Abstract

Summary

Imaging the subsurface for potential hydrocarbons is pivotal in the industry, primarily utilizing seismic and non-seismic methods (e.g., Gravity, Controlled Source Electromagnetic data). While seismic data offer crucial initial insights into the subsurface, challenges persist due to complexities like intricate fault systems and Shallow Gas, which often hinder the imaging process in Malaysia Basins. A promising solution involves using Ocean Bottom Nodes (OBN) for seismic acquisition, as they effectively handle subsurface complexities, particularly those masked by Shallow Gas. Techniques like Full Waveform Inversion and Reverse Time Migration further enhance imaging in these challenging zones, offering unprecedented clarity. Our study demonstrates that integrating Geology and Geophysics with Petroleum Engineering significantly advances our understanding of the subsurface in longstanding production fields in Malaysia. This multidisciplinary approach has unveiled crucial data regarding reservoir characteristics, fluid contact, Behind Casing Opportunity, and infill opportunities, essential for unlocking the potential of both shallow and deep reservoirs. This integrated method not only informs better decision-making but also ensures quicker project turnaround and maximizes the extraction of remaining hydrocarbons.
