Overview of Inversion Approaches for Large-Scale Geophysical Measurements

In this presentation we review a number of inversion approaches for large-scale geophysical applications arising in oil exploration, such as cross-well measurements, surface-to-borehole, single-well, and surface EM. We will present a number of approaches that cover both model-based parametric methods and pixel-type imaging schemes. Much of the challenges facing these types of applications are related to the large computational cost of the forward modeling and the inherent non-uniqueness associated with the inversion of these measurements. We will cover some of the regularization approaches that can help in narrowing down the class of solutions that may have physical and practical usefulness. If time allows, we will also cover joint multi-physics inversion for the integration of electromagnetic with seismic or pressure measurements.
