| description | Fractures scatter seismic energy and this energy can be analyzed to provide information about fracture
direction and density. Laboratory and numerical (finite difference) models of fractures show that scattered
energy varies with the seismic acquisition direction relative to the orientation of parallel fracture sets. Data
acquired normal to fracture strike displays forward and backscattered energy that is canceled in the stacking
process, while data acquired parallel to the fracture strike contains forward scattered and guided waves that
are enhanced by stacking. The Scattering Index method estimates the fracture orientation by comparing
wavelet changes in the data from azimuthal stacks. Fracture density or spacing can be estimated by
spectral methods that include f-k analysis of backscattered energy or analysis of spectral notches as
functions of azimuth. Application of these methods to data from a fractured carbonate field results in
fracture orientation and density estimates that are consistent with borehole measurements. |
