Abstract

Summary

We have generalized the streamline trajectory calculations and a novel global isoparametric coordinate system from hexahedron cells to other unstructured cells (prism, PEBI and tetrahedron). We have also developed a novel and flexible flux conservative double boundary layer construction which has sufficient degrees of freedom for flux consistency with the adjacent cells, even for complex faulted or embedded local grids. The solution has been implemented for both corner point and unstructured grids. In all cases the lowest order velocity model provides analytic solutions for trajectories and transit times. The construction at faults is completely determined by the flux across the non-neighbor connections, and supports both physical NNC’s, with a finite cell overlap area, and simulator NNC’s where no such area need exist. The results are demonstrated on simple type models, in near-well models, and in full field applications.
