Intrusive and metamorphosed rocks of various ages and sources underlying Tertiary sediments of the Cuu Long and Nam Con Son Basins are commonly given the generic denomination of "Basement rocks". Basement rocks have been encountered in a large number of wells drilled in various areas of the South Vietnam Continental Shelf. Within the Bach Ho, Cuu Long and Dong Nai Fields of the Cuu Long Basin, and the Dai Hung Field of the Nam Con Son Basin, Basement is hydrocarbon-bearing with significant potential. Many exploration and production wells within these fields have penetrated from 100m to 1500m into Basement. A number of studies have been undertaken by oil companies, including interpretation of 3D seismic data and borehole image data, determination of formation PVT characteristics, and study of fracture types and lithological composition, to assist reserve calculations and reservoir and production profile design. Based on an overview study of data, and analytical results from the two basins using global and comparative methodologies, the report highlights the following: Basement composition in the Cuu Long and Nam Con Son Basins, Basement fractures and Basement reservoir properties in producing oil fields.
