Answer:

shows the calculated IPR curve along with a straight line valid for PI 1⁄4 1, ... Inflow Performance Relationship Curve The Vogel correlation, as discussed in ..

Answer 2

Inflow performance relationship

Inflow performance relationship (IPR) analysis is very well developed for oil wells. It is less well developed for conventional gas, but there are tools that mostly do an acceptable job. J.V. Vogel (1968) presented an easy to use IPR relationship for oil wells as:

(3.5)q0(press)q0(max)=1−0.2⋅(PbhP¯)−0.8⋅(PbhP¯)2

M.K. Fetkovich adapted Eq. (3.5) to Eq. (3.1) (using graphical techniques to evaluate cp to yield:
