Abstract
Electromagnetic (EM) methods have been widely used in geothermal exploration. EM passive methods such as Magnetotellurics (MT) and Audio Magnetotellurics (AMT) have been the industry standard due to the existing 3D interpretation tools. Passive methods encounter a few problems, including variations in signal strength, azimuth, static shift, and others stemming from cultural noise. A new high-power controlled-source electromagnetics (CSEM) array system offers a solution to these issues. By combining passive MT/AMT, CSEM measurements, and Cloud-enabled EM data acquisition and quality control, the EM array system provides a better solution in areas of high cultural noise and real-time quality checks of field data. We clearly see this in the field data examples. As we enter the energy transition, geothermal production with CO2 injection or cooling and re-injection of the produced fluid are of great interest for development and investment. By acquiring passive MT/AMT and CSEM, we obtain complementary measurements from both applications for exploration and monitoring.
