| Abstract | Interpretation of magnetotelluric data from the Berlin geothermal prospect, El Salvador, by standard techniques such as apparent resistivity and Bostick resistivity contouring at selected elevations and on profiles failed to delineate the deep geothermal reservoir structure because of small resistivity contrasts obscured by static shift effects and boundary influences However, one-dimensional modelling using finite layers, together with data management tools to select and compare parameters of layers of interest, has resulted in a very clear picture of the depth and extent of the geothermal reservoir, and has tentatively located the upflow and outflow paths and areas of enhanced porosity. |
