    摘要: Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with a deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Alternatively, the deployment of the compacted or compressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid.

    摘要: An apparatus includes a housing configured to be disposed in a borehole in a resource bearing formation, the housing including an axially extending fluid conduit configured to receive borehole fluid, and a seating assembly including a convertible component that is configured to be actuated to move the convertible component in a radial direction between an open position and a seating position. The convertible component extends radially into the fluid conduit and forms a landing seat for an object when in the seating position, and the convertible component allows passage of the object therethrough when in the open position.

    摘要: An apparatus for determining a location of a downhole component includes at least one transmitter device and a receiver device. One of the at least one transmitter device and the receiver device is disposed at a first component of a borehole string configured to be deployed in a borehole and retained at a stationary position, and another of the at least one transmitter device and the receiver device is disposed at a moveable component configured to be moved while the first component is at the stationary position, the at least one transmitter device configured to emit a wireless signal and the receiver device configured to detect the wireless signal when the first component is at the stationary position. The apparatus also includes a processing device configured to receive signal data and estimate a location of the moveable component relative to the first component based on the signal data.
