To avoid the risks of drilling in areas with high pore pressure and planning wells, it is necessary to estimate the pore pressure. The purpose of this study is to estimate the pore pressure using well log and seismic data and compare their performance. In the well logging method, the pore pressure is estimated from the values measured by the resistivity, sonic and velocity logs according to the relationships presented by Eaton (1975). Then, using Bowers method (1995), the overburden pressure was calculated using density log, and then using the relationship between velocity and effective stress, the effective stress was estimated. Subsequently, using the Terzaghi relationship, the pore pressure was estimated. In the next step, using 3D seismic data and employing Eton and Bowers methods, the pore pressure was estimated as a 3D cube. The results of this study show that the Eaton velocity method with an error of 9.7% is most consistent with the measured data at the well site and provides the most appropriate spatial pressure distribution at all depths.
