Sandstone 10-5 to 10-9 10-6 0.05 to 0.15 0.10
Shale 10-8 to 10-12 10-9 0.005 to 0.05 0.01

1vertical saturated conductivity is considered to be one-tenth the value of horizontal saturated conductivity.
2Specific yield is expressed here as a fraction. It is often reported as a percentage in the literature.
