WebOct 5, 2015 · The accurate measurement of the shale permeability is challenging because it is small, around 10-21 m2 (nanoDarcies). The challenge presents itself in both experimental and theoretical investigations. For instance, constant pressure steady-state flow measurement is not used for shale since it requires considerable time.
