Inflow Performance Relationship Curve

3 Phase IPR calculates IPR curve for oil wells producing water.

3 Phase IPR solution was derived by Petrobras based on combination of Vogel's IPR equation for oil flow and contact productivity for water flow.

q = \frac{kh}{141.2 B \mu}\ (\bar{P} - P_{wf}) J_D

Vogel's IPR two-phase flow equation (oil + gas) and it's combination with single phase liquid
3 Phase IPR three-phase flow equation (oil + gas + water)

q_g=\frac{kh}{1422 \times 10^3\ T_R}\ (P_{\bar{P}} - P_{P_{wf}})\ J_D

PQplot nodal analysis software is used to calculate the IPR curves. PQplot is available online at www.pengtools.com.
