Geophone emplacement holes PC-1 and PC-2 were drilled at Fenton Hill by Maness Drilling Company of Farmington, NM for Los Alamos National Laboratory in 1984. These wells were drilled to facilitate microseismic monitoring of ongoing MHF experiments attempting to produce a viable geothermal reservoir.
PC-1 was completed to a final depth of 663.9 m in March, 1984, and encountered maximum temperatures of 84°C. PC-2 was drilled to a total depth of 558 m in August 1984 following MHF experiment 2042, and encountered maximum temperatures of 54°C. Lithology and temperature logs from these wells are discussed in Shevenell et al. (1988). A report published in 1988 integrated stratigraphic, temperature gradient, hydrogeochemical, hydrologic, and geologic data from these and other wells in order to construct a comprehensive hydrologic and temperature gradient model of the hydrothermal outflow plume issuing from the western margin of the Valles caldera (Goff et al., 1988).
