Paper Number: SEG-2018-2965257
.... Current EMI systems can be easily coupled with high-precision positioning systems, and by using Transmitter-Receiver (Tx-Rx) separations ranging from 0.3 m up to 4 m, multiple apparent electrical conductivity values can be measured for different but overlapping soil volumes. The measured data can be used...

..., and more efficiently using resources (Singhai and Card, 1988). Because the electrical conductivity of a lithologic unit is af- fected by steaming, electric and electromagnetic methods are promising tools to detect and image SAGD steam chambers. Additionally, these types of surveys can be much more cost...

... are well suited to submersible-based surveys. Since electrical conductivity of subseafloor materials can be frequency dependent, these induced polarization (IP) effects may affect the reliability of TDEM data interpretation. In this paper, we investigate IP effects on TDEM responses of deep-sea...

...). An electrically conductive proppant could create a significant physical property contrast between the propped region of the reservoir and the host rock. Electromagnetic geophysical methods can be used to image this property (Heagy and Oldenburg, 2013). However, traditional geophysical inversions are poorly...
