SYSTEM AND METHOD FOR ATTENUATING MULTIPLES IN SEISMIC DATA THAT ACCOUNTS FOR BEAM AZIMUTH |
摘要 |
The present invention incorporates the use of model-driven and data-driven methodologies to attenuate multiples in seismic data utilizing a prediction model which includes multiply-reflected, surface-related seismic waves. The present invention includes beam techniques that account for beam azimuth, and convolving a predicted multiples beam with a segment of a modeled pegleg beam to obtain a convolved multiples beam. The convolved multiples beam can then be deconvolved to attenuate the multiples that are present in the original input beam. |
