摘要： A releasable connector apparatus has a connector mandrel to be coupled to a conveyance and a housing to be coupled with a downhole tool. A socket is defined within the housing for receiving the mandrel. A latch arrangement operable within the socket has a latch member and is moveable relative to the housing between a connect position (in which the latch is locked relative to the mandrel to prevent removal of the mandrel from the socket), and a disconnect position (in which the latch is unlocked relative to the mandrel to permit removal of the mandrel from the socket). A cavity defined within the housing is sealingly isolated from the socket. An actuator mounted within the cavity is coupled to the latch arrangement to move relative to the housing between a first position (in which the arrangement is in its connect position), and a second position (in which the arrangement is in its disconnect position).

摘要： A method of downhole operations with a wireline deployed tool that has become stuck downhole. The wireline is selectively detached from the stuck tool, and a tubular is attached to a coupling provided with the tool. The tool is unstuck by applying upward and downward forces to the tool with the tubular. The coupling further provides communication between a line in the tubular and the downhole tool, thereby providing communication between the tool and surface. Thus, after unsticking the tool, wellbore operations can continue with the tool attached onto the tubular.

摘要： A first wireline tool embodiment includes a segmented tool body having a joint deployed between each adjacent pair of tool body sections. The joint may be configured to extend axially (causing a relative axial displacement of the adjacent tool body sections) when the wireline tool is subject to an axial load. The joint may include, for example, a compliant joint or a protractible joint. The joint may be further configured to cause a relative rotation between the adjacent tool body sections when the wireline tool is subject to axial load. A second wireline tool embodiment includes a plurality of standoff rings deployed about an outer surface of a rigid tool body. The standoff rings engage helical grooves in the outer surface of the tool body such that axial displacement of the tool body causes the standoff rings to rotate.

摘要： A method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe stuck in the well, and penetrating and/or heating a sidewall of the pipe portion with a beam of light. A system for freeing a pipe stuck in a subterranean well can include a tool deployed into a portion of the pipe stuck in the well by a differential pressure from a wellbore to a formation penetrated by the wellbore. A beam of light emitted from the tool penetrates the pipe portion. Another method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe which is biased against a wall of a wellbore by differential pressure, and directing a beam of light to the pipe portion.

摘要： A downhole disconnect device for disconnecting an intervention tool string from a wireline, includes: a tubular body having a first part directly or indirectly coupleable to the wireline and a second part connectable directly or indirectly to an intervention tool string; an actuator for disconnecting the second part of the tubular body from the first part of the tubular body; at least one sensor to detect when the tool string is stuck in use and to produce an output signal accordingly; a controller configured to receive the output signal and selectively operate the actuator accordingly; and a power source. The tubular body is adapted to house the actuator, sensor, controller and power source and the device further comprises a timer configured to delay operation of the actuator by a predetermined time on receipt of the output signal from the sensor. There is also a method of operating the downhole disconnect device.
