Effective Model of Two-phase Flow in a Porous Medium Made of Different Rock Types
نویسندگان
چکیده
We consider the behavior of immiscible and incompressible two-phase ows in a porous medium made of several rock types. Each rock type, is deened by one porosity, one absolute rock permeability ten-sor, two relative permeability curves and one capillary pressure curve. Using two-scale convergence, we get an homogenized model which governs the global behavior of the ow. In this model, macroscopic equations are generally coupled with local equations; but under some assumptions , these two problems can be decoupled.

Numerical Evaluation of Hydraulic Fracturing Pressure in a Two-Phase Porous Medium
Hydraulic fracturing is a phenomenon in which cracks propagate through the porous medium due to high pore fluid pressure. Hydraulic fracturing appears in different engineering disciplines either as a destructive phenomenon or as a useful technique. Modeling of this phenomenon in isothermal condition requires analysis of soil deformation, crack and pore fluid pressure interactions. In this paper...
متن کاملAn Existence Result for Multidimensional Immiscible Two-Phase Flows with Discontinuous Capillary Pressure Field
We consider the system of equations governing an incompressible immiscible two-phase flow within an heterogeneous porous medium made of two different rock types. Since the capillary pressure function depends on the rock type, the capillary pressure field might be discontinuous at the interface between the rocks. We introduce multivalued phase pressures to give a sense to the transmission condit...
متن کاملAnalytical Investigation of Forced Convection in Thermally Developed Region of a Channel Partially Filled with an Asymmetric Porous Material- LTNE Model
In present work forced convection flow in a channel partly filled with a porous media under asymmetric heat flux boundary condition has been investigated. The porous material is distributed on the one wall. Darcy–Brinkman and LTNE model have been assumed in order to solve momentum and energy equations, respectively. Fully developed conditions are considered in order to solve velocity and the te...
متن کاملExperimental Study of Nanofluids Flow in a Micromodel as Porous Medium
For better understanding the effect of nanofluid flow in a porous medium, a set of experiments were conducted on a horizontal glass micromodel for Al2O3-water nanofluids. To characterize the flow of nanofluids the same experiment was done by pure water. The glass micromodel was constructed by a photolithography techniqu...
متن کاملLab and Field Scale Modeling of Near Miscible CO2 Injection in Different Porous Mediums
The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...
