Detecting medium changes from coda by interferometry
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
In many applications, sequestering CO[subscript 2] underground for example,
determining whether or not the medium has changed is
of primary importance, with secondary goals of locating and
quantifying that change. We ...
Using SVD for improved interferometric Green’s function recovery.
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
Seismic interferometry is a technique used to estimate the
Green’s function (GF) between two receiver locations, as if
there were a source at one of the locations. By crosscorrelating
the recorded seismic signals at the ...
Interferometric imaging of multiples in an RTM approach
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
It is well known that reverse-time migration is capable of correctly
imaging multiply scattered energy. To do this, one of the interfaces
from which the waves scatter must be included in the background velocity
model. ...
