La Sociedad de Alumnos de Geofísica de la UNLP (SEG Student Chapter) tiene
el agrado de invitarlos a participar de la charla titulada "Full-waveform
inversion: Challenges, opportunities, and impact". La misma  estará a cargo
del Dr. Dimitri Bevc, y se desarrolla en el marco de las "Distinguished
Lectures" organizadas por la Sociedad de Geofísicos de Exploración (SEG).
La charla tendrá lugar mañana jueves 10 de septiembre a las 16 hs. en el
salón Meridiano.

Los esperamos!!

Resumen de la charla:

There has been a great deal of industry activity and interest in
full-waveform inversion (FWI) because of its potential to generate accurate
high-resolution velocity models. Theoretically, the method has great
promise, and computer power seems to be adequate to bring this promise to
bear on practical business problems. The promise is not limited to
velocitymodels alone but also includes the possibility of inverting for
elastic parameters and rock properties and of FWI becoming an imaging
method in itself. Indeed, many of the velocity models that are routinely
attained from FWI are interpretable in themselves and could rival migration
imaging in terms of resolution and information content.

After a brief overview of FWI, this presentation will focus mostly on what
FWI can attain and will examine where and how FWI can impact business
decisions. Through an examination of imaging challenges and examples, I
will illustrate where FWI is working and bringing value ? under what kind
of geologic situations and under what kind of data acquisition scenarios.
We will examine the challenges to successful deployment of FWI and what
steps can be taken to ameliorate those challenges. The discussion should
shed light on the question of when FWI can add value and what impact this
technology can have.

During the presentation, I will examine the current technical challenges
and will explore the path to meet those challenges in the near term.
Finally, I will touch on the long-term future promise of FWI beyond
velocity estimation: What might it solve for us and how might it change the
way we work and the type of information we can get from recorded seismic
wavefields?



Biografía:

Dimitri Bevc is a team leader in geophysics R & D at Chevron. He has a
Ph.D. in geophysics from Stanford University and M.Sc. and B.A. degrees
from the University of California, Berkeley. He has been engaged with
innovating wave-equation and velocity technologies since cofounding a
start-up company immediately after completing his Ph.D. He is now doing the
same and more at Chevron.

In addition to full-waveform inversion, Bevc's technology interests include
integrating geophysical methods with geomechanics and reservoir
engineering, with applications to exploration, subsurface integrity,
containment, and reservoir management. Bevc is active on the SEG Research
Committee and has organized numerous summer research workshops and
postconvention workshops,including a popular series of imaging challenges
at the last three SEG annual meetings.
