Multiphysics imaging or data inversion is of growing importance in many branches of
science and engineering. In geophysical sciences, there is a need for combining information …

A meaningful solution to an inversion problem should be composed of the preferred
inversion model and its uncertainty and resolution estimates. The model uncertainty …

We have developed a frequency-domain joint electromagnetic (EM) and seismic inversion
algorithm for reservoir evaluation and exploration applications. EM and seismic data are …

Joint inversion of multiple geophysical data has become an active area of research due to its
potential to greatly enhance the fidelity of inverted models. Many open questions and …

We extend the cross-gradient methodology for joint inversion to three-dimensional
environments and introduce a solution procedure based on a statistical formulation and …

Predictive groundwater modeling requires accurate information about aquifer
characteristics. Geophysical imaging is a powerful tool for delineating aquifer properties at …

Inverse problems are inherently non-unique, and regularization is needed to obtain stable
and reasonable solutions. The regularization adds information to the problem and …

Hydraulic tomography is a field scale aquifer characterization method capable of estimating
3‐D heterogeneous parameter distributions, and is directly sensitive to hydraulic …

SUMMARY A big potential lies in the quantitative integration of multiple geophysical
measurements for what concerns more unique and robust inversion results, complementary …

In this review, I discuss the basic principles of joint inversion and constrained inversion
approaches and show a few instructive examples of applications of these approaches in the …
