WebThe geothermal reservoir's hot in-situ fluid (or geofluid) is produced to the surface via a wellbore, if necessary assisted by a pump. On the surface, the hot geofluid transfers some of its heat to the secondary cycle, via a heat exchanger, thus cooling in the process. WebConsequently, the magnetotelluric (MT) method has become the preferred method for exploration of deep geothermal resources. The MT method is sensitive to the electrical resistivity signatures of the main components of the geothermal system (heat source, cap rock layer, and structures that conduct fluid flow). little brown bat weight
