Abstract

This paper describes a method to invert marine CSEM data from anisotropic layered media. The method minimizes the relative difference between estimated and observed data. It applies the "Total Variation" method's L1 norm equality constraints to parameters in adjacent layers, which allows for sharper variations than the more traditional smoothness constraints using the L2 norm. To cope with the added difficulty of resolving anisotropic layers, our method also imposes equality constraints between the different components of the conductivity tensor in each layer. The results show that these steps are able to improve the detection of the resistive target usually sought in the inversion of marine CSEM.
