History matching is a type of inverse problem in which observed reservoir behavior is used
to estimate reservoir model variables that caused the behavior. Obtaining even a single …

There has been great progress in data assimilation within atmospheric and oceanographic
sciences during the last couple of decades. In data assimilation, one aims at merging the …

We give an overview of recent techniques which use a level set representation of shapes for
solving inverse scattering problems. The main focus is on electromagnetic scattering using …

We consider calculation of the Bayesian model evidence, which is an essential component
in realistic uncertainty quantification. The main motivation is large-scale porous-media-flow …

A sequential inversion methodology for combining geophysical data types of different
resolutions is developed and applied to monitoring of large-scale CO 2 injection. The …

We describe a novel technique for the characterization of structured reservoirs from
production data. A level set technique is used in order to be able to incorporate interfaces …

The truncated pluri-Gaussian model is a powerful tool for representing realistic spatial
distributions of facies in reservoir characterization. It is suitable for generating stochastic …

This paper presents a robust and efficient numerical model for the parameterization of the
hydrodynamic in fractured porous media. The developed model is based upon the …

ABSTRACT I evaluated a simultaneous joint inversion of seismic amplitude-versus-offset
(AVO) and controlled-source electromagnetic (CSEM) data for fluid-flow monitoring. A new …

A Bayesian inversion methodology for identification of large-scale subsurface structures
(strata) from controlled source electromagnetic data is developed. The Bayesian inverse …
