Abstract

In the course of experimental study, an assessment was made of the methane recovery from hydrate-bearing sandy reservoirs by flue gas injection. The experiments used a flue gas consisting of 14.6 mole% carbon dioxide (CO2) and 85.4 mole% % of nitrogen (N2) which is similar in composition of combustion products of coal-fired power plants. Experiments were carried out in the temperature range from +0.2 to -12 C at a pressure around 5 MPa, to determine optimal conditions for methane recovery from subpermafrost and intrapermafrost hydrate-saturated reservoirs. The results show that, despite the differences in recovery kinetics of natural gas from hydrate phase under different temperature conditions (the high rate of decomposition of methane hydrate was observed at a temperatures above 0 oC than at temperatures below 0 oC), the total methane recovery rate was practically the same. Thus, it has been shown that the method of flue gas injection can be used for methane recovery from intrapermafrost gas hydrates.
