Finite volume approximation for an immiscible two-phase flow in porous media with discontinuous capillary pressure
We consider an immiscible incompressible two-phase flow in a porous medium composed of two different rocks so that the capillary pressure field is discontinuous at the interface between the rocks. This leads us to apply a concept of multi-valued phase pressures and a notion of weak solution for the flow which have been introduced in [Cancès & Pierre, SIAM J. Math. Anal, 44(2):966–992, 2012]. We...
متن کاملStudy of Two Phase Fluid Flow in Water Wet Reservoir Rocks by Using X-Ray In situ Saturation Monitoring
Displacement of oil and water in porous media of reservoir rocks is described by relative permeability curves, which are important input data for reservoir performance simulation and drive mechanism studies. Many core studies, such as multiphase relative permeability, capillary pressure and saturation exponent determination, depend on the volume fractions of multiphase flui...
متن کاملCapillary pressure-saturation relations in porous media including the effect of wettability
In this work a functional relationship between capillary pressure and wetting phase saturation has been developed. Both the imbibition and drainage of a wetting phase liquid into a porous medium consisting of clean unconsolidated silica particles have been considered. In all, two bead packings, with average particle diameters of 120 #m and 360 #In, and three liquids--water, ethanol, and refrige...
متن کاملUnsteady State Relative Permeability and Capillary Pressure Estimation of Porous Media
To take capillary effect into account, a series of primary drainage experiments of water by a sample oil fluid have been studied. The experiments performed under different low flow rates on a horizontal glass type micromodel as a model of porous media. Based on conventional macroscopic flow equations, the relative permeabilities and capillary pressure are determined by parameter estimation tech...
متن کاملRelative permeability and capillary pressure functions of porous media as related to the displacement growth pattern
Visualization experiments of the unsteady immiscible displacement of a fluid by another are performed on glass-etched pore networks of well-controlled morphology by varying the fluid system and flow conditions. The measured transient responses of the fluid saturation and pressure drop across the porous medium are introduced into numerical solvers of the macroscopic two-phase flow equations to e...
