Classification: CPC G  E | IPC E  G

Claim 19:
20. One or more computer-readable storage media comprising computer-executable instructions to instruct a computer, the instructions comprising instructions to:
access a depogrid generated via gridding of a structural model in a depositional space and transforming the gridded structural model to a geological space via an inverse mapping wherein the structural model represents structural features in a subterranean environment based at least in part on data acquired via at least one sensor;
determine local u, v and w axes for a plurality of cells in the depogrid via volumetric centroids and vertices of each of the plurality of cells as represented by coordinates in a depositional space coordinate system (u, v, w) and by coordinates in a physical coordinate system (x, y, z);
orthonormalize the local u, v and w axes for the plurality of cells to generate orthonormalized local u, v and w axes for the plurality of cells, wherein an increased local amount of orthonormalization indicates a decreased local quality due to locally inconsistent interpretation of one or more of the structural features represented in the structural model;
define directional geological grid properties based at least in part on the orthonormalized local u, v and w axes, wherein the directional geological grid properties comprise a tensor permeability property; and
simulate fluid dynamics of the subterranean environment via a simulator to generate simulation results based at least in part on at least a portion of the directional geological grid properties as assigned to the depogrid.
