Based on an analysis of the abundance, type and thermal evolution of the organic matter from wells and cable drilling data of a block in Myanmar, the authors have revealed that the study area has certain hydrocarbon generating potential. The evaluation of 2 source rocks of the Oligocene and Miocene shale by using TOC, S2, chloroform asphalt "A", Tmax and Ro test data shows that the main source rock is Lower-Middle Oligocene, whereas middle-upper layer of Oligocene has low-middle organic abundance source rock. The type of organic matter is Ⅱ2 or Ⅲ, gas is produced in the south and oil is produced in the north. Thermal evolution in the south is higher than that in the north, and the maturity is in low-mature and early stage. It is concluded that the study area has a good hydrocarbon potential.
