How this was calculated

Mobility ratio: M = (krw/mu_w) / (kro/mu_o). M < 1 is favorable (stable front), M > 1 is unfavorable (viscous fingering).

Displacement efficiency: Ed = (Soi - Sor) / Soi. Fraction of oil displaced in swept zone.

Volumetric efficiency: Estimated from Dykstra-Parsons coefficient. Ev ~ 1 - 0.5*Vdp (simplified).

Recovery factor: RF = Ed x Ev. Overall expected waterflood recovery as fraction of OOIP.
