Abstract In natural gas engineering, the numerical simulation plays a significant role in the exploration, production and optimization of natural gas
reservoir. However, numerical simulations of compressible gas flow in porous media are always expensive due to the gas compressibility and nonlinear
properties. To save the computational cost, in this work we present a multigrid
coupled discrete empirical interpolation method (MG-DEIM) to speedup the simulation of compressible gas porous flow. In this MG-DEIM framework, the core idea is that the multigrid method based on the full approximate scheme
(FAS) is used to solve the flow equation (a pressure equation); for the… More >
