4.4 Interpretations The data collected from this study are not strongly affected by convective fluid flow in the wellbores or surrounding strata. Rather, the geothermal gradient profiles show a more conductive thermal regime in the vicinity of the wells. Unfortunately, the wells are too shallow to make more significant observations of the deep thermal regime, but the high geothermal gradients in the Paliza Canyon and E10 wells show some promise of quantifying temperatures of a geothermal reservoir at ~900 m depth that may be explained using a transient model for the flow of warm water at depth.

4.4.1 Geothermal gradient profiles and their projected temperatures at depth The constant geothermal gradient from the JP Water Wells is slightly higher than the background gradient of the Earth (~30 °C/km; Turcotte and Schubert, 2002), but are average for the Rio Grande rift (Reiter et al., 1975). The constant gradient also shows fairly homogenous lithology with a slight decrease in thermal conductivity (K) with depth through the wellbore. According to thickness and temperature gradient data, the well was spudded in the Zia Formation and probably been completed in the same formation. Projected temperature of the JP Water Wells (Figure 4.5) is based on the average thermal gradient down to the estimated depth of the hydrothermal outflow plume aquifer in the Madera limestone at ~1254 m from the surface (base of the Madera, see Goff et al., 1988; Osburn et al., 2002; Kelley et…
