Real data examples

Real data processed with the prediction prediction show results similar to the synthetic examples. It is difficult to confirm which result is better without independent information. Wavelet distortion is difficult to recognize in complex real data. Even so, the reflection amplitudes appear to be improved on the inversion prediction results when compared to the prediction-filtering results.

The first section in Figure  shows the input, a 2-dimensional line from a 3-dimensional survey. The second section in Figure  shows the result of applying a prediction filter to the data in the first panel. The results are significantly better than the input. The third section in Figure  show the results of the inversion prediction. The amplitudes on the inversion results are better preserved than the prediction-filter results. It is difficult to judge whether the events between 1.2 and 1.6 seconds are organized noise or weak reflections attenuated by the t-x prediction filter, but they are likely to be organized noise similar to that seen in the synthetic examples. Figure  shows a close-up of the data in Figure . The results of the inversion prediction are more appealing than the t-x prediction-filtering results.
