Patents by Inventor Stéphane VIGNAU

Stéphane VIGNAU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10976468
    Abstract: Disclosed is a method of determining front propagation within a subsurface volume such as a reservoir. The subsurface volume includes a plurality of cells and at least one geological fault. The method includes performing a fast marching algorithm so as to determine the front propagation in terms of the time of arrival of the front at a particular cell from one or more neighboring cells which make up the neighborhood of the particular cell. For each faulted cell that is adjacent a geological fault, the neighborhood of the faulted cell is defined as including only its geometric neighbors, where the geometric neighbors are those cells that are in contact with the faulted cell in a geometric sense, regardless of stratification.
    Type: Grant

  • Patent number: 10422926
    Abstract: Disclosed is a method of determining front propagation within a subsurface volume such as a reservoir. The subsurface comprises a plurality of cells and at least one geological fault (210). The method comprises performing a fast marching algorithm so as to determine said front propagation in terms of the time of arrival of the front at a particular cell from one or more neighboring cells which make up the neighborhood of said particular cell. For each faulted cell (C) that is adjacent a geological fault, the neighborhood of the faulted cell is defined as comprising only its geometric neighbors (NS, NG cells and NG cells) where the geometric neighbors are those cells that are in contact with the faulted cell in a geometric sense, regardless of stratification.
