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 …

The Earth below ground is the subject of interest for many geophysical as well as geological
investigations. Even though most practitioners would agree that all available information …

Geophysical inversion methods are used as part of an interpretation process that seeks to
differentiate geologic units. To improve the reliability of geologic differentiation based on …

For 3-D inversion of controlled-source electromagnetic (CSEM) data, increasing availability
of high-performance computers enables us to apply inversion techniques that are …

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

Electrical resistivity tomography (ERT) is based on solving a Poisson equation for the
electrical potential and is characterized by a good sensitivity only in the vicinity of the …

The non-uniqueness of the underdetermined inverse problem requires that any available
geological information be incorporated to constrain the results. Such information commonly …

Turbulent flow simulations based on the Reynolds-averaged Navier–Stokes (RANS)
equations continue to be the workhorse approach for industrial flow problems. However, due …

We have developed a joint geophysical inversion workflow that aims to improve subsurface
imaging and decrease uncertainty by integrating petrophysical constraints and geologic …

Gravity inversion has become the main method to obtain the 3-D density distribution in the
exploration of petroleum and mineral resources as well as the study of geological structure …
