HOWELL 3 1 Heriot-Watt Institute of Petroleum Engineering Edinburgh EH3 9NX UK Summary We present a workflow for rapid generation of appropriate relative permeability and capillary pressure curves for use in reservoir simulation models of a shallow marine environment. The method employed a two-level upscaling approach focusing first on the facies scale and then on the simulation grid-cell scale. To simplify the upscaling process we adopted a
