  • Right sizing reservoir models
    Patent number: 8350851
    Abstract: Disclosed herein are improved systems and methods for right sizing grid models for performing, for example, reservoir simulations. Implementations in accordance with the present disclosure may begin with a relatively fine scale grid model. Successive coarsening and resampling operations may be repeated until one or more characteristics of the coarsened grid model begin to unacceptably diverge from those of the fine scale model. Similarly, successive coarsening and upscaling operations may be performed until one or more characteristics of the coarsened grid model begin to unacceptably diverge from those of the previously-coarsened grid model. The resulting coarsened grid model may be suitably sized for reservoir simulations.
    Type: Grant
    Filed: March 5, 2009
    Date of Patent: January 8, 2013
    Assignee: Schlumberger Technology Corporation

  • Coarsening and splitting techniques
    Patent number: 8339396
    Abstract: Disclosed herein are improved coarsening and splitting techniques for preparing grids for performing simulations. In some implementations, methods in accordance with the present disclosure may include providing a grid having a plurality of grid pillars; and performing one or more splitting operations on at least a portion of the grid to increase a grid density within the portion of the grid, the plurality of grid pillars within the portion of the grid being forced to remain fixed in position during the one or more splitting operations.
