The sample is saturated with cycle gas, maintained for an appropriate soak period and then reduced to expected well drawdown pressure. Effluent gas is produced through a trap to condense hydrocarbons for later measurement. The re-pressurization and depletion is repeated for subsequent cycles. The experimental conditions can be modified to simulate the appropriate “Huff n’ Puff” process. The system is fully customizable to accommodate your sample dimensions, pressure and temperature requirements.
