Abstract
A new antimultiple software has been developed by E. Verschuur (1991) and industrialized by TNO and TOTAL. This is a surface related multiple elimination technique which uses the seismic data itself to predict and subtract all the multiples related to the free reflecting surface. A benchmark test was performed to compare five contractors wave equation based antimultiples with our new technique. The benchmark has shown that this new technique has effectively attenuated numerous strong peg-leg multiples in the interval of interest (2.0-3.5 sec) where it compares favorably with the other methods results. The water bottom multiples and the deep multiples (below 3.5 sec) have only been slightly attacked. Some tests have shown that we can improve the present results by applying a refined near offsets data interpolation and an XT least squares filtering that ameliorates the adaptative multiple subtraction.
