In the present contribution, we construct a virtual element (VE) discretization for problem of miscible displacement one incompressible fluid by another, described time-dependent coupled system nonlinear partial differential equations. Our work represents first study to investigate premises methods (VEM) complex flow problems. We combine VEM with time stepping scheme and develop complete theore...

Miscible gas injection, as an Enhanced Oil Recovery (EOR) method, can improve the recovery factor by swelling the residual oil and phasing out the interfacial tension [1]. However, the sweep efficiency of miscible gas injection is not satisfactory because of conformance problems, such as viscous fingering, channelling and gravity override [2]. Foam can solve the problems associated with gas inj...

for technical and economic success of miscible gas injection projects, an accurate laboratory measurement of minimum miscibility pressure (mmp) at reservoir conditions is essential. on the other hand, compositional reservoir simulator is a useful tool in gas injection studies and prediction of mmp. the main goal of this paper is to describe a procedure to generate a three phase sequential type ...

The displacement of a more viscous fluid by a miscible, less viscous one of lower density in a horizontal capillary tube is studied by means of Stokes flow simulations. Both axisymmetric and three-dimensional simulations are conducted at Péclet numbers up to 104, in order to resolve discrepancies between earlier simulations by [C.Y. Chen, E. Meiburg, Miscible displacements in capillary tubes. P...

Effective numerical simulation of many EOR problems requires very accurate approximation of the Darcy velocities of the respective fluids. In this paper we describe a new method for the accurate determination of the Darcy velocity of the total fluid in the miscible displacement of one incompressible fluid by another in a porous medium. The new mixed finite-element procedure solves for both the ...
