Dr. Igor Buddo has more than 15 years of experience in electromagnetic survey for HC exploration with TEM and EM-IP techniques. The author has significant experience in onshore EM field works (more than 40 projects in Russia and abroad), data processing, and interpretation. The author is a key specialist for electromagnetic methods in the Institute of the Earth’s Crust, Siberian Branch of the Russian Academy of Sciences and OOO SIGMA-GEO. He is the developer of the approach to TEM interpretation in terms of thin-layered geoelectrical models for reservoirs exploration, joint interpretation of EM and seismic data. He is an Associate Professor of the Department of Applied Geology, Geophysics and Geoinformation Systems, Irkutsk National Research Technical University (IRNITu). The scientific interests lie in joint EM and seismic interpretation, TEM for near surface investigations, TEM for HC exploration and drilling settings (fluid loss and overpressure intervals) prediction. He is the author of more than 100 scientific papers. He is an active member of the Society of Petroleum Engineers (SPE), EAGE (European Association of Geoscientists and Engineers).
