pseudo-pressure function specific to fluid type
Synonym: Laminar Inertial Turbulent IPR @ model = LIT IPR @model
One of the most general form of IPR model:
a \, q + b \, q^2 = \Psi(p_r) - \Psi(p_{wf}) \quad , \quad p_b > p_r > p_{wf} |
where
| bottom-hole pressure (BHP) | |
| drainarea formation pressure | |
| bubble-point pressure | |
| laminar flow coefficient | |
| turbulent flow coefficient | |
pseudo-pressure function specific to fluid type |
It needs well tests at least three different rates to assess but obviously more tests will make assessment more accurate.
