Pressure prediction in sedimentary basins is relevant for mapping and/or extending a productive reservoir characterized by a low-pressure zone, which is an important principle in hydrocarbon prospecting. A major part of the efforts in this work was to structure a seismic-stratigraphic framework for modeling and imaging part of the Jequitinhonha basin, that can be used to evaluate its characteristics and potential for producing oil and gas. In practice, the main application of the method is to

... p a reservoir, as well as its lateral and vertical extensions. The required information for modeling is the distributions of the seismic velocities V P and V S and density ρ. These pieces of information can be based on velocity analysis, seismic-stratigraphic interpretations of migrated data, petrophysical data, and empirical models that can provide a relationship between velocities, density, and porosity, which can also be incorporated. Our proposed model admits vertical gravity loading as the stress-deformation generator on the geological formations, but it does not take into account the effects of curvatures, faulting, diagenesis, and lateral tectonic events as loading mechanisms. The presented robust pressure prediction method was applied to a 3D interpolated model to map the low-pressure zones (possible reservoir) capped by a high-pressure zone, as a significant petroleum geology application.
