The authors propose an analytical method to calculate effective block permeabilities as a full tensor based on the geometry, block size, full local tensorial permeabilities, and the geology within the block. The method was validated with a finite-element numerical simulator and was applied to a simulation of flow through an outcrop of the eolian Page sandstone. Results show that the relative positions of the main geologic features and the ratio between the grain-flow and wind-ripple permeabilities are more important than bounding surfaces and dispersion in determining flow behavior.
