The Application of Improved AVAZ Method in Predicting the Fractured Reservoir

  • Nowadays, it is effective to predict the fracture attributions via AVAZ technique based on pre-stack azimuthal data. However, in the seismic acquisition of narrow azimuth, the number of folds can hardly be consistent at different azimuth directions, so that different azimuth data has different energy resulting in the trend error in the prediction of fracture attributions. In this paper, the AVAZ method based on the amplitude normalization in the fractured reservoir is proposed. By adding the method into the fracture analysis step the trend error caused by the seismic acquisition could be avoided. Finally, the application results from real data shows that this method is effective and practical and it significantly improves the fracture predicted results.
