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. ...
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 ...
Recursive Imaging with Multiply-Scattered Waves Using Partial Image Regularization: A North Sea Case Study
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
As more resources are directed toward reverse-time migration an accurate velocity
model, including strong reflectors, is necessary to form a clear image of the subsurface.
This is of particular importance in the vicinity ...
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 ...
A field expansions method for scattering by periodic multilayered media
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
The interaction of acoustic and electromagnetic waves with periodic structures plays an important role
in a wide range of problems of scientific and technological interest. This contribution focuses upon the
robust and ...
