanger comprises a spike extending in an annular ring around an outer perimeter of the liner hanger. The spike comprises an annular groove defined therein. The liner hanger further comprises an annular seal positioned at least partially within the annular groove. The liner hanger is expandable to transition between an initial state where the spike is not in contact with the well casing and an expanded state where the spike is in contact with the well casing. The spike and the annular seal are configured to seal an uphole well portion from a downhole well portion when the liner hanger is in the expanded state.

Liner hanger system

Provided is a liner hanger, a method, and a well system. The liner hanger, in one aspect, includes a liner hanger body having an expansion section movable from a radially unexpanded state to a radially expanded state in contact with an inside diameter (ID) of a wellbore tubular. The liner hanger may further include a support assembly coupled to the liner hanger body, the support assembly including a support housing, and a mechanical support structure positioned radially inside of the support housing. In one aspect, the mechanical support structure is movable from a first position radially misaligned with the expansion section when the expansion section is in the radially unexpanded state to a second position at least partially radially aligned with the expansion section when the expansion section is in the radially expanded state. The liner hanger, in one aspect, further includes expandable metal coupled to the mechanical support structure.

A swellable metallic material is activated upon functional movement of a tubular member to lock the tubular member in place. In one example, a well tool includes a tubular member moveable within a through bore of a tool housing from a first position to a second position to perform a tool function. A swellable metallic material is captured in a cavity. The tubular member blocks flow to the cavity in the first position and opens the cavity for exposure of the swellable metallic material to an activation fluid in the second position. The swellable metallic material is configured to swell into engagement with the tubular member in response to the exposure to the activation fluid to hold the tubular member in the second position.

A well system may include a tubing string positioned downhole in a wellbore defining an annulus between the tubing string and a wellbore. An annular safety valve may be positioned at the surface of the wellbore for controlling a passage of gas through the annular safety valve into the annulus. The annular safety valve may include an inductive coupler that is coupled to a power source at the surface via a power line for powering the annular safety valve.

A wellbore completion system includes an expandable liner hanger with a post-setting fluid flow path. The system includes an expandable liner hanger that can be expanded by a running tool prior to a completion operation in a wellbore. The system also includes a circulating sleeve that can be manipulated by the running tool. The circulating sleeve can provide a return path for fluid internal to the expandable liner hanger for the completion operation that is performed subsequent to releasing the running tool from the expandable liner hanger.

Expandable liner hanger with post-setting fluid flow path

A variety of methods, systems, and apparatus are disclosed. In one example, a well tool is deployed downhole on a conveyance (e.g., tubing string) with the well tool in an open condition, wherein a flow path of the tool is in fluid communication with the tubing string. A swellable metallic material is arranged along the flow path. A service operation may be performed while the tool is in the open condition, including flowing a well fluid down the tubing string and through the flow path of the tool. After performing the service operation, an activation fluid may be delivered downhole to the well tool to activate the swellable metallic material to close the flow path of the tool.
