Micromodel Studies of Three Phase Flow in Porous Media
Abstract/Contents
- Abstract
- This report is concerned with the flow of oil, water and gas in a water-wet porous medium at the pore level. Silicon micromodels which were an exact replica of a Berea sandstone are used to represent a heterogenous porous medium. The interaction of three phases in a micromodel has been studied to provide quantitative information about pore-scale displacement processes. The motivation was to obtain important parameters that must be included in the development of a mathematical model for three-fluid constitutive relationship.These observed displacement mechanisms can subsequently be used to calculate three phase relative permeabilities and capillary pressures from a pore network model. Double drainage was by far the most readily observed displacement mechanism in the air/hexane/water system studied. Generally, the imbibition mechanisms, including double imbibition were not readily observed. For double imbibition, this could be ascribed to the fact that the mechanism occurred very quickly and it was very difficult to capture the events when they occurred. The other double displacement combinations were unfavorable as there was a strong affinity between the gas and its surrounding oil.The oil layers which resided between the wetting phase (water) and the non-wetting phase (gas) were stable and oil recovery was high.
