ABSTRACT:
Balancing of signal amplitudes in recorded seismic data prior to its transformation from its original domain (such as offset-time, or X-T) to a different domain (such as frequency-wave number, or F-K) has been found to cause unwanted repetitive pattern dispersion in the data. This unwanted effect is removed by determining a corrective factor, the ratio of amplitude of the seismic data to its trace envelope, prior to transformation. The data is then transformed into the different domain where meaningful reflection content is enhanced, such as by two-dimensional filtering. The data is then inverse transformed to the original domain. An inverse corrective factor is then applied, restoring the amplitude of the reflection signal component of the data.
