Fractured reservoirs are some of the most productive oil reserves in the world, but deviations in the geological formations surrounding the reservoir increase the time and cost of oil extraction. Oil and gas companies rely on advanced imaging techniques and computer generated models to determine how oil is flowing and manage surface parameters to get the most out of the reservoir. Fractured reservoir simulation, however, requires representing complex, irregular domains and complicated fracture networks that traditional simulation methods cannot handle.

The Fractured Reservoir Simulator uses control volume finite element formulations to enable field-wide reservoir simulation of complex domains and spatial fracture characterization. The simulator directly incorporates characterization of faults and fractures. Flux-based upstream weighting is employed to ensure flux continuity and solution stability. This enhances simulations by allowing for the combination of different physical and discretization models to cover a wider array of fractured reservoir characteristics.
