Abstract

The production of methane (CH4) from natural gas hydrates (NGH) through the injection of carbon dioxide (CO2) is regarded as a sustainable method for both energy recovery and carbon sequestration. However, its viability is hampered due to the low CH4 recovery rates imposed by the mass transfer constraints during the exchange process. This research has been devoted to implementing nuclear magnetic resonance (NMR) methods to non-invasively investigate the CH4/CO2 exchange reaction in hydrate-bearing porous media. The design of a novel NMR-compatible cell is reported, which facilitated the monitoring of hydrate formation/dissociation processes and controlled CH4 replacement reactions by injected CO2
