Summary Four azimuth-sectored 3D P-P volumes were pre-stack time migrated (PSTM) using the same velocity field. These high-fold data (4,000-5,000 traces were summed in each bin in each azimuth sector) of high S/N enable azimuthal analysis of amplitude, phase, frequency, and other seismic attributes. These high-fold azimuth-sectored PSTM 3D data enable us to make maps of azimuthal instantaneous phase (Top/Reservoir; Base/Reservoir) as well as to layerstrip instantaneous phase and remove the effect of the overburden, in order to see the properties of the reservoir interval. The E-SE natural fracture azimuths seen at Well A in the reservoir unit are also observed in the azimuth of the interval (layer-stripped) instantaneous phase, the sole attribute (so far) to tie well control.
