Abstract
Official abstract text for this publication.
Apparatuses and methods for collecting and analyzing seismic data (D) include a frequency dependent noise factor (ε 2 ) for stabilizing a transformation matrix (S). The noise factor (ε 2 ) is a function of a number of nonzero eigenvalues of the transformation matrix (S).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for analyzing seismic data collected with one or more sensors at a plurality of sensor positions in a range along a dimension of a formation, the method comprising operating a processor to transform seismic data D into tau-p space, the seismic data D representing the formation, said transforming comprising: for each frequency: generating frequency dependent transformation matrices R that are configured to transform frequency-offset seismic da…
