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
