Abstract

Deep oil and gas as well as geothermal wells require logging with high temp resistant tools. They reaching their technical limits or are very expensive to build and/or operate. Proposed Solution: Wire Line Tools might be cooled with an circulation system from surface (one way or coaxial). Fluid will be circulated close, around or trough the wire line probe or will drive cooling systems (e.g. compressor based) while operating and/or run in and/or OOH. The wireline prob system might be isolated from the fluid system in the borehole to manage and/or to maintain casing and formation pressure integrity (density/pressure and chemistry/chemical interaction). The coaxial system might be made of insulating material such as low cost plastic or build as composite (e.g. steel coil with vacuum chambers, Zirconium Oxide coated components, etc.). Designed with reeled or jointed pipe. Low temp tubular or hose material might be self protected on its own, due a permanent system cooling while pumping cool fluid down hole. High temp or medium resistant sensors might be put closer to the formation (e.g. outside of the insulation chamber) to improve formation evaluation quality or make measurements possible. The coiling flow can be guided around the wireline probe or through.
