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: 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 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.

Abstract: Apparatus and methods for penetrating a downhole target within a wellbore include providing a body with a longitudinal axis, a first end, and a second end into a wellbore, the body having a nozzle at the first end. The nozzle is adapted to project a medium in a direction generally parallel to the longitudinal axis to affect a downhole target. An actuator in communication with the medium is usable to initiate the apparatus. The nozzle can be provided with a geometry configured for projecting the medium in a pattern that separates the downhole target into at least two portions. The medium can include a ferromagnetic material that becomes associated with the downhole target to facilitate recovery of the target or portions thereof using a retrieval device having a magnetic element.

Abstract: Systems and methods usable in conduit cutting operations are disclosed. Specifically, an anchor assembly is configured to be attached to a cutting apparatus and to equalize the upward and downward forces on the cutting apparatus during performance of the cutting operation. In addition, the anchor assembly is configured to impart a rotational motion in the cutting apparatus to produce a clean and complete horizontal cut of the conduit at a desired location.
