The article discusses how studying deepwater deposits in Northwest Sabah, Malaysia can help understand the history of hydrocarbon reservoir sands and migration pathways. By analyzing well logs, cores, and seismic data along with outcrop sedimentology, researchers aim to uncover the depositional systems and history of these deposits. This integrated approach will provide insights into the distribution of reservoir sands, seal and source rocks, and potential migration routes in the subsurface, aiding in the identification of potential oil and gas prospects.
