Characterization and Modeling of Fractured Reservoirs – Flow Simulation

B036 CHARACTERIZATION AND MODELING OF FRACTURED RESERVOIRS – FLOW SIMULATION Abstract 1 Flow simulation of fractured reservoirs has traditionally been performed using dual porosity models. These are typically characterized by a shape factor σ and a matrix material z-dimension dz. Rock characteristics such as σ and dz will usually vary over the volume of rock included in a reservoir simulator grid block. Assuming a single value per grid block may represent a significant oversimplification particularly when a process such as gravity drainage depends sensitively on the values. Fracture characterization can be done using simple models – such as the Warren
