Permian carbonates have very high hydrocarbon potential in Southeast Asia. At first, they have very high single-well productivity, up to MMBOs and hundreds of BCFG in cumulative. Secondly, they have thick and extensive distribution through much of the Southeast Asia. They consist the basement plays under Mesozoic basins in onshore areas represented by Sinphuhorm Field and under Cenozoic basins in offshore areas represented by Nang Nuan Field. But E&P in this play has been not successful due to the limited knowledge on the extreme and extensive heterogeneity in Permian carbonate. The advance carbonate reservoir characterization in these two field has illustrated that large cavities (caves) are the main contributor to the high productivity and their uneven distribution in tight matrix leads to highly uneven distribution of reserves and productivity in carbonate reservoirs. The surface and subsurface G&G data has illustrated that caverns are widely distributed in both orogeny and basin provinces of Southeast Asia. With proper knowledge and approach, Permian carbonates will become an important play in Asia petroleum E&P.
