A Discussion About Robust and Classical Magnetotelluric Processing Techniques: a Case Study on Santos Basin

In this work we made a statistical treatment of marine magnetotelluric data collected on Santos basin in southeast cost of Brazil. The basin is part of the group of basins of Brazilian pre-salt province. We analyzed the data and performed classical and robust processing as an attempt to avoid effective noise that is critical in many stations of the survey. The suitable processing scheme and correct noise removal are key points of magnetotelluric workflow and can definitively help to improve the data quality at local sites and this way reach better results. Finally, we hope to accomplish a joint inversion using these magnetotelluric data and additional seismic and magnetic data.
