| Abstract | Analogues of fluvial channel systems were built for a better understanding of sand distribution and reservoir complexity, especially in isolated Early to Middle Miocene sand bodies, in the Nong Yao area on the south-east flank of the Pattani Basin in the Gulf of Thailand. Stratal slicing illustrated the complexity of the amalgamated and isolated fluvial systems where five channel styles were identified, including (1) large channel meander belts, (2) high-sinuosity large channels with large point bars, (3) low-sinuosity small channels with narrow point bars, (4) incised-channel fills and (5) tidal creeks. The best reservoir potential in the study area is in large channel meander belt systems which have high volumes and good connectivity, porosity and permeability. High-sinuosity large channels with large point bars are a secondary reservoir target while low-sinuosity small channels associated with narrow point bars have the smallest volumes and limited connectivity. |
