Summary:
Static connectivity measures have been proposed for quick evaluation of reservoir performance to provide a potentially important link between the reservoir characterization and the simulation studies. These measures are easy in concept and inexpensive in execution, and create an important, intermediate level in the assessment of reservoir productivity. This paper proposes a framework for static connectivity analysis in reservoirs that use water flooding technique and pressure propagation fronts as it used in well testing. The software uses a fast marching method and a shortest path algorithm that both are sensitive to geological heterogeneities which can give some insights into finding the connective geobodies. An illustrative example is shown to describe the software interface and to present a simple but systematic connectivity analysis scenario. The distinct tasks contained in a typical reservoir development workflow may be benefited from the addition of connectivity analysis, such as the assessment of optimum well placements for injection-production wells and the evaluation of features of stratigraphic architectures that affect the recovery. The proposed tool is towards providing a geoengineering approach to use the geological knowledge for proposing better production scenarios.
