Abstract
Subterranean oilfield high-temperature devices configured or designed to operate at elevated temperatures downhole in a well traversing a formation. A tool conveyance is configured for deployment in the well with a downhole cartridge comprising high-temperature sensitive components. A downhole cooling system includes a cooling fluid conduit having a first end configured for fluid connection with a source of cooling fluid and a second end configured for discharging cooling fluid in the well at at least an upper portion of a subterranean high-temperature zone such that cooling fluid circulates in the high-temperature zone.
