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:
Gas Well IPR
- Darcy's law gas inflow equation:
- Pseudopressure
- C and n
IPR calculator software
- PQplot nodal analysis software is used to calculate the IPR curves. PQplot is available online at www.pengtools.com.
- Excel
