Abstract. In the paper the numerical solutions of the forward and inverse fluid dynamic problems for geological time scale have been considered in connection to excess pore pressure (EPP) prediction. The set of the most sensitive to the EPP evolution model parameters has been introduced. The forward problem of the fluid dynamics describes the compaction, HC-saturation and overpressure evolution vs. time and depth. The corresponding real well data set is used as an input for the inversion routine. The 1.5D reduction of the 3D inverse problem is developed. Such approach allows to achieve a more unique and stable inverse problem solution in reasonable computing time. The particular forward modelings for a homogeneous and layered medium are discussed. Applications of the approach to the EPP prediction are demonstrated on the practical examples.
