IPR is relationship between well bottomhole pressure and well production rate, usually in a form of a curve.

IPR curve shows productive capacity and performance of a well.

IPR curve is used in Nodal Analysis for production systems design, analysis and optimization.

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

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.
