Method for Determining the Geometry of an Area of a Reservoir
29 Apr 21
The application discloses a method for determining a geometry of an investigated area of a reservoir, wherein a volume of the investigated area is known, the method comprising: receiving a geological model of the soil in which said area is located, the geological model comprising a plurality of adjacent cells each having respective spatial coordinates and respective permeability values, and two wells being simulated in said geological model, determining a preferred flowing path between the two wells, the preferred flowing path being formed by a series of adjacent cells of the model, and determined based on the respective permeability values of the cells, evaluating a volume of the preferred flowing path and, if the volume of the preferred flowing path is lower than the volume of the investigated area, updating the preferred flowing path until its volume is superior or equal to the volume of the investigated area.

Reservoir Simulation Using An Adaptive Deflated Multiscale Solver
29 Jul 20
Systems, computer-readable media, and methods are described for performing a reservoir simulation by obtaining reservoir data, obtaining simulation parameters, determining partial differential equations based on the simulation parameters, and performing a timestep of the reservoir simulation based on the reservoir data and the partial differential equations by removing an effect of long coherent structures with high contrasts, such as fractures, faults, high and low permeability channels, or shale layers, from the partial differential equations to generate adapted partial differential equations, and performing an algebraic multiscale method on the adapted partial differential equations to generate an approximated solution.
