Early
estimation of principal S-wave orientation is critical for
processing.
Alford
rotation analysis is a valuable tool to quantify the
time variant S-wave birefringence.
More
intense azimuthal anisotropy on the crest and flanks of the
Pinedale anticline suggest potential fracture sweet spots.
Fast
S-wave direction agrees with the strike of near vertical fractures
on the FMI log, and appears to be sensitive to local horizontal
stresses.
