Application of EM Method to Study the Distribution of Geological Layers in Thermal Storage and CCS

In recent years, the application of EM methods in conjunction with geological target identification and application has received considerable attention in fields such as geothermal development and CO2 storage facility construction. This article focuses on the effectiveness of time-frequency electromagnetic method (TFEM) in dynamically tracking changes in thermal reservoir distribution, as well as the application of transient electromagnetic method (TEM) in identifying target rock masses in CO2 storage facilities.
