Table 8. Permeability and porosity values from cross-hole air-injection testing using borehole NDR-MF#2 for injection and borehole NDR-MF#1 for monitoring [Permeability values are x 10-12 meter squared; porosity is in parentheses; --, no data; FZ, fault zone; PFZ, partial fault zone, defined as a monitor interval located in the fault zone and footwall]
