Isotopic and thermodynamic reservoir characteristics of the Copahue-Caviahue geothermal field, Neuquén province Argentina

Mostrar todas las versiones(2)

The geothermal field of Copahue-Caviahue, situated in the neighboring of an active volcano, has been defined as a vapor dominated field, with stratified layers, connected by fractures, with good vertical permeability within the reservoir. 2H and 18O analyses done on vapor, water, associated gas anal...
