Abstract
A geothermal wellbore tractor is provided. The geothermal wellbore tractor can include a hydraulic subsystem, a plurality of wheels in communication with the hydraulic subsystem, and a slick line attachment mechanism in communication with the hydraulic subsystem and engaged to a slick line. Motion of the slick line can be operable to generate power for the hydraulic subsystem. The hydraulic subsystem can be operable to control motion of the plurality of wheels.
Claims20
A geothermal wellbore tractor comprising:
- a hydraulic subsystem;
- a plurality of wheels in communication with the hydraulic subsystem;
- a slick line attachment mechanism in communication with the hydraulic subsystem and engaged to a slick line;
- a chemical steam subsystem in communication with the hydraulic subsystem and operable to generate power for the hydraulic subsystem, the chemical steam subsystem comprising:
- a first chamber operable to contain a first compound;
- a second chamber surrounding the first chamber, the second chamber operable to contain a second compound;
- and
- a steam engine,
- wherein motion of the slick line is operable to generate power for the hydraulic subsystem, and
- wherein the hydraulic subsystem is operable to control motion of the plurality of wheels.
(canceled)
A geothermal wellbore system comprising:
- a slick line;
- a geothermal wellbore tractor comprising:
- a hydraulic subsystem;
- a plurality of wheels in communication with the hydraulic subsystem;
- an anchor;
- a slick line attachment mechanism in communication with the hydraulic subsystem and engaged to the slick line;
- a chemical steam subsystem in communication with the hydraulic subsystem and operable to generate power for the hydraulic subsystem, the chemical steam subsystem comprising:
- a first chamber operable to contain a first compound;
- a second chamber surrounding the first chamber, the second chamber operable to contain a second compound;
- and
- a steam engine;
- and
- a slick line truck operable to control motion of the slick line,
- wherein motion of the slick line is operable to generate power for the hydraulic subsystem, and

A geothermal wellbore tool power source comprising:
- a hydraulic subsystem;
- and
- a chemical steam subsystem in communication with the hydraulic subsystem and operable to provide power to the hydraulic subsystem, the chemical steam subsystem comprising:
- a first chamber operable to contain a first compound;
- a second chamber surrounding the first chamber and operable to contain a second compound;
- and
- a steam engine,
- wherein the first compound exothermically reacts with the second compound to produce high pressure steam, and
- wherein the steam engine converts the high pressure steam to hydraulic power for the hydraulic subsystem.
