The experimental data of replacement of methane with carbon dioxide in gas hydrate using various intensifiers of the substitution process are represented in this article. When nitrogen was used as the gas of the intensifier of the substitution process, a growth of 15% in the volume of carbon dioxide substituted for methane was revealed in a 30/70% ratio for the same period of time and the same experimental conditions. When atmospheric air was used as a gas intensifier for the substitution process, as a cheaper alternative component, a 36% increase was detected in the volume of carbon dioxide that replaced methane at a ratio for the same period of time and the same experimental conditions. When applying thermal stimulation and substitution using preheated carbon dioxide, the growth was 44% and 52%, respectively.
