Steady State Gas Perma meter
GPS01/ 2018 accurately determines the permeability to gas of plug-sized core samples at ambient temperature and moderate confining pressure by steady state method. Implementing a constant flow rate across the sample. Gas can be injected over a wide range of pressures and flow rates. The core inlet pressure is continuously monitored by an inline differential pressure transducer while the gas flow rate is reported by a high-grade mass flow meter.
A precision metering valve for back-pressure control permits a better Klinkenberg interpolation. The apparatus can be used with both consolidated and unconsolidated core samples ( prepared in metal or plastic sleeves with retaining screens at the ends). A dedicated software and data handling station provide live calibration and parameter measurement.
