Seismic interpretation and sequence stratigraphy of the Phu Khanh Basin offshore Vietnam / Telakavati Lekshmanan

The Phu Khanh basin in offshore Vietnam is a frontier basin which has never been drilled. Seismic study study of Phu Khanh basin seismic indicates that it is a typical rift basin which comprises; 1) pre-rifting 2) rifting and basin inversion and finally 3) postrift sedimentation. Pre-rifting may...
