  • Patent number: 8069018
    Abstract: A method for modeling fluid depletion in a reservoir is disclosed. A map is divided into cells. For each of the cells a value is stored that is based at least in part on a physical characteristic of the cell. At least one cell that contains a depletion location is identified along with a depletion amount corresponding to that location. An amount of walkers associated with the depletion location is determined. For each walker, a plurality of steps are calculated with each step to an adjacent cell. Each walker starts in the cell containing the depletion location associated with that walker. The visits of all the walkers are recorded by cell. The fluid depletion of each cell is then assessed based at least in part on the number of walker visits for each cell.

  • Patent number: 7996198
    Abstract: Methods, computer programs, and information handling systems for modeling one or more reservoirs are disclosed. The method uses one or more well logs, each for a well at a location and each including one or more Relative amount of Small Size Range of the Size Spectrum of Clastic Particles (RSSRSS) values versus depth. The method includes for one or more well logs: identifying one or more facies units based on RSSRSS values, determining a thickness of one or more facies units. The method includes determining a facies type of one or more facies units, categorizing one or more facies units, and connecting one or more facies units to create a reservoir model.

  • Patent number: 4991095
    Abstract: A process using a stored program processor for modeling a geologic volume which has inclined, stacked layers of sedimentary deposits. The process employs a model volume with layers of cells which are inclined and stacked analogous to the layers of sedimentary deposits. The cells are also arranged in vertical columns.

  • Patent number: 4821164
    Abstract: A process for modeling a bounded volume having a given geologic stratigraphic pattern, other than a volume having layers of uniform thickness parallel to mean sea level. The process comprises the steps of constructing a separate grid for each critical surface bounding said volume and constructing layers of cells according to the stratigraphic pattern.
