In this paper, a multi-point flux mixed-finite-element decoupled method was considered for the compressible miscible displacement problem. For problem, fully discrete backward Euler scheme proposed, in which velocity and pressure equations were by MFE using BDM1 elements combined with trapezoidal quadrature rule. The concentration equation handled standard FE method. error analysis velocity, pr...

The paper investigates the linear growth of mixing zone, in a pessimistic scenario, during polymer slug injection into water reservoir. velocities front and boundaries zone are numerically analytically studied as key parameters characterizing miscible displacement. Using two different numerical methods (finite volumes finite elements), impact size, reservoir dimensions, Peclet number, viscosity...

We establish the existence of a solution to a non-linearly coupled elliptic-parabolic system of PDEs describing the single-phase, miscible displacement of one incompressible fluid by another in a porous medium. We consider a velocity-dependent diffusion-dispersion tensor and model the action of injection and production wells by measures on the domain. We obtain the solution by passing to the li...

Carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. Depending on the operating pressure, the process might be miscible or immiscible. Minimum miscibility pressure (MMP) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. The miscibility condition is determine...
