Los Alamos National Laboratory (LANL) hot-hole logging technology for geothermal projects was retrofitted into cased-hole logging tools (gamma ray, neutron and casing collar) for use in deep gas wells. Lab tests indicated that hot-hole tools would last three times longer at 400 F (204 C) bottomhole conditions. During logging runs in Western Oklahoma, Beckham County deep gas wells, standard cased-hole logging tools failed in two to four hours, but hot-hole tools ran successfully for two consecutive six-hour logging runs (12 hours). Subsequent to this, retrofitted tools were equally effective in South Texas and Wyoming. This paper reviews results and design of this equipment.
