I017 Z-99 Azimuthal Sonic Imaging Abstract We have developed a method for generating 3D images from sonic full-waveform data. The data were acquired using the Schlumberger Dipole Sonic Imager (DSI�) tool consisting of four sets of hydrophone receivers arranged around the perimeter of the tool. Each of the four receiver banks consists of eight hydrophones placed along the borehole at ½ ft intervals. After applying adaptive noise cancellation filters and wavefield migration we obtain one image each centered on the corresponding set of azimuthal receivers. A 3D image of the formation is formed by applying spatial shifts dependent on the
