摘要： A severing apparatus is used for severing a conduit. The apparatus includes a main body section having an upper portion, a lower portion, and an intermediate portion. A combustible charge is located in the intermediate portion, and an ignition mechanism is coupled to the upper portion for igniting the combustible charge. A nozzle head is located in the lower portion and includes an internal cavity and a nozzle portion having apertures at spaced apart positions for providing passages from the internal cavity to outside of the nozzle head. The ignition mechanism is configured to ignite the combustible charge to create a flame and combustion products and pressure in the internal cavity for moving the nozzle head relative to the lower portion so that the nozzle portion protrudes out of the lower portion for passage of the flame and hot combustion products out of the apertures to sever the conduit.

摘要： An apparatus for providing pressurized fluid to a formation that includes a power source body configured to contain a gas-generating fuel and a tool body comprising a first chamber and a second chamber. The first chamber is configured to hold a fluid, and the second chamber is configured to receive gas from the gas-generating fuel within the power source body. The apparatus further comprises a piston sealed between the first chamber and the second chamber and configured to stroke through the first chamber in response to a pressure increase within the second chamber, and a hose configured to generate a high-pressure jet of the fluid and to extend from the tool body or a diverter sub into the formation when the piston strokes through the first chamber.

摘要： Apparatus, systems, and methods, for perforating a downhole object while minimizing collateral damage to other objects, include use of a perforating device having a body, at least one fuel source having a characteristic that produces a selected mass flow rate, a selected burn rate, or combinations thereof, and an initiator for reacting the fuel to project a force through at least one port in the body. Characteristics of the at least one fuel source can include use of differing fuel types, shapes, and placement to achieve the desired mass flow rate or burn rate, and thus, a controlled force from the apparatus. An anchor or similar orienting device can be used to control the direction and position from which the force exits the apparatus. Openings formed in downhole objects can include a chamfered profile for facilitating future orientation or for injecting or removing substances from a formation.

摘要： A system and method for positioning a tool within a wellbore are described herein. The interior surface of a tubular string is provided with one or more pluralities of grooves, each defining a selected profile. A tool is lowered into the tubular string, having a blade in communication therewith. The blade includes a plurality of protruding members thereon, which define a profile complementary to at least one of the selected profiles formed by one of the pluralities of grooves. A biasing member in communication with the blade continually biases the blade toward the interior surface of the tubular string to cause the profile of the blade to engage within the corresponding complementary profile of the tubular string. Positioning a tool in this manner is especially advantageous for locating a cutting tool at a precise location to sever a tubular segment at a joint, releasing tensile forces from the joint.

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： A setting tool for deploying a downhole tool within a wellbore is described herein. The setting tool uses an in situ non-explosive gas-generating power source to generate high- pressure gas, which drives a mechanical linkage to actuate the deployment of the downhole tool. According to certain embodiments the non-explosive gas-generating setting tool contains no hydraulic stages and may contain only a single piston. The setting tool may be fitted to provide different stroke lengths and can provide usable power over a greater percentage of its stroke length, compared to setting tools using explosive/pyrotechnic power sources. Methods of using a non-explosive gas -generating setting tool to deploy a downhole tool within a wellbore are also disclosed.

摘要： A tubular perforating apparatus includes a nozzle section comprising a nozzle head located therein and adjacent a combustible fuel material. The nozzle head includes an internal cavity and a nozzle portion including an opening on one side of the nozzle portion that directs the cutting fluids out the internal cavity in a first radial direction to produce a reaction force on the apparatus in an opposite second radial direction. The reaction force moves the apparatus in the second radial direction to be against an inner wall of the tubular and temporarily anchors the apparatus against the inner wall. The nozzle head is movable via the pressure and the cutting fluids from a closed position within the nozzle section to an open position in which the nozzle portion protrudes out of the nozzle section so that the opening is exposed to the tubular for directing the cutting fluids onto the tubular.

摘要： Apparatus, systems, and methods are used for activating a downhole tool, powered by an exothermic reaction, tor 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 born 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.
