Displacement of oil by water in porous media and determination of flowing laws
The petrophysical data required to predict the behaviour of an oil reservoir submitted to water injection were obtained from porous-medium samples, in a laboratory. Such data (porosity, permeability, relative permeabilities, capillary pressures) are then entered in a numerical model which solves the multiphase flow equations for porous media. There are two limitations to this kind of approach. One is that the multiphase flow laws are poorly known (essentially the capillary pressure and the relative permeability laws). The other is that laboratory procedures introduce experimental artefacts which are not fully mastered (mainly the initial and boundary conditions). The purpose of this study is to provide improvements in these two areas as regards forced and spontaneous displacements.
