Abstract: A downhole torch system and method of use includes a cylindrical housing, a protective material provided on at least one of the cylindrical housing and the fuel load, and a fuel load located within the cylindrical housing. The protective material is provided between the fuel load and the cylindrical housing to protect the cylindrical housing from adverse effects caused by the reaction of the burning fuel and/or the subsequent production of combustion products for cutting and/or perforating processes during operation of the torch system. The protective material significantly improves the cutting and/or perforating performance of the torch system.

Abstract: A degradable plug device for a pipe prevents fluid flow through the pipe until the plug device has been removed from the pipe. The plug device includes a body which is at least partially of a degradable material. The exposed surfaces of the degradable plug include a protective layer thereon. The body includes a chamber therein. The body is disposable in the pipe to prevent fluid flow through the pipe. The plug is adapted to undergo a degradation initiation operation such that well fluid is able to enter the chamber to initiate corrosion or dissolution of the body from inside the chamber. The plug is useful for temporarily blocking a pipe within a well to control the flow of fluids or to actuate tools within the well.

Abstract: A location connector connects a first tubular to a second tubular, and includes a cylindrical main body extending in a longitudinal direction. An outer surface extends around a circumference of the main body, and an inner surface faces 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.

Abstract: 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.

Abstract: A degradable plug device for a pipe has an outer plug body and an inner plug for preventing fluid flow through the pipe until the inner plug has been removed from the outer plug body. The outer plug body and the inner plug are of a degradable material. The inner plug has a chamber with at least one port to the exterior of the inner plug. The exposed surfaces of the degradable plug have a protective layer thereon. The inner plug is disposable in at least a first position, in which the inner plug prevents the fluid flow through the pipe. The inner plug is adapted to undergo, in use, a degradation initiation operation such that fluid is able to enter the chamber via the at least one port to initiate corrosion or dissolution of the inner plug from inside the chamber.

Abstract: A setting tool having a tool body, a chamber configured to contain a non-explosive fuel configured to generate gas and plasma, a cavity, a bleed sub located between the chamber and the cavity. The bleed sub is configured to bleed pressure from the chamber to the cavity after the non-explosive fuel has been initiated. The setting tool also includes a piston disposed within the cavity oriented to stroke in a first direction after the non-explosive fuel has been initiated. The piston may divide the cavity into an upper volume that may receive the pressure increase from the bleed sub and a lower volume. The setting tool may also include a shaft mechanically connected to the piston within the lower volume of the cavity. The shaft may include a dampening conduit configured to drain a fluid from the lower volume after the non-explosive fuel has been initiated.

Abstract: 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.

The electrical connector is configured to break when the reciprocating hammer is released from the first position.

Abstract: An anchoring tool for positioning a downhole tool within a wellbore conduit is described herein. The anchor tool uses replaceable blades having protrusions that are configured to align with corresponding grooves in an anchor sub receptacle that is located at a known position along the wellbore conduit. The blades of the anchor tool are configured to move radially relative to the anchor tool body until the anchor tool is aligned with a compatible anchor sub. When the anchor tool and the compatible anchor sub are aligned, the protrusions of the anchor tool blade extend into the grooves of the anchor sub receptacle and a locking mechanism within the anchor tool inhibits further radial movement of the blades. A downhole tool connected to the anchor tool can therefore be positioned at a precise location relative to the known location of an anchor sub receptacle.

Abstract: 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.
