Experimental Measurement of Two-Phase Relative Permeabilities in Synthetic Vertical Fractures
Abstract/Contents
- Abstract
- Relative permeability characteristics in porous media have been studied extensively and are reasonably well understood. However there have been comparatively few studies of relative permeability in fractures. Given that geothermal reservoir permeabilities are almost always dominated by fractures, understanding of fracture relative permeabilities is essential for accurate geothermal reservoir simulation. Two-phase fracture flow was simulated using an artificial fracture created between an aluminum plate and a sheet of glass. The experiments simulated horizontal flow in a vertical fracture to compare with the work of Chen (2005) who made similar measurements on the same apparatus oriented horizontally. N2-water, steam-water, and CO2-water relative permeabilities were measured using both smooth and rough glass. Measured relative permeabilities were compared with the work of Chen and with known relative permeability models.
