摘要： Apparatus, systems, and methods are used for activating a downhole tool, powered by an exothermic reaction, for operation, while deploying a tubing string from a wellbore surface. The tubing string comprises a coupling for enabling pressurized activation of the downhole tool, which comprises a fuel (e.g., thermite) for producing the exothermic reaction. The coupling enables fluid to flow into an interior of the coupling through a first flow passage, during descent of the downhole tool. A stopper is dropped and/or seated to cause the coupling interior to pressurize to an activation pressure, which causes an activator to activate a burn within the downhole tool. Once the downhole tool completes its operation, the coupling interior is further pressurized to burst a burst disc, which opens a second flow passage for fluid to flow from the interior to exterior of the coupling, while downhole tool and coupling are raised to the surface.

摘要： A jarring tool includes a main body having a central bore extending therein, an upper connection at a proximal end of the main body for attaching the jarring tool to wireline or slickline, a lower portion at a distal end of main body, and a reciprocating hammer fixed at a first position within the central bore of the main body. The jarring tool further includes a central aperture extending along a length of the reciprocating hammer, an electrical connector extending from the upper connection and through the central aperture of the reciprocating hammer to at least the lower portion of the main body, and a release mechanism on the main body for releasing the reciprocating hammer from the first position and allowing reciprocating movement of the reciprocating hammer along the central bore. The electrical connector is configured to break when the reciprocating hammer is released from the first position.

摘要： A location connector connects a first tubular to a second tubular, and includes a cylindrical main body extending at a longitudinal direction. An outer surface extends around a circumference of the main body, and an inner surface laces the central bore of the main body. A first connector, on a first end of the main body, is configured to attach to the first tubular. A second connector, on an opposite second end of the main body, is configured to attach to the second tubular. A female profile is provided on the inner surface. and includes a plurality of grooves for selective engagement with a discrete complementary profile comprising one or more protruding members of a downhole tool. Each of the grooves comprises a no-go shoulder that prevents movement of the tool in one direction, and each of the grooves permits clocking movement of the tool in an azimuthal direction.

摘要： Systems and methods include an extreme range anchor, having extending assemblies configured to engage a wellbore, for providing a self-centering, reusable anchor location within a wellbore. The extending assemblies include a first set of arms connected to a first brace, a second set of arms connected to a second brace, and a set of footplates. Each footplate in the set of footplates is connected to the first set of arms and the second set of arms. Each footplate includes a fixator coupled to a radially external face and configured to securely engage the wellbore. The system also includes a pull rod rigidly coupled to the first brace and slidably connected to the second brace. Forcing the pull rod in an axial direction shortens a distance between the first brace and the second brace and forces the set of footplates to move in a radial direction toward the wellbore.

摘要： Systems and methods for removing casing from a wellbore including a casing removal tool that includes a tubular body configured to contain a thermite fuel mixture configured to initiate into a molten thermite fuel. The casing removal tool also includes a nozzle array having a plurality of nozzles positioned on an external surface of the tubular body. The nozzle array is configured to impinge the molten thermite fuel from within the tubular onto the wellbore casing. The casing removal tool also includes an orientation lug configured to anchor into a downhole orientation tool.

摘要： A system and method for positioning a tool within a wellbore, wherein the interior surface of a positioning apparatus includes one or more pluralities of grooves, each defining a selected profile. A tool is lowered into the positioning apparatus, having a blade in communication therewith. The blade includes a plurality of protruding members, which define a profile complementary to at least one of the selected profiles formed by one of the pluralities of positioning apparatus grooves. A biasing member in communication with the blade can continually bias the blade toward the interior surface of the positioning apparatus to cause the profile of the blade to engage within the corresponding complementary profile of the positioning apparatus. Positioning a tool in this manner is advantageous for locating cutting tools at a precise location to sever a joint, perforate casing or stack multiple tool operations at a fixed, targeted point within a wellbore.
