Play and Hydrocarbon Potential of the Khorat Plateau Basin in Thailand
Aiming to address the low degree of exploration and lack of data, we have studied play and resource potential using the Khorat Plateau Basin, Thailand, as an example. Under the framework of the progressive control of tectono-sedimentary evolution on hydro-carbon accumulation, several conclusions have been drawn as follows. First, from the Neopaleozoic to the Cenozoic, the basin was divided into two tectonic sequences:TS1 and TS2. Nearshore, shelf, and carbonate platform sediments of shallow water facies are filled within the framework of TS1;alluvial fan, fluvial, and lacustrine sediments of continental facies are filled within the framework of TS2. There are two main source-reservoir-cap rock combinations in the basin, controlled by sedimentary facies distribution. Considering the major trap types and characteristics of the reservoir-cap rock assemblage in the basin, two first order plays and four second order plays are further differentiated. In the future, gas exploration should be directed at the proven Permian first order play. Horizontally, special attention should be paid to the regions favorable for the exploration of petroleum.
