Reservoir Characterization and an Integrated Approach of Reservoir Modeling for Miano Gas Field, Middle Indus Basin

The hydrocarbon-bearing formation of Miano gas field belongs to the Early Cretaceous and it is bounded by two shale intervals, which are considered as maximum flooding surfaces (MFS). interval includes reservoir units: a tight its overlying conventional reservoir. Core samples, borehole logs, well production performance revealed that reservoirs present reversed trends in quality through without obvious barriers. average volume changes from 24.3% 12.2% permeability 32.65 mD 0.02 south north. However, effective porosity overlaying increases 20% 26% 10 300 mD. lead challenges forecast development proposals Therefore, characterization predictive model essential for further exploitation field. geological genesis analysis integrating cores, three-dimensional (3D) seismic data reveals producing tidal-influenced shore facies deposition with intergranular pore space reduced mineral cementation during burial diagenesis, while fluvial-influenced deltaic abundant, well-connected macropores, leads better quality. A containing both constructed considering nature understanding, accuracy confirmed surveillance activities simulation model. study will be critical hydrocarbon
