One of these methods, the multiscale finite-volume (MsFV) method is well studied for 2D Cartesian grids, but has not been implemented for stratigraphic and unstructured grids with faults in 3D. With reservoirs and other geological structures spanning several kilometers, running simulations...

These first results are encouraging and need further investigation. The method is general, and can account for other dynamic...

Saturations and mole fractions will not be updated during this step. The solution of the first step provides the boundary influx for the windows and the pressure...

... Abstract The streamline method has proved to be extremely successful for reservoir simulation 1 . For a Cartesian grid the standard five point (7 in 3-D) discrete pressure equation is employed within the IMPES streamline method. The accuracy of the velocity field plays a critical role...

... Cartesian grid (10x10x4) was run using the nine-point option. A five-point simulation was also made and was found to give result significantly different from the nine-point simulation in terms of the two GOR acceptance criteria set out in the project. This is likely caused by the well-known grid...
