Title:
Overview of Inversion Approaches for Large-Scale Geophysical Measurements
Abstract:
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.
