The Pre‐Khorat play in the Northeastern Thailand

Complexity of the NE structure challenged enthusiastic explorers to concentrate on the Permian carbonate reservoir which happened to be only one petroleum play ,proved for commerciality in the NE Thailand.

Conclusions

1. understanding the dynamic of petroleum system and geological risk identification are still keys to success in the NE region of Thailand.

2. Usage of the NE analogy set as prototype for input parameters in unexplored areas allows petroleum potential of the areas to be determined.

3. In the Gulf of Thailand and the North-Central Area, key to success is to integrate EOR technologies and put more effort through geological concept.

4. Regional study of each petroleum province will be able to allow synergic strategy for developing brown field and it possibly bring marginal field to live.
