Modelling of process of displacement of methane from gas hydrate reservoir at dioxide carbon injection

Abstract The paper presents a mathematical model for describing the process of displacing methane with carbon dioxide from a reservoir saturated with methane and its hydrate. For gas substitution kinetics, a scheme has been proposed in which the intensity of the process is defined by the diffusion o...

Description
Summary:Abstract The paper presents a mathematical model for describing the process of displacing methane with carbon dioxide from a reservoir saturated with methane and its hydrate. For gas substitution kinetics, a scheme has been proposed in which the intensity of the process is defined by the diffusion of carbon dioxide through the hydrate layer formed between the gas mixture flow and methane hydrate. The numerical research of influence of main parameters on dynamics of process is conducted. Influence of coefficient of diffusion mixing of the gas mixture and permeability for the time of complete gas-replacement in reservoir is studied.
