Klinkenberg permeability correction method
WebJun 19, 2024 · The Klinkenberg slippage theory has widely been used to obtain gas permeability in low-permeability porous media. However, recent research shows that there is a deviation from the Klinkenberg slippage theory for tight reservoir cores under low-pressure conditions. In this research, a new experimental device was designed to carry … WebOct 1, 1972 · Abstract. A simple, unsteady-state apparatus and appropriate theory have been developed for measuring the Klinkenberg permeability, Klinkenberg slip factor, and Forchheimer turbulence factor of core plugs. The technique is last and accurate and bas replaced nearly all steady-state gas permeability determinations made in our laboratory. …
