Improved Method of Relative Permeability Measurements Using Steady State Technique
Year: 2025
Type: conference-paper
Abstract: This paper presents an enhanced method for measuring two-phase relative permeability curves using thesteady state technique. Traditional methods rely on post-experiment calibration of saturation profiles, whichmeans the experiment is conducted without real-time saturation data. Our approach calibrates onedimensional X-ray or Gamma-ray scans at the beginning of the experiment using methanol as a calibrationfluid, providing direct in-situ saturation profiles throughout the test. This allows for better control and designof fractional flows and pump flood rates. Experiments were conducted using live-oil-brine fluids oncarbonate rock samples from a giant oil reservoir in the Middle East. The new technique offers faster, moreaccurate data acquisition over a wide range of saturations and provides real-time quality assessment of thedata.
