Inflow Performance Relationship

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.

Oil Well IPR

  • Darcy's law inflow equation for the single phase liquid:
 q = \frac{kh}{141.2 B \mu}\ (\bar{P} - P_{wf}) J_D

Gas Well IPR

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