Geological modelling from field data and geological knowledge

Abstract: The analysis of multiple data sets is required to select a realistic 3D geological model among an infinite number of possibilities. An inverse method that aims at describing the 3D geometry of geological objects is presented. The method takes into account the geology and the physical properties of rocks, while respecting the topological properties of an a priori model. The a priori model is built from the geological data-set and its geometry is largely dependent upon assumptions about inaccessible geology at d… Show more

“…The corresponding data misfit maps show a linear correlation coefficient of 0.999 (see details in Appendix A). This similarity illustrates that, as in many other studies, most changes related to holistic data integration in geophysical inversion occur primarily in model space, hence reducing the effect of non-uniqueness (Abtahi et al, 2016;Abubakar et al, 2012;Brown et al, 2012;Demirel and Candansayar, 2017;Gallardo et al, 2012;Gallardo and Meju, 2004, 2011Gao et al, 2012;Giraud et al, 2017;Guo et al, 2017;Heincke et al, 2017;Jardani et al, 2013;Juhojuntti and Kamm, 2015;Kalscheuer et al, 2015;Molodtsov et al, 2013;Moorkamp et al, 2013;Rittgers et al, 2016;Li, 2016, 2017).…”

“…The integration methodology we develop is similar in philosophy to the work of Brown et al (2012), Guo et al (2017) and Wiik et al (2015), who extract continuous structural information from seismic data to adjust the strength of the regularization term locally in order to promote specific structural features during electromagnetic inversion. However, our work differs from these authors in four main respects.…”
