One-Dimensional Productivity Assessment for On-Field Methane Hydrate Production Using CO2/N-2 Mixture Gas
The direct recovery of methane from gas hydrate-bearing sediments is demonstrated, where a gaseous mixture of CO2+N-2 is used to trigger a replacement reaction in complex phase surroundings. A one-dimensional high-pressure reactor (8 m) was designed to test the actual aspects of the replacement reac...

The direct recovery of methane from gas hydrate-bearing sediments is demonstrated, where a gaseous mixture of CO2+N-2 is used to trigger a replacement reaction in complex phase surroundings. A one-dimensional high-pressure reactor (8 m) was designed to test the actual aspects of the replacement reaction occurring in natural gas hydrate (NGH) reservoir conditions. NGH can be converted into CO2 hydrate by a replacement mechanism, which serves double duty as a means of both sustainable energy source extraction and greenhouse gas sequestration. The replacement efficiency controlling totally recovered CH4 amount is inversely proportional to CO2+N-2 injection rate which directly affecting solid - gas contact time. Qualitative/quantitative analysis on compositional profiles at each port reveals that the length more than 5.6 m is required to show noticeable recovery rate for NGH production. These outcomes are expected to establish the optimized key process variables for near future field production tests. |
