Application of a New Upscaling Technique to a Miscible Gas Injection Field Study

D11 APPLICATION OF A NEW UPSCALING TECHNIQUE TO A MISCIBLE GAS INJECTION FIELD STUDY Abstract 1 A novel miscible upscaling technique incorporating the use of effective flux boundary conditions and an extended Todd & Longstaff treatment of upscaled relative permeabilities was recently developed and successfully applied to synthetic 2D permeability fields. In this work we extend the overall upscaling procedure to nonuniform 3D grids and apply it to a miscible gas injection field study. A near-well upscaling procedure is also incorporated into the methodology. It is shown that the original fine grid model must be refined areally to achieve numerical
