CARBON DIOXIDE GAS HYDRATES ACCUMULATION IN FREEZING AND FROZEN SEDIMENTS
The paper presents results of the experimental research on the process of CO2 gas hydrates formation in the porous media of sediments under positive and negative temperatures. The subject of research were sediment samples of various compositions including those selected in the permafrost area. The r...
