Physics
and
Simulation
of
Waves
for
Exploration
and
Environmental
Geosciences
|
 |
| 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. |

| Biography |
José
M.
Carcione
was
born
in
Buenos
Aires,
Argentina
in
1953.
He
received
the
degree
Licenciado
in
Ciencias
Físicas
from
Buenos
Aires
University
in
1978,
the
degree
Dottore
in
Física
from
Milan
University
in
1984,
and
the
Ph.D
in
geophysics
from
Tel-Aviv
University
in
1987.
From
1978
to
1980
he
worked
at
the
Comisión
Nacional
de
Energía
Atómica
at
Buenos
Aires.
From
1981
to
1987
he
was
employed
as
a
research
geophysicist
at
Yacimientos
Petrolíferos
Fiscales,
the
national
oil
company
of
Argentina.
Presently,
he
is
a
senior
geophysicist
at
the
Istituto
Nazionale
di
Oceanografia
e
di
Geofisica
Sperimentale
(OGS),
formerly
Osservatorio
Geofisico
Sperimentale
in
Trieste.
He
was
awarded
the
Alexander
von
Humboldt
scholarship
for
a
postdoc
at
Hamburg
University,
where
he
stayed
from
1987
to
1989.
In
2007,
he
received
the
Anstey
award
at
the
EAGE
in
London.
José
Carcione
has
published
more
than
160
journal
articles
on
acoustic
and
electromagnetic
numerical
modeling,
with
applications
to
oil
exploration
and
environmental
geophysics.
He
is
the
author
of
the
book
Wave
fields
in
Real
Media
-
Theory
and
numerical
simulation
of
wave
propagation
in
anisotropic,
anelastic,
porous
and
electromagnetic
media
(Pergamon
Press,
2001;
Elsevier
Science,
2007)
and
co-author
of
Arqueo-geofísica:
Una
metodología
interdisciplinaria
para
explorar
el
pasado
(Fundación
de
Historia
Natural,
2006).
He
has
been
an
editor
of
GEOPHYSICS
since
1999.
