[Alumnos] SEG Distinguished Lecture 2018

[Sociedad Geofísica de la UNLP]

La Sociedad de Alumnos de Geofísica de la FCAG-UNLP (SEG Student Chapter) 
tiene el agrado de invitarlos a participar de la charla titulada "Advanced 
imaging for practitioners". La misma estará a cargo del Prof. William W. 
Symes, y se desarrolla en el marco del "Distinguished Lecture Program" 
organizado por la Sociedad de Geofísicos de Exploración (SEG).
La charla tendrá lugar el lunes 9 de abril a las 10.30 hs., en el Salón 
Meridiano de la FCAG.

Los esperamos!!


Resumen de la charla:
Seismic migration has been a core geophysical technology for more than 50 
years and continues to evolve in its capacity to reveal detailed 
quantitative information about the sedimentary earth. Integration of ever 
more accurate and complete seismic wave physics, more precise numerical 
methods, and rapidly improving computer hardware and software environments 
have made formerly “advanced” methods such as prestack reverse time 
migration (RTM) relatively routine.
This lecture will discuss two variants of RTM aimed at enhancing the 
significance of image amplitudes. Both true amplitude migration and least 
squares migration (LSM) are being actively researched; singly and in 
combination, they have many applications, some surprising. I will describe 
a number of these applications and illustrate them using synthetic and 
field data examples.


Biografía:
William W. Symes graduated with honors from the University of 
California--Berkeley in 1971 and received a PhD in mathematics from 
Harvard University in 1975. After research and teaching positions at 
University of British Columbia, University of Wisconsin, and Michigan 
State University, in 1983 he joined the faculty of Rice University, where 
he currently is Noah G. Harding Professor Emeritus and Research Professor 
in Computational and Applied Mathematics. He also has been a faculty 
member in Rice’s Department of Earth Science. He has worked in many areas 
of applied and numerical mathematics, including numerical methods for wave 
modeling, scientific software engineering, and theory of, and algorithms 
for, seismic inversion. He has developed grid-based eikonal solvers, data 
compression and multi parameter inversion algorithms, efficient 
viscoelastic modeling methods, QC methods for finite difference modeling 
(as part of the SEG’s Phase I SEAM project), optimal check-pointing for 
RTM and FWI gradient calculation, wave equation based acceleration of 
iterative least squares migration, and the extended modeling / 
differential semblance concept for seismic velocity estimation. To better 
explore these topics in an industrial context, Symes founded a research 
consortium, The Rice Inversion Project, which has been sponsored for more 
than 25 years by firms in the oil and computer industries, and has 
supported the studies of more than 40 MA, PhD, and postdoctoral students. 
Among other honors and awards, Symes has received the Ralph E. Kleinman 
and Geoscience Career awards from SIAM and is a SIAM Fellow (inaugural 
class) and Fellow of the Institute of Physics. In 2015, he received the 
Desiderius Erasmus prize from the European Association of Geoscientists 
and Engineers for his “seminal contributions to methods, analysis, 
algorithms, and software for seismic inversion and wave propagation…”.
