Abstract
An apparatus for and a method of generating electrical power downhole using a quantum thermoelectric generator and operating a downhole device using the generated power.
Claims26
A system for use in a borehole, the system comprising:
- (a) a thermoelectric generator that produces electrical power in response to a difference of temperature between a first side of the generator and a second side of the generator and
- (b) a downhole device operated by the electrical power.
The system of claim 9 wherein the second side of the thermoelectric generator is in thermal contact with a fluid in the borehole.
A method of performing operations in a borehole, the method comprising:
- (a) producing electrical power by positioning a thermoelectric generator where there is a difference of temperature between a first side of the thermoelectric generator and a second side of the thermoelectric generator, and
- (b) operating a downhole device using the electrical power.
