Regional map of Andaman Sea which located western offshore Thailand. This region is divided into shallow and deepwater part. The Megui Basin is situated mainly in the deepwater with water depth range from 200 meters to 3 kilometers. The Mergui basin has three main sub-basins: the Western Mergui, Eastern Mergui and Ranong Trough. The Western Mergui and Eastern Mergui sub-basins are separated by the Central High. Sedimentary thickness is estimated up to 10 km in depocenter. The Mergui Basin is the only one Tertiary basin in Thailand that sediment are ttruely marine origin. The basin connect to the North Sumatra to the south. Review of Regional of Nort Sumatra and Mer Gui Basin in Thailand side,

Presentation Notes
Ranong Formation is classified to be a good reservoir in the Mergui Basin. It was deposited by fluvio-deltaic and shore face sand whilst the Yala Formation is marine shale and turbidite facies. Kantang is dominantly deposited in deep marine shales in the basin center. Tai is a carbonate facies locally deposited around the structural high. Payang is mostly sandstone and shale of delta front round the basin margins. Trang is deposited in very low energy of bathyal environment whereas Surin is a shallow marine (delta front or offshore bar). Thalang is also deposited in very energy of lower bathyal environment. Takuapa is deposited in marine shelf at the lower part whilst shallow marine on the upper part.
