Abstract
Fast anisotropy axis values are determined for each bin in seismic data binned by azimuth. A fast azimuth gather is determined within each bin in the seismic data from the fast anisotropy axis values. The earth's subsurface is imaged, using the fast azimuth gathers.
Claims14
A method for imaging earth's subsurface, comprising:
- using a programmable computer to perform the following:
- determining fast anisotropy axis values for each sample in seismic data binned by azimuth;
- determining a fast azimuth gather within each bin in the seismic data from the fast anisotropy axis values;
- and
- imaging the earth's subsurface, using the fast azimuth gathers.
