Abstract
A cable structure for use in a wellbore formed in a subsurface formation. The cable structure comprises superconducting material configured to provide power to a downhole tool in the wellbore. The cable structure comprises a cryogenic liquid supply channel configured to supply fluid to reduce temperature of the superconducting material. The cable structure comprises one or more cryogenic liquid return channels.
Claims18
A cable structure for use in a wellbore formed in a subsurface formation, the cable structure comprising:
- superconducting material configured to provide power to a downhole tool in the wellbore;
- a cryogenic liquid supply channel configured to supply fluid to reduce temperature of the superconducting material, wherein the cryogenic liquid supply channel includes two or more chambers;
- and
- one or more cryogenic liquid return channels.
1 more element
A system comprising:
- a downhole tool positioned in a wellbore formed in a subsurface formation;
- superconducting material configured to provide power to the downhole tool in the wellbore;
- a cryogenic liquid supply channel configured to supply fluid to reduce temperature of the superconducting material, wherein the cryogenic liquid supply channel includes two or more chambers;
- and
- one or more cryogenic liquid return channels.
2 more elements
A method comprising:
- supplying a fluid to a cryogenic liquid supply channel comprising two or more channels and positioned within a cable structure to reduce a temperature of superconducting material, wherein the cable structure is configured to supply power to a downhole tool in a wellbore formed in a subsurface formation via the superconducting material;
- and
- returning the fluid to surface via one or more cryogenic liquid return channels.
