چکیده
three-phase (e.g., water, oil, and gas) flow in porous media, includcomplex than the corresponding two-phase curves. It is ing phase, global, and pseudo-global pressure-saturation formulathe complexity of these three-phase curves that complitions, are discussed in this paper. Comparisons of these differential cates the derivation of the global pressure-saturation form formulations are theoretically and numerically presented for the for the former case. In the two-phase flow, the governing first time. It is shown that the global pressure-saturation formulation equations can be written in terms of a global pressure and is the most efficient one from the computational point of view in

متن کاملComparison of Binomial and Power Equations in Radial Non-Darcy Flows in Coarse Porous Media
Analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. Darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. Non-linear equations are classified into power and binomial equations. Binomial equation is more accurate in a wide range of velocit...
متن کاملApplication of Homotopy Perturbation Method to Nonlinear Equations Describing Cocurrent and Countercurrent Imbibition in Fractured Porous Media
In oil industry, spontaneous imbibition is an important phenomenon in recovery from fractured reservoirs which can be defined as spontaneous uptake of a wetting fluid into a porous solid. Spontaneous imbibition involves both cocurrent and countercurrent flows. When a matrix block is partially covered by water, oil recovery is dominated by cocurrent imbibition i.e. the production of non wettin...
