Fractional Flow & a Buckley–Leverett Introduction

Inside this lesson
  • Define the water fractional flow $f_w$ and apply its formula
  • Recognise the S-shaped $f_w$-versus-$S_w$ curve
  • Explain mobility ratio and why a high ratio causes early breakthrough and viscous fingering
  • Describe the Buckley-Leverett frontal-advance idea and the Welge tangent conceptually
