Abstract：A new method for pore pressure prediction of sand-shale formations using seismic interval velocity is proposed. Some application results of the method are also shown. The single point algorithm is used based on the effective stress approach. The vertical effective stress is calculated by a four-parameter compressional velocity model that describes the relationship between sonic velocity and vertical effective stress. The method is simple in practical operation without need of normal trend. It is mainly used in new prospecting area with rare related data. The applications in various basins show that the predictions with the proposed method can be useful for drilling safety and efficiency，especially for Cenozoic shale-sand formations.
