Conventional seismic migration operators produce an image that suffers from low resolution, sampling artifacts, and poorly balanced amplitudes. An improved image can be obtained by casting migration as a least-squares optimization problem in which the goal is to minimize the difference between...

Regularization of the AVO inverse problem by means of a multivariate Cauchy probability distribution
DownloadSpring 2010
Amplitude Variation with O set (AVO) inversion is one of the techniques that is being used to estimate subsurface physical parameters such as P-wave velocity, S-wave velocity, and density or their attributes. AVO inversion is an ill-conditioned problem which has to be regularized in order to...

Historically seismic data processing has relied on the acoustic approximation to process single component data under the simplifying assumption that the recorded wavefield consists mainly of compressional wave modes. With the advancement of multicomponent seismic technology there is an increased...
