What is it about?
This paper details the process for building confidence in using these relatively new data through benchmarking of drilled or known cases using existing multi-client data. The Benchmark demonstrated that predictions can be made with a confidence of about 80%.

Why is it important?
Seismic data alone are prone to several false positives such as low-saturation gas and lithology changes - when combined with the CSEM resistivity measurement, more confident prediction of large hydrocarbon accumulations can be made. Additionally, CSEM data are more able to make a volume estimate of high saturation hydrocarbons thus increasing the ability to identify economic accumulations.
