Method of processing geophysical data to compensate for earth filter attenuation

摘要

Method to process seismic data to yield useful information regarding the subsurface area explored. Generated seismic energy travels into a subsurface formation where it is distorted and attenuated. The distorted and attenuated seismic pulse is detected by a geophone or other seismic receiver and recorded. The received seismic traces are first compensated for the attenuation effects of the earth filter and the compensated seismic traces are then used to produce a close approximation of a zero-phase, band-limited output wavelet of the reflectivity of the geophysical formation under exploration.
