Journal Article: The Geothermal Area Of El Pilar-Casanay, State Of Sucre, Venezuela, Geochemical Exploration And Model
AbstractA geochemical survey was carried out in the El Pilar-Casanay area, State of Sucre, Venezuela, in order to ascertain its geothermoelectric potential. The area is characterized by many natural manifestations with temperatures in the range 80-100°C. The area investigated seems capable of producing high-enthalpy geothermal fluids; a deep reservoir is inferred, composed of a medium salinity (<5000 ppm) and neutral brine, with computed temperatures between 250 and 300°C, and with a high CO2 partial pressure. A second shallower reservoir is assumed to exist, with a temperature of the order of 200-220°C. The deep reservoir is shown to be liquid-dominated, while water and steam occupy the shallow one. The piezometric level (elevation 150 m) regulates the areal distribution of water springs and fumaroles. A partial self-sealing (mineral alteration) along outflows allows accumulation of hot fluids, while recharge is from local meteoric water.
