The primary only imaging condition (POIC) is tested on 2-D SMAART JV data associated with a complicated velocity model. This data set is one of the most difficult for any demultiple algorithm. Results indicate that POIC is effective in attenuating some free surface and peg-leg multiples. Images show effective attenuation of strong multiple energy, but, POIC does not work well for multiples with weak energy such as interbed multiples and the multiples associated with the dipping bottom boundary of the salt bodies. The next step is to adjust POIC to handle these weaker events.
