Three-phase Inflow Performance Relationship
3 Phase IPR Curve [1]
3 Phase IPR is an IPR curve calculated on the basis of total barrels of produced fluid, including gas.
3 Phase IPR curve is used in Pump Design software for pump sizing.
Math and Physics
The volume of 1 stb of liquid plus associated gas at any pressure and temperature is given by[1]:
The total volume of produced fluid rate (liquid plus gas) at any conditions of pressure and temperature:
is calculated as usual using:
- Vogel's IPR equation
- Composite IPR equation

Nomenclature
= volume factor, bbl/stb oil; bbl/scf gas
= gas liquid ratio, scf / bbl
= flowing rate, stb/d 
= solution gas ration, scf / stb
= total volume of produced fluid rate (inducing gas), bbl/d
= volume factor, bbl/stb
= water cut, fraction
Subscripts
- g = gas
- o = oil
- sc = standard conditions
- t = total
- w = water
