3D CSEM inversion is EMGS’s standard tool to reconstruct the subsurface resistivity distribution from the measured CSEM data. The goal of CSEM inversion is to reconstruct a resistivity model that explains the CSEM data and is geologically meaningful.

Our 3D CSEM inversion has been used successfully to image CSEM data acquired in a variety of geological settings such as shallow water, continental slope, deep water and salt basins for a range of E&P applications.

Since 2008 our inversion technology and workflows have undergone continuous development to improve accuracy and reliability as we continue to adapt to new acquisition approaches.
