Pre-drill pore pressure prediction using seismic interval velocity and wireline log: Case studies for some wells in Cuu Long and Song Hong basins

Pore pressure can be obtained from seismic interval velocity by the to pore transform technique. In this paper, authors present Eaton experimental method calculate for some wellbores in Cuu Long and Song Hong basins, where complex processes of subsidence, burial, geological transformation, geothermal activity took place, causing abnormal zones.The results show that pressures calculated data are closely correlated with values measured well logging methods density drilling fluids. Therefore, using velocities values, identify predict zones effectively applied frontier areas improve safety, reduce risks while drilling.
