Abstract

Summary

Azimuthal Shear Wave Anisotropy Analysis is based on angular energy contributions from on and off axis dipole tool components. Depending on tool geometry, the number of the receivers that participate in computations varies from 6 to 11. Since the fast shear azimuth is usually only weakly variant with depth, the cross correlation of the angular energy distributions from multiple stations can be computed. This allows one to estimate standard deviation and measure correlation of the angular energy distributions. Other quality measures are also available.
