  • Patent number: 11591872
    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.

  • Patent number: 10900309
    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.
