The tool analyses the behaviours and mechanisms of enhanced shale gas recovery (ESGR) by CO2 injection. This technique has the merits of both increasing the natural gas production to address the global energy crisis as well as simultaneously the geological storage of CO2 to reduce the anthropogenic greenhouse gas emissions. Thanks to the tool, the influence of pressure, temperature, moisture and gas type on isothermal adsorption and desorption of shale gas is analysed based on shale adsorption and desorption experiments. The adsorption and desorption abilities of CO2 and CH4 in shale are compared as well as the ultimate recovery of depletion production and CO2 injection production.
Description
The GADIS determines the adsorption isotherm for a combination of adsorbate (e.g. methane, CO2,) and adsorbent (coal, shale etc.). In other words, the system evaluates at equilibrium, the maximum volume of gas adsorbed onto an adsorbent, at a specific temperature and pressure. The latter is achieved by means of the isothermal volumetric method in which the pressures and volumes of a reference and test cell held at constant temperature, are continuously monitored. The apparatus is fully automated, allowing computer-controlled gas injection, pressure monitoring and data acquisition. Up to four testing chambers can be integrated into the system to allow simultaneous and independent testing.
