The maximum water depth in Beibu Gulf is less than 200 m and it is getting deeper towards the south when it is open up to the South China Sea. A number of wells have been drilled in this area with oil and gas discoveries (Fig. 2). Several seismic lines were published:
A & B are perpendicular to Red River Fault system.
C is parallel to the Red River Fault system.
