The basement of the South Pattani Basin is poorly understood, as a result of low seismic resolution in its deeper part and lack of wells that reach the basement. Hence, seismic interpretation may improve the understanding of South Pattani Basin basement fracture systems. This paper aims to investigate the geological and seismic characteristics of the fractured basement reservoir, identify the relation between basin evolution and fracture network and development, and proposed a play concept for naturally fractured basement reservoir. Seismic attributes exhibit prominent N-S fault and fracture trends in the study area. Three basement high areas revealed that open fractures distribution Keywords: Fractured basement reservoir, Pattani Basin, Bu Do Granite, Pre-Tertiary DOI: https://doi.org/10.7186/bgsm73202209 0126-6187; 2637-109X / Published by the Geological Society of Malaysia. |
