Brief
Mobility Ratio determines the relative rate of one fluid to another (etc. water to oil).
- stable flow.
- unstable flow, fingering.
Equation
where[1]
- = Area, m2
- = Injected water formation oil factor, m3/m3
- = Net pay, oil saturated thickness, m
- = Hydrocarbon pore volume, m3
- = Injected hydrocarbon pore volumes, fraction
- = Cumulative water injection volume, m3
- = Porosity, fraction
- = Oil saturation, fraction
Related definitions
Dimensionless injected pore volume:
Injected movable pore volume:
where
- = Connate water saturation, fraction
- = Residual oil saturation to water, fraction
