A marine Controlled-Source Electromagnetic (CSEM) survey is a useful tool for characterizing offshore hydrocarbon deposits because of its sensitivity to formation resistivity. Due to the geometry of most subsurface targets, 3D surveys tend to be pref

An example of 2D interpretation of marine CSEM survey data is presented.Following the conclusion of initial 1D modelling of the response measured in line with the source dipole, it is shown that assuming vertical anisotropy of the 2D earth model impr

The marine CSEM method is currently being applied to the problem of detecting and characterizing hydrocarbons in a variety of settings for exploration purposes. Because of its physics it can on one hand, distinguish between fluids within formations.
