Abstract
Diffusive-to-Propagative Mapping (DPM) transforms a diffusive electrom agnetic field into a dual wave field to produce electromagnetic reflec tivity images similar to non-migrated seismic sections. An application of DPM to the COPROD2 data set gives reflectivity images showing thre e distinct reflectors attributed to resistivity jumps located at depth s ranging from 2 to 50 km. The deeper reflector may be related to a ma jor west-dipping seismic reflector detected with the COCORP seismic da ta.
