In a recent paper, Yamada et al . (2005) derived an expression to calculate hydraulic permeability under non‐Darcy flow conditions using the packer test; their results were obtained via numerical integration of the derived expression. Their findings are extended by providing a closed‐form solution to the problem, and its dependence upon key parameters is illustrated. Copyright © 2008 John Wiley & Sons, Ltd.
