Figure F8. Permeability of Samples 174A-1073A-8H-1, 23-26 cm, and 71X-1, 9-14 cm, referenced to porosity. Porosity is approximated based on the stress state of the permeability experiment and the porosity calculations on Samples 174A-1073A-8H-1, 17-22 cm, and 71X-1, 2-8 cm. Data are provided in Table T9.
