Overview Constrain gradient-based solution to a  minimum of spatial information Deal with the issue of reservoir flow  simulation Introduce upscaling Make calculation of sensitivity coefficient possible  on large grids

Method: overview match 1 2 3 4 5 1. Generate a high resolution reservoir model constrained to  static reservoir data 2. Upscale to a coarsened model to make flow simulation feasible 3. Use gradient techniques to perturb the model, but accounting  for spatial variation 4. Downscale the model back to a high-resolution model to re- introduce 5. Do non-uniform upscaling for fine flow simulation
