We present our results on amplitude-preserved data processing and analysis of the Mobil AVO data set. First, we apply a source and receiver consistent amplitude balancing to the seismic data, which reduces source and receiver amplitude variance from about 8% and 15%, respectively, to within a few percent scatter. Next, we apply a time-domain conjugate-gradient multiple-suppression technique to remove multiple reflection energy and simultaneously preserve and enhance primary reflection AVO amplitudes. We perform unmigrated AVO analyses and find that the multiple-suppressed data correlate better with the well-log data than the unprocessed data. A prestack migration/inversion of the multiple-suppressed data...

Comparison of Seismic Inversion Methods on a Single Real Data Set
Papers in this volume explore the potential of a variety of seismic inversion methods applied to the same data set. They cover a wide range of topics, including effects of rock properties on seismic response, preparation of seismic data for AVO analysis, and a variety of AVO and inversion methods. The papers are an extension of a 1994 SEG postconvention workshop.
