Tapped Delay Line Models for the Dereverberation of Deep Water Multiples

Multiple Removal Procedures based upon tapped delay line models for the reverberation are derived and applied to data taken during the NSF-IDOE-East Atlantic Continental Margin Program. The effectiveness of these models are analyzed by, i) determining the amount of reverberation energy removed, ii) evaluating the distortion of underlying horizons, and iii) comparing record quality before and after processing. Programs based upon these models have been implemented as operational production programs and are currently being used aboard the R/V Atlantic II during the EACM studies.
