SEISMIC FACIES ARE IDENTIFIED IN A VOLUME OF SEISMIC DATA,WHEREIN , FIRST, A PLURALITY OF INITIAL TEXTURAL ATTRIBUTES (106) REPRESENTATIVE OF THE VOLUME OF SEISMIC DATA ARE CALCULATED. NEXT, A PROBABILISTIC NEURAL NETWORK (107) IS CONSTRUCTED FROM THE CALCULATED INITIAL TEXTURAL ATTRIBUTES. THEN, FINAL TEXTURAL ATTRIBUTES ARE CALCULATED THROUGHOUT THE VOLUME OF SEISMIC DATA. FINALLY, THE CALCULATED FINAL TEXTURAL ATTRIBUTES ARE CLASSIFIED (108) USING THE CONSTRUCTED PROBABILISTIC NEUTRAL NETWORK (107).(FIG.1)
