The simultaneous joint inversion of different geophysical datasets has proved to be a technique which results in better imaging in geologically complex areas like sub-salt and sub-basalt. Different approaches of joint inversion have been presented during recent years. We chose a structure based cross gradient approach (e.g. Gallardo and Meju, 2004) for the joint inversion of seismic and non-seismic methods, including gravity, magnetics and CSEM. The resulting models are consistent with all data sets, with each other and with structural and specific a priori information. We present our multi-parameter approach and examples of the application of the joint inversion method to synthetic data sets based on sections of the SEG salt and the Mre Margin.
