Investigation of vendor demultiple technology for complex subsalt geology: 71st Annual International

A 2-D elastic dataset over a complex geologic model was used to investigate and benchmark demultiple processing capabilities at seven seismic processing vendors. Results show the free surface related multiple elimination (SRME) method to be superior to other methods. However, SRME did not fully solve the demultiple problem on this data. Radon methods were not an effective processing step. Other methods offer promise for extensions to 3-D, but at the risk of removing primaries. These results and the test dataset can be used by researchers to further improve subsalt demultiple algorithms.
