Recently, new seismic products for quantifying uncertainties associated with delivered seismic products have emerged. It is therefore important for reservoir risk analysis to pass the uncertainties along with the data delivered. In an exploration context, identifying potential traps by combining structural and sedimentology information is a challenging process due to the lack of well data to validate the potential presence of reservoir in the lead. In this paper, we illustrate the integration of tomography velocity uncertainties in a resource evaluation workflow and demonstrate the impact on gross rock volume (GRV) distributions for the ranking of potential prospects.
