In this paper we study the innltration of DNAPL in a porous medium containing a single low-permeable lens. Our aim is to determine whether DNAPL innltrates into the lens, or not. A key role is played by the capillary pressure: DNAPL cannot innltrate into the lens unless the capillary pressure exceeds the entry pressure of the lens. In the model this is reeected by an interface condition for the...

This research aimed to obtain the petrophysical parameters of capillary pressure a sandstonefrom 3D modelling high-resolution rock images. By integrating number 2D slice results, plot capillarypressure vs water saturation was built. When performing digital simulations using 512 x pixels, theeffect on resulting image clearly seen interactive thresholding. The obtained porosity 29.5%while permeab...
