In this study, we demonstrate the use of multi-scenario 3D AVO feasibility volumes generated from burial history and calibrated rock physics models, to assess expected rock properties and AVO signatures, at any given (pseudo-well) location within the area of a given merged multi-survey seismic velocity volume. The AVO feasibility volumes/maps can be utilized in quantitative interpretation and prospect evaluation by comparing the feasibility modeling with real AVO data. A key aspect of the methodology is to create spatially varying sandstone and shale depth trends constrained by burial history and depositional trends. Uncertainties in the AVO feasibility modeling are predominantly associated with varying temperature gradients, grain size, clay content and net-to-gross. Multi-scenario modelling can be done to evaluate these uncertainties. The future focus will be to combine feasibility modelling with AVO classification and prediction.
