METHOD OF ANALYZING CAPABILITIES OF MULTIPLE-SUPPRESSION COMPUTER SEISMIC DATA PROCESSING SOFTWARE

摘要

Computer-implemented methods of processing seismic data for the purpose of suppression of multiple reflections, or multiples, are subjected to quantitative evaluation. The evaluation is done by a computerized testing procedure. A known earth model is formed. From this model, data composed of primary reflections only (100), and data containing multiple reflections (102) only are generated. These are retained separately, but a third data set representing their sum (104) is also formed to serve as an original data set for processing. The original data set or sum is then processed by the processing method (106) being evaluated. The processed results are then decomposed (108) by a time-varying, least squares technique into primaries-only and multiples-only components. The decomposed primaries-only and multiples-only components so formed are then compared (110) against the values of the original sets from the known earth model.
