Born approximation 3D inversion for the marine CSEM data
Marine controlled-source electromagnetic (MCSEM) is a recently developed method for the offshore hydrocarbon detection. In this paper, we introduce the study of the 3D inversion for MCSEM data with the Born approximation method. The inversion speed is fairly improved by using reciprocal theory in the forward processing. The electrical character and geometric size of synthetic EM data inversion results show good agreement with the model. The methodology is also tested on the dataset of an MCSEM survey conducted in the Troll West Gas Province (TWGP), and the interpretation is satisfactory. Therefore, the Born approximation is an effective approach to improve the interpretation precision for the MCSEM data set.
