Composite VNT permeability obtained from PEST/FEHM numerical models in this study (116 measurements total). VNT-a is the shallowest unit. Depth increases from VNT-a to VNT-10. The line, whiskers and black open circles of the box plots are the median, 95% confidence interval and outliers of the packer test permeability distribution. Circle and error bars for the cavity pressurization test represent the calibrated permeability and 95% confidence interval, respectively. Error bars that extend beyond the range of PEST permeability estimates are labeled in red, indicating they are relatively insensitive to the calibration process.
