body	p_s

the WFP Junction Point will be dynamic in time depending on current formation npressure pressure (see Fig. 2) and formation saturation (see Fig. 3).

Workflow

...

Check the current production rate against the production target from FDP
If the diffference is big enough to justify the cost of production optimization then proceed to the next step
Assess formation saturation in pay zones based on well tests
Assess formation pressure based on well tests
Calculate the stabilized flow bottom-hole pressure
Gather the current bottom-hole pressure

:
- adjusting the choke at surface
- adjusting the pump settings from surface
- changing the pump depth
- changing the tubing size
- changing the pump

The above workflow is very simplistic and assumes single-layer formation with no cross-flow complications.
