Abstract
An apparatus comprises one or more high temperature superconducting cables configured to supply power from surface to a bottom hole assembly positioned in a wellbore while drilling the wellbore in a subsurface formation. The apparatus comprises one or more cryogenic liquid supply channels positioned within the one or more high temperature superconducting cables, wherein fluid is pumped, via one or more cryogenic pumps, into the one or more cryogenic liquid supply channels to keep a temperature of the one or more high temperature superconducting cables below a critical temperature.
