oa Marine CSEM for the future.

Looking back from the very first test of using CSEM to detect hydrocarbon reservoirs in 2001, we have seen a tremendous improvement in technology and processing. We have moved from 2D lines to true 3D acquisition and from attribute analysis to 3D inversion. We have seen significant improvements in data quality and acquisition efficiency, and we have seen an increased effort in integrating EM data with seismic data. All these improvements have contributed to better resolution, deeper penetration, less ambiguity, and, as a consequence, better interpretation and understanding of the subsurface.
