Abstract: Seismic data commonly provides insight into subsurface reservoirs. However, only seismic is not capable to completely evaluate reservoir pore fluid heterogeneities. Therefore, an integrated approach of seismic interpretation, petrophysical analysis and Gassmann fluid substitution is used in Meyal area, for its reservoir depiction and field development. The results of seismic analysis reveal that the study area is in compressional regime and thrust bounded pop-up structure makes it appropriate for hydrocarbon accumulation. A new lead is identified that could be probable hydrocarbon potential zone. Petrophysical investigation depicts that the zone is saturated with hydrocarbon and hold suitable effective porosity. In addition, fluid substitution in desired zone reflects variations in elastic properties (P, S-wave velocity and density) when substituted with brine. The maximum variations are perceived at maximum saturation of brine. This approach can be confidently applied to quantify reservoir potential in any sedimentary basin of the world.
