Estimate the Effective Elastic Properties of Digitized Porous Rocks by Inverting the Cracks Unresolved
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
Current imaging technique such as micro X-ray CT can provide us detailed 3D micro-structures of porous
rocks that can be used in numerical simulation so as to predict elastic properties of rocks saturated with
different ...
Modeling of acoustic wave scattering from a two-dimensional fracture
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
In this paper, we model the acoustic scattering from a two dimensional fracture that is simulated by two different physical models. We calculate the scattering from the fractures with different properties based on these ...
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. ...
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 ...
Surface-wave eikonal tomography in a scattering environment
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
Surface waves are of increasing interest in seismic prospecting. Traveltime tomography based on
dispersion measurements is often used to process surface-wave data, but it has limitations due to the
a priori information ...
Frequency-Domain Finite-Difference Acoustic Modeling with Free Surface Topography using Embedded Boundary Method
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010)
In this paper, we present a method to model acoustic wave propagation in the frequencydomain
in the presence of free surface topography using the embedded boundary method. The
advantage of this method is to solve for the ...
Interferometric correlogram-space analysis
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2010-04-26)
Seismic interferometry is a method of obtaining a virtual shot gather
from a collection of physical shot gathers. The set of traces corresponding
to two common receiver gathers from many physical shots is used to synthesize ...
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 ...
