Research of deep hydrocarbon potential is an actual purpose now, which is often connected with the overpressures. Nowadays many deep fields were opened in different regions: from Mexican bay to the North seas. On the other hand, there are a lot of dangerous situations during drilling every year. These situations vary by degree of consequences and can cost many financial and ecological expenses. However, overpressures are not only technical risks, they also have geological risks. This article represents how connection of pressure and seismic velocity can lead to mistakes in structural geological maps. So this distortion causes wrong estimation of layers depth, incorrect estimation of resources and objects selection. Nevertheless, pore pressure prediction can minimize all these indeterminacies and get a correct structural map with the correct resource estimation.
