TL;DR: In this paper, a semi-continuous CO2/H2 injection-production model was proposed, in which continuous CO2 injection process is interrupted periodically by stopping injection and production operations for letting injected gas diffuse sufficiently, delaying its breakthrough and increasing its effective sweep region.

TL;DR: In this article, a new numerical simulator was developed from the widely used CH4 hydrate simulator TOUGH++HYDRATE to realize the simulation of hydrate exploitation by CO2/N2-CH4 replacement.

TL;DR: In this paper, the authors provided an exergy analysis method to evaluate the economic efficiency of natural gas hydrates exploitation process by brine stimulation combined depressurization method, and the input data including cumulative volume of gas production, mass of water production and gas-to-water ratio was obtained by the numerical simulation of TOUGH+−HYDRATE.

TL;DR: In this paper, the spatial difference of hydrate dissociation by depressurization was investigated in an L-shape hydrate simulator to enhance the exploitation efficiency of natural gas hydrates.

TL;DR: In this article, 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 new technology.
