Vavrychuk P. Mathematical modeling and numerical analysis of two-phase filtration of gas and liquid in a porous medium

The thesis solved urgent scientific and technical problem analytical and numerical modeling of the process gas substitutability water to prevent flooding wells and determine the available amount of gas in the water. For the first time, the system model of gas flow in an underground gas storage was developed that describes the filtration, diffusion, convective and gasdynamic processes in the interconnection, which made it possible to develop an approach for estimating the amount of diffused gas in water during operation of an underground gas storage and to investigate the velocity of the gas-water contact from to prevent flooding of the well.
