Geophysical modeling via simultaneous joint inversion of seismic, gravity, and electromagnetic data: Application to prestack depth imaging

Geophysical modeling of multiple geophysical parameters can take place reliably through the simultaneous joint inversion of the different geophysical domains. The desired objective is the derivation of a model expressing different geophysical properties of the Earth but, at the same time, showing consistency among the parameters. This concept, generally referred to as data integration, is widespread in geophysics but the way of achieving it is not obvious. Several authors have proposed different approaches where data, interpretation, and experience all contributed to the task. The result is that no general workflows could be defined that left ample margins for uncertainties and personal judgment.
