Injections of pressurized carbon dioxide in natural gas hydrates have attracted a number of attentions because it can simultaneously serve as a means of methane gas exploitation and greenhouse gas sequestration. It has been found that gas recovery could be significantly enhanced by adding small molecules gases such as nitrogen or hydrogen into injected gas mixture. In this work, the Raman spectroscopy, gas chromatography and charge coupled device were used to study the effect of injecting small molecule gases on the methane hydrate decomposition.

Keywords Gas hydrates exploitation, decomposition, nitrogen, hydrogen.
