Geophysical Conceptual Model of San Vicente Geothermal Area, El Salvador

摘要

With the purpose of evaluating the thermal potential of theSan Vicente geothermal area, the Geophysics Area of Studies Management carried out from February to April, 2005, geophysical prospecting studies of Standard Gravity, Magnetic and Magneto Telluric (MT) combined with Electromagnetic Method in the Time Domain (TDEM). The study area for Gravity was 250 Km~(2), for MT-TDEM 80 Km~(2), and 40 Km~(2) for Magnetic. The concession area is 100 Km~(2). As a result, a geophysical conceptual model was created. The interpreted geophysical reservoir is distinguished by a high resistive basement and a positive gravity anomaly with an estimated area of 12 to 14 Km~(2) and 800 to 1000m of thickness. The seal cap is associated with a very conductive layer with resistivity values less than 10 ohm-m.
