| Abstract: A one-dimensional isothermal transient two-phase flow model of gas and liquid in a low-permeability medium has been developed from the general mass and momentum balances.^The characteristic roots of the governing differential equations are real and distinct.^Therefore, solution of the flow equations may be attempted by a stable initial-value finite-difference scheme.^A numerical solution was obtained using the method of lines.^Calculated two-phase flow parameters are consistent with expected flow behavior and reflect the sensitivity of fluid flow to porosity, gas and liquid permeability, and capillary pressure in a tight sands porous medium.^Calculated gas flow rates compare well with experimental data obtained at the Institute of Gas Technology (IGT) for low-permeability sandstone. |
