3D Forward Simulation of Borehole-Surface Transient Electromagnetic Based on Unstructured Finite Element Method

Minerals
The time-domain electromagnetic method has been widely applied in mineral exploration, oil, and gas fields in recent years. However, its response characteristics remain unclear, and there is an urgent need to study the response characteristics of the borehole-surface transient electromagnetic(BSTEM) field.
