Nam Con Son basin is one of the most prolific oil and gas rich basins in Vietnam. Oil and gas is produced in a number of fields, . Dai Hung, Hai Thach/Moc Tinh, Lan Tay/Lan Do, Dua/Chim Sao and Rong Doi/Rong Doi Tay. Despite many successful wells, there are opportunities to improve exploration CoS (chance of success) in a basin by better prediction of trap definition, reservoir and seal risks. This paper presents the use of advanced 3D broadband data to help better understanding the exploration prospectivity in the centre of the Nam Con Son basin. | Better exploration prospectivity understanding through the use of advanced 3D broadband seismic
