Abstract :
We have developed a new series of 3D forward modeling codes for various geoelectromagnetics (geoEM) applications, including: (1) induction logging in deviated wells, (2) grounded and airborne controlled-source EM, (3) magnetotellurics (MT), and (4) global induction studies. This series of codes has proven to be effective way to simulate geoEM fields in complex 3D environment. Among the main features of these codes are the ability to work on PC platforms, and the combination of a fast, but exact state-of-the-art integral equation approach.
