Abstract:

The Phu Khanh Basin of eastern Vietnam is one of the last remaining basins in SE Asia that is truly a frontier with the total area of about 110,000 km2. The exploration of this basin initiated earlier in the inboard shallow water area of the basin rather than the deepwater area. Seismic surveys of 2D and 3D have been shot and several wells have been drilled in the shallow areas. As a result, a working petroleum system has been proven. However, the exploration in the deepwater area (>200m) has been just began in recent years with only seismic acquisition. Exploration well in this area is yet to be drilled therefore petroleum system still owns a large uncertainty. The seabed coring, and heat Flow research in the block 144-145 deepwater area was designed and done to assess the presence of a potential working petroleum systems. This paper provides the main results of the research including: biostratigraphy, Isotopes, biomarkers, diamondoids, hard substrate and heat flow. Analytical results from the program will assist basin modeling and assess the uncertainty of the petroleum system.
