Inflow Performance Relationship
Inflow Performance Relationship
(OP)
Hi Everybody,
I was wondering if anyone knows the Inflow Performance Relationship (IPR) equation? I would really appreciate your help.
Thanks,

RE: Inflow Performance Relationship
Go to the following page. It explains the IPR equation.

There are one of 4 methods that are used in oil wells
1. Constant PI (Productivity Index)traditionally used in high water cut wells
2. VOGEL which is used where more complex fluid mixtures are encountered
3. Composite IPR where the curve that is used is a hybrid of (1) & (2)
4. IPR plots using data supplied from actual well bore performance or reservoir characteristics studies
Water wells use constant PI (Productivity Index)as the fluid is less influenced by gas and not influenced by oil (gravity and decreasing volumes) etc.
All the best
