Delineation of fracture anisotropy signatures in Wudayhi Field by azimuthal seismic data

Wudayhi Field, in the eastern province of Saudi Arabia (Figure 1a), is an anticlinal structure in the Paleozoic-Cenozoic rocks; it is 30 km in length and 10 km in width, and trends ENE. The Wudayhi anticline is one in a group of forced folds related to draping of the sedimentary cover over basement block faults in the eastern margin of Arabia. The anticline is asymmetric, with southern vergence, and gentle dip angles that rarely exceed several degrees.
