[Antonio Trípodi]

Sres. Docentes-Investigadores, Graduados y Alumnos:

Se invita a todos a concurrir a la conferencia que brindará el Dr. José M. 
Carcione del Instituto Nazionale di Oceanografia e di Geofisica 
Sperimentale de Trieste, Italia.

Título: "Physics and Simulation of Waves for Exploration and Environmental 
Geosciences"

Fecha y hora: 13 de marzo a las 15,00 Hs.

Lugar: Salón Meridiano de la Facultad de Ciencias AStronómicas y Geofísicas de 
la UNLP. Paseo del Bosque s/n, La Plata.

La conferencia se enmarca en el programa "SEG's 2009 Central & South America 
Honorary Lecturer (HL)", está auspiciada por la SEG (Society of  Exploration 
Geophysicists) y coordinada localmente por la Sociedad Geofísica de la 
Universidad Nacional de La Plata (capítulo estudiantil de la SEG) y la Facultad 
de Ciencias Astronómicas y Geofísicas de la UNLP. Se adjunta en el presente la 
biografía del Dr. José M. Carcione.

Debido al reducido espacio físico del lugar, se ruega confirmar 
asistencia.

RESUMEN:
Use of wave modeling and inversion for the interpretation of the 
characteristics of rocks and geologic formations requires the understanding of 
the relationship between the seismic attributes and the rock properties. In 
particular, in the exploration of oil and gas reservoirs, it is important to 
predict the porosity, the presence of fluids (type and saturation), the 
preferential directions of fluid flow (anisotropy), the presence of abnormal 
pore pressures (overpressure), etc. These microstructural properties and the 
in-situ rock conditions can be obtained, in principle, from the seismic 
attributes, using realistic constitutive equations.

This lecture briefly outlines the physics and simulation of wave propagation in 
anisotropic, anelastic, and porous media, including the analogy between 
acoustic waves (in the general sense) and electromagnetic waves. Most of the 
numerical techniques have been recently developed; for instance, the solution 
of the poro-viscoelastic wave equation for reservoir seismics, and the 
domain-decomposition methods for wave propagation at the ocean bottom.

The applications include evaluation of methane hydrate content, upscaling 
techniques, detection of overpressure, propagation in permafrost, exploration 
of the Earth's deep crust, time-lapse seismics for monitoring of CO2 
sequestration, borehole stability, the mesoscopic loss mechanism in rocks, 
geo-radar applications, and low-frequency electromagnetic prospecting in the 
Earth. The emphasis is on geophysical applications for seismic exploration, but 
researchers in the fields of earthquake seismology, rock physics, and material 
science - including many branches of acoustics of fluids and solids (acoustics 
of materials, nondestructive testing, etc.) - may also find the presentation 
useful.
