Coloardo Collocated Resources


The new database for Colorado includes 167 thermal wells and springs, a 33% increase over entries reported in 1980. A total of 382 geochemical analyses was compiled for these sites. Cappa and Hemborg (1995) identified 93 geothermal areas, each generally less than 8 km2 in size. The great majority of the geothermal areas occurs west of the Front Range within the Rocky Mountain Province. Recommended R&D activities include the compilation of oil and water-well data, geological and geophysical studies, thermal gradient drilling, water sampling and fluid geochemistry for six areas.
