Abstract
The Sarawak Basin, located offshore East Malaysia, is a mature and highly prolific hydrocarbon province that continues to attract exploration and redevelopment interest. Despite decades of seismic acquisition and processing, persistent imaging challenges remain due to the shallow-marine environment, strong multiple contamination, complex structural styles, and laterally variable, highly attenuative overburden associated with shallow gas accumulations. These factors introduce significant uncertainty in reservoir delineation, fault interpretation, and amplitude reliability, ultimately increasing exploration and development risk.
