Underground Storage of Natural Gas in Hydrate State: Numerical Experiment
Abstract The paper is devoted to simulation of the initial stage of natural gas hydrate underground storage: gas injection into aquifer just below permafrost rocks. It is based on the mathematical model of multiphase non-isothermal real gas and water flow in porous media. The model takes into accoun...
