%X The formation pressure prediction with well\|constrained seismic inversion data can be applied to abnormal porosity formations in which abnormal pressures derive from disequilibrium compaction action. Firstly, identify the mechanisms of abnormal pressure and make sure that it is related to disequilibrium. Secondly, map the normal trend distribution of sonic\|velocity and velocity on surface using sonic\|log data. Both of them are the important parameters in this method. Thirdly, extract bed velocity body with well\|constrained seismic inversion. After that, formation pressure can be calculated by balance\|depth equation.
