P116 DETECTION OF SHEAR-WAVE SPLITTING AND FRACTURE ORIENTATION FROM PS WAVES AT THE VALHALL FIELD MIN LOU YAOHUI ZHANG and LONG DON PHAM 1 PGS Research Division 738 Highway 6 South Suite 300 Houston TX 77079 USA Abstract We present a two-component rotation/cross-correlation method to detect shear-wave splitting and fracture orientation from PS converted waves. By analyzing a set of synthetic data and a set of 2D-4C ocean bottom cable (OBC) field data recorded on the Valhall field North Sea our results demonstrate that the two-component rotation/cross-correlation method is robust to detect shear-wave splitting and its implied fracture orientation and
