The educational gasperm instrument is dedicated to measure permeability to gas (air, nitrogen,..) of plug sized core samples at room conditions and reservoir overburden pressure using the steady state method. The instrument is designed for the injection of gas through the test sample at various conditions of pressure and flow rates. The injection pressure at the core face is measured using a pressure transducer and the gas flow rate is measured using a precision mass flow meter. An excel spreadsheet calculation template allows for calculation of gas permeability.
