Abstract
(English)
A 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 80-100C. The area investigated seems capable of producing high-enthalpy geothermal fluid; a deep reservoir is inferred, composed of a medium salinity (5000 ppm) and neutral brine, with computed temperatures between 250 and 300C, and with a high CO2 partial pressure. A second shallower reservoir is shown to be liquid-dominated, while water and steam occupy the shallow one the piezometic level (elevation 150 m) regulates the areal distribution of water spring and fumaroles. A partial self-sealing (mineral alteration) along outflows allows accumulation of hot fluids, while recharge is from local meteoric water
