Measurements of Relative Permeability for Steam-Water Flow in Porous Media
Abstract/Contents
- Abstract
- This report describes experimental efforts towards obtaining relative permeability for steam-water flow in a homogeneous porous medium under adiabatic steady-state conditions. The porous media used in the experiments were Berea sandstone core samples. Porosity and saturation distribution were measured using a high resolution X-ray computer tomography (CT) scanner. Steam fractional flow, crucial in evaluating relative permeabilities, was monitored using a computer data acquisition system for measuring temperatures, pressures and heat fluxes. In particular, two approaches were investigated: (1) the simultaneous injection of steam and water and (2) the injection of water while it goes through a phase change. Both methods required assumptions with respect to two-phase flow and heat transfer, which lead to uncertainty in the results. Nonetheless, injecting through a single line greatly simplified the experiments. In addition, the variation of absolute permeability with respect to changes in temperature and flow rate were investigated. The results indicated that absolute permeability is practically independent of temperature and flow rate.
