National Geothermal Database System – Colorado DatabasesCompleted Databases:

Thermal springs & wells, water chemistry, geothermometry; geothermal bibliography; heat flow & geothermal gradient maps; bottom-hole-temperatures (BHTs), corrected BHTs & BHT geothermal gradients; draft BHT gradient maps of individual sedimentary basins; active fault data.

Databases In Progress:Temperature-depth logs; thermal conductivity data;

radiogenic heat production data; co-produced fluids; earthquakes.
