Abstract

For several years UNOCAL Indonesia has aggressively pursued the suppression of very<br>strong multiples obscuring key oil and gas pay zones in its Kutei Basin fields in Indonesia.<br>Numerous techniques such as wave equation, high resolution radon, fk, and pattern matching<br>have been extensively tested without significant improvements in the resulting seismic<br>images. Here we report the results of a processing sequence that was successful in<br>substantially improving the deep image for frequencies up to 13 hertz in the most multipleridden<br>field, Ranggas. That processing sequence included radon followed by a depth-modelbased<br>demultiple technique (Heinze et al., 2001), which is based on a beam depth imaging<br>algorithm.
