Speaker: Leon Thomsen, Chief Scientist, Delta Geophysics
Does it make any sense to analyze Amplitude Variation with Angle even while ignoring Velocity Variation with Angle (aka anisotropy)? The short answer is No. A longer answer includes an explanation of why we have been able to "succeed" with isotropic AVO anyway, and how we can expect to do better, using a newly available workflow for doing anisotropic AVO.
Speaker Biography: Leon Thomsen, Delta Geophysics
Leon Thomsen holds degrees in geophysics from Caltech (BS, 1964) and Columbia (PhD, 1969). Following academic appointments at CNRS Paris 1969-70), Caltech (1970-72), and SUNY Binghamton (1972-80), his industrial appointments included Amoco (1972-1999) and BP (1999-2008). Following retirement from BP, he serves as Chief Scientist of Delta Geophysics (https://urldefense.proofpoint.com/v2/url?u=http-3A__DeltaGeophysics.net&d=CwICAg&c=uGuXJ43KPkPWEl2imVFDmZQlhQUET7pVRA2PDIOxgqw&r=MwSENyG9O-G9R7mi1UZsoQ&m=VbZFnPPPWOGEotcG0vQXb0xuoC4IyxtS3Nrf-d-P4fQ&s=XaAW_y-ERd1EWkxD0rUYdB_fSVQZwqoVIG8KBq7lJEk&e= ), as Research Professor at the University of Houston, and as Visiting Scientist at Lawrence Berkeley National Laboratory.
Thomsen has led technical development in applied geophysics through innovation in vector seismics (polar anisotropy, azimuthal anisotropy, azimuthal AVO, converted waves, and Life-of-Field-Seismics); in pore-pressure prediction; and most recently in ISEM and anisotropic rock physics, through numerous SEG publications and presentations, and many patents.
Thomsen was an early recipient (1960-64) of an SEG Scholarship. He received SEG's Fessenden Award in 1994. He served as SEG Distinguished Lecturer in 1997 and as SEG/EAGE Distinguished Instructor in 2002. He is an Honorary Member of GSH and of EAGE. He is a Foreign Member of the Russian Academy of Natural Sciences, and holder of their Kapitsa Medal. He served SEG as Vice President, as President-Elect, and as President (2006-07). He currently serves on the SEAM Board of Directors.
