dc.description.abstractGrosmont is a large carbonate reservoir with 407 billion barrels of bitumen in place. However, it has not been commercially developed currently due to its extremely heterogeneous environment with various porosity types. A 3D heterogeneous carbonate model with high permeability conduits representing the Mclean pilot is built to investigate different recovery strategies including steam-based thermal schemes and solvent-aided methods. A vertical well CSS has severe steam override phenomenon and a SAGD process is extremely sensitive to its steam chamber which is hardly formed evenly in Grosmont. An improved hybrid SAGD in a staggered pattern that promotes lateral and downward sweep and retains more heat regardless of its steam chamber shape is presented and studied. Furthermore, a lower density and saturation temperature light solvent-aided process performs especially well in a heterogeneous carbonate reservoir with high permeability conduits. Parameter sensitivity effects are analyzed for each recovery strategy. The Brinkman-Stokes equations are tested in a 2D synthetic carbonate model, showing its possibility to describe the multi-physical flow in both free flow fractures and porous matrix. The application range and validity of Brinkman-Stokes multi-physical flow on karstified carbonates are discussed.en_US
