Abstract

Summary

With increasing hydrocarbon exploration in deepwater regions, the need to acquire accurate seismic data becomes much more important. One of the main challenges in acquiring seismic data in this area is the presence of internal multiple. This seismic multiples are usually considered as insignificant compared to the surface-related multiples, however if the target areas lies in a deeper region, it becomes much more prominent due to the weaker primary reflections. If this type of seismic noise is not handled correctly, it can effect the seismic reservoir and characterization and thus increasing the risk in oil exploration. Therefore a more advanced method needs to be applied, and one such method is the inverse scattering series. This method is data-driven therefore unlike other internal multiple attenuation technique, its does not require any prior information of the subsurface to predict the multiple. The application of this method in offshore Malay basin shows significant results, as the seismic data produced shows an improvement with a cleaner image compare to the one without any internal multiple removal.
