Study on the factors affecting the sealing performance and mechanical stability of CO2 hydrate cap during gas production from methane hydrate

An innovative idea of “reservoir reformation” was proposed earlier and verified to be feasible for enhancing methane gas recovery efficiency and CO2 sequestration by constructing an artificial impermeable CO2 hydrate cap between the methane hydrate reservoir and overburden. However, the effects of different factors on the sealing performance and mechanical stability of the CO2 hydrate cap need to be further clarified for the optimization of this...
