| Status and Prospects of Electromagnetic Method Used in Geothermal Resources Exploration |
| As a clean, sustainable, and renewable energy resource, geothermal energy has attracted considerable attention worldwide. A strong correlation exists between resistivity and geothermal-related parameters, including porosity, permeability, salinity, alteration and temperature. Electromagnetic methods have been widely used in geothermal exploration to effectively determine subsurface electrical structures, and are characterized by a wide detection range, high accuracy, low cost, and can reach large depths. This study mainly discusses the application and development of electromagnetic exploration in geothermal resources, geothermal electromagnetic tomography, and the electrical characteristics of geothermal elements. The applicability, effectiveness, and accuracy of electromagnetic methods in geothermal exploration are summarized based on examples of electromagnetic exploration in geothermal areas. Finally, the prospects of frontier methods and technologies in geothermal exploration and exploitation such as hybrid source ultra-wide electromagnetic data acquisition, high-precision inversion imaging, and major geothermal attributes identification are described. |
