WFP – Well Performance Analysis analysis is a comparative analysis between:
- the formation fluid deliverability (the ability of reservoir to produce or take-in the fluid) which is called WFP – Well Flow Performance
and
- wellbore fluid deliverability (the ability of well to lift up or lift down the fluid) and which is called OPR or TPR or VFP (equally popular throughout the literature)
It is based on correlation between surface flowrate
and bottomhole pressure
as a function of tubing-head pressure
and formation pressure
and current reservoir saturation.
