In addition, acoustic impedance inversion allows direct interpretation of three-dimensional geobodies. Volumetric and property cut-offs may be applied to rank multiple prospects. Recent advances in seismic inversion include inversion of multiple offset data volumes and model based geostatistical inversion. Rick Davison earned his Ph.D. in 1988 at Virginia Tech. He worked as a geophysical interpreter for Arco and Vastar Resources for 10 years before joining Jason Geosystems.
Seismic coherence is an extremely powerful tool in mapping faults and other edges.
Amplitude gradients highlight changes in reflector strength resulting from variation in lithology or fluid content. None of these multitrace attributes require prior interpretation of the 3D seismic data cube. I will demonstrate the application and effectiveness of these attributes in exploration and production case studies from around the world. Biography Kurt Marfurt began his geophysical career as an Assistant Professor teaching mining geophysics at Columbia University s Henry Krumb School of Mines in New York. After 5 years he joined Amoco at what was then called their Tulsa Research Center.
