Calibrated permeability from the cavity pressurization test (top left panel; values from Table 2, S2). Four VNT units contain GS samplers: VNT1 (GS-2), VNT5 (GS-1 and 3), VNT 8 (GS-5) and VNTa (GS-4, 6 and 8). Pumping rates into the cavity during the test are shown in Figure S2. Simulated (dashed lines) versus observed (solid lines) pressure signals at GS samplers and cavity during the cavity pressurization test from PEST calibration. The pressure observations used as PEST calibration targets are shown as black stars.
