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 el jueves 10 de septiembre a las 16 hs. en el salón
Meridiano.

Además queremos contarles que esta misma charla se dará el martes 8 de
septiembre a las 11 hs., en el Hotel Continental (Salón Avant Garde III)
organizada por la Asociación Argentina de Geólogos y Geofísicos Petroleros
(AAGGP).



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 velocity
models 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.
