There are many ways to imagine the geothermal reservoir. This includes the Drilling, Stress Analysis, Geological Mapping, Geochemistry Investigation, Magnetotelluric Survey, Dense Seismic Array, and Airborne LIDAR/Gravity/Magnetics. However, the most important issue which are concerned by the geothermal investors are: What is the resolution? When the result may be reliable? Which the case will be applied? Where the example can be found? And how effective is the method? In this session, we will examine various methods modelers use to identify and image geothermal reservoirs.
