AVA-COMPLIANT ENHANCEMENT OF PRE-STACK FREQUENCY SPECTRUM OF SEISMIC DATA

摘要

Generating spectrally enhanced seismic data (100) expresses seismic data as a convolution of reflectivity and a seismic source wavelet (104). This seismic source wavelet varies over a sampling interval and defining a total amount of energy over the sampling interval. An enhanced seismic source wavelet that is a single-valued energy spike that yields the total amount of energy over the sampling interval is generated (112). In addition, the reflectivity is modified to preserve amplitude variation with angle (108). The reflectivity is convoluted with the enhanced seismic source wavelet (114) and residual energy is added to the convolution to generate the spectrally enhanced seismic data (116).
