摘要： Methods and systems for use in targeted removal of metals from a substrate via electrorefining are described. A self-propagating reaction is initiated by use of a thermite to reach high temperatures sufficient to induce localized melting of a salt situated on a metal or alloy substrate. Using a power supply connected to an electrode assembly, an electrorefining reaction capable of generating significant localized corrosion of the substrate is produced.

摘要： 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.

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 mixture and method of creating the mixture includes mixing hexachloroethane, stannous oxide, and aluminum together. The mixture may be loaded into at least one canister. The mixture may be combusted to create a smoke screen. The loading of the mixture into the at least one canister may include pressurized loading at loading pressures in the range of approximately 2300 psi to 3600 psi. The hexachloroethane may include approximately 30-40 parts by weight of the mixture and have a particle size of approximately less than 850 μm. The stannous oxide may include approximately 55-65 parts by weight of the mixture and have a particle size of approximately less than 150 μm. The aluminum may include approximately 5-10 parts by weight of the mixture and have a particle size of approximately less than 45 μm. The mixture is devoid of zinc chloride.
