Permeability in geology
Web3-D variability in fault permeability. The permeability along a fault can be highly variable for the following reasons: The dimensions of fault cores and damaged zones will vary along a fault, depending on differences in mechanical strength (e.g., cemented sandstone versus shale), the magnitude of the stresses, and fracture plane asperities. WebNov 1, 1997 · Our test results show three important results: (1) permeability decays exponentially with P^, (2) permeability of the damaged zone is 10-1000 times greater than samples from the protolith or fault core, and permeability in the damaged zone samples drops off more slowly with Pc than do samples from the protolith or fault core, and (3) …
