Abstract: 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.

Abstract: 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.

Abstract: A rotating ball valve may be employed in a liner hanger setting tool. A rotating ball member maintains contact with a valve seat throughout the operation of the rotating ball valve, thereby preventing debris from settling on the valve seat and compromising the integrity of a seal through a fluid flow path defined through the setting tool. The rotating ball valve may be actuated by selectively applying fluid pressure to the flow path, or by mechanical manipulation. Once the fluid flow path is closed, a latch may be activated to maintain the rotating ball valve in the closed configuration and a pressure may be applied against the closed rotating ball member. A downhole movement be induced by the applied pressure to drive an expansion cone through an expandable liner hanger, to secure a liner in the wellbore.

Abstract: 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.

Abstract: 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.

Abstract: A well unloading valve for a petrochemical well tubing comprising a flow passage connecting an annulus outside the tubing with the inside of the tubing; a lock-out sleeve for selectively closing the flow passage, wherein the lock-out sleeve can be moved from an open to a closed position by means of hydraulic pressure within the tubing; an electrically activated motor module for moving a seal, wherein the seal selectively opens a hydraulic connection from the inside of tubing to the lock-out sleeve for moving the lock-out sleeve hydraulically from the open to the closed position; and a check valve within the flow passage for allowing a flow from the annulus into the tubing and for blocking a flow from the tubing into the annulus. Further a method for unloading a petrochemical well tubing is claimed.

Abstract: 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.

Abstract: A liner for a wellbore having a sidewall in which one or more nozzles are formed is described, wherein the one or more nozzles are plugged by temporary plugs. Also described is a method of completing an open hole well that penetrates a subterranean formation in which a liner having a sidewall in which one or more nozzles are formed, wherein the one or more nozzles are plugged by temporary plugs, is deployed in the well such that the nozzles communicate with the formation.

Abstract: A system and method for summarizing video feeds correlated to identified speakers. A transcriber system includes multiple types of reasoning logic for identifying specific speakers contained in the video feed. Each type of reasoning logic is stored in memory and may be combined and configurable to provide an aggregated speaker identification result useful for full or summarized transcription before transmission across a network for display on a network-accessible device.

Abstract: Methods and system are provided for determining a topical influence value of the individual based on aggregated viral properties of tagged content citing the individual. A processor of a computer is used to match content within a web-site with a selected topic and to tag matching content to generate tagged content. Viral properties for the tagged content are extracted, and viral properties of the tagged content citing an individual in the tagged content are aggregated to form aggregated viral properties of the tagged content citing the individual. Based on the aggregated viral properties of the tagged content citing the individual, a topical influence value of the individual can be computed.
