Deterministic and Probabilistic Volumetric Evaluations of an Iranian Field in an Exploration Reservoir

Volumetric evaluation of exploration reservoirs is one of the most significant and key steps during field development. In this study, volumetric estimation was performed on the target formation and uncertainty analysis was done in two approaches while considering the variation of parameters such as contact, NTG, porosity, Sw and Bo. One should note that, the map-based approach is more accurate than considering a single average value. Sensitivity analysis was also done in order to determine the most effective parameter on the estimated oil in place. The Tornado diagram demonstrates that contact is the most effective parameter in volume calculation.
