The sharp decline in oil prices is pushing exploration and production companies to revise future investment plans and ensure that investment decisions come with positive returns. Reservoir modeling is a key tool in the evaluations, as it explores different development scenarios to optimize field performance and gain the most value out of the reservoir. Traditional reservoir modeling, however, relies on a single or small number of scenarios (base, high and low cases) and introduces deterministic prediction profiles for future field performance that don’t fit with modern reservoir management guidelines. Such a modeling approach also fails to integrate the impact of uncertainties at the different reservoir modeling stages - from seismic interpretation to dynamic simulation. Using an integrated reservoir modeling and reservoir engineering workflow, the Big Loop and its ensemble statistics-based approach can generate crucial information to reduce risk and support decision making - in determining reservoir uncertainties and their ranges, planning future field development, and guiding well placement using multiple history match models.
