Experimental studies of the acoustic wave field near a borehole
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
A monopole or a dipole source in a fluid borehole generates acoustic waves, part of which propagate along the borehole and the other part enter the formation propagating as P- or S-waves. The refracted waves propagating ...
3D Weak-Dispersion Reverse-Time Migration with a StereoModeling Method
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
The finite difference method has been widely used in seismic modeling and reverse time migration. However, it generally has two issues: large computational cost and numerical dispersion. Recently, a nearly-analytic discrete ...
Reverse Time Migration in the presence of known sharp interfaces
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We propose using the forward propagated source wave to create synthetic receiver data on the surfaces of the computational domain where real receiver data is not available as a means of exploiting known information about ...
