Compaction disequilibrium is by far the most abundant cause of developing hard geopressure in basins with very high rate of sedimentation. Precise prediction of both timings of source rock maturity and pore Previous HitpressureNext Hit development is essential for Previous HithydrocarbonNext Hit migration and entrapment modeling. Models build using stratigraphy-specific shale compaction curves (derived from a density log) in the PetroModTM 1-D and 3-D (IES, Germany) gives better results as compared to the widely used methods of single compaction curve for pore Previous HitpressureNext Hit prediction. The present study discusses the influence of pore-Previous HitpressureNext Hit development on migration and entrapment of Previous HithydrocarbonNext Hit both in normal and pressured reservoirs using above mentioned method. Furthermore, three-dimensional modeling, integrating pore Previous HitpressureNext Hit and source rock maturity enhances understanding of pore Previous HitpressureNext Hit distribution and its effect on Previous HithydrocarbonTop migration, both vertically and spatially.
