<h2>Agenda Semanal de Ciencia y Técnica</h2>
Este es el resumen de las actividades científicas que tendremos la
próxima semana en nuestra Facultad.<br>
<br>
<br>
<p style="text-align: center;"><strong>Lunes 27 de agosto - 15:30hs
- Salón Meridiano</strong></p>
<p style="text-align: center;"><strong>Charla SEG: "H</strong><strong>ow
recent advances in seismic depth imaging can enhance prospect
identification and appraisal."</strong></p>
<p style="text-align: center;">Dr. Ruben D. Martinez</p>
<p style="text-align: center;">Petroleum geoscience consultant and
instructor en Reservoir Geoscience, LLC.</p>
<p style="text-align: center;"> </p>
<p style="text-align: justify;">Resumen de la charla: Seismic depth
imaging has matured and become a powerful tool in petroleum
exploration to accurately map complex structural frameworks. In
particular, over the last few years, more accurate seismic imaging
methods have emerged leading to increased resolution of velocity
models and seismic images. High-resolution velocity models and
images enhance the accuracy and value of interpretation not only
in exploration but also in the appraisal phase and, in some cases,
field development planning. So how is this high resolution
achieved? Velocity model resolution improvement is achieved by
extracting the information content of the seismic amplitudes and
phases, in addition to the traveltimes, using advanced methods
such as full waveform inversion (FWI). FWI velocity models have
resolutions beyond those obtained from classical traveltime
tomography.</p>
<p style="text-align: justify;">High-resolution velocity models
deliver not only more accurate structural images after
conventional migration (Kirchhoff, Beam, WEM, or RTM) but they
also can be used to enhance prospect identification, prospect
appraisal and to de-risk drilling by using advanced migration
methods such as Q migration (QPSDM), imaging of primaries and
multiples, diffraction imaging, and least squares migration
(LSPSDM). It is important to recognize that all conventional and
high-resolution velocity model building and migration techniques
should also incorporate different types of seismic anisotropy
depending upon which one fits best the geologic scenarios present
in the areas of study. In this lecture, I will provide an overview
of the most popular conventional and high-resolution anisotropic
velocity model building and migration techniques used in the
industry. The strengths and weaknesses of these techniques will be
discussed, and illustrated, to understand their resolution
limitations.<br>
I will also discuss and illustrate, with model and real data, the
performance of these depth-imaging techniques according to the
resolution requirements for the geologic scenarios commonly
encountered in conventional and unconventional prospect
identification and appraisal with the aim of de-risking drilling.
The lecture will end with comments on my expectations about the
future of depth-imaging technology and its impact on conventional
and unconventional petroleum exploration, appraisal, and
development.</p>

<p style="text-align: center;"><strong>Miércoles 29 de agosto -
13:00hs - Salón Meridiano </strong></p>
<p style="text-align: center;"><strong>Seminario
FCAG: "Problemáticas abiertas en la astrofísica de los restos de
supernova."</strong></p>
<p style="text-align: center;">Dra. Gabriela Castelletti </p>
<p style="text-align: center;">Instituto de Astronomía y Física del
Espacio (IAFE, CONICET-UBA).</p>
<p> </p>
<p style="text-align: justify;">Resumen: En los restos de supernova
(RSNs), creados tras la violenta explosión de la estrella
progenitora, los procesos radiativos no térmicos revelan la
existencia de partículas energéticas interactuando con campos
magnéticos, radiación y/o material interestelar. El estudio
multifrecuencia de estas fuentes, incluyendo tanto datos
astronómicos como desarrollos teóricos, es fundamental para
comprender las complejas condiciones bajo las cuales se produce la
emisión observada. Si bien en las últimas décadas se han alcanzado
avances significativos, aún existe un controvertido debate sobre
diversas cuestiones relativas a la tasa de explosiones estelares,
el rol de los RSNs como aceleradores cósmicos y su interacción con
el medio circundante. En esta charla, a través de un recorrido
sobre la información observacional y teórica actual, se discuten
tales problemáticas y los posibles caminos planteados para
resolverlas.</p>
