1. Check the current production rate against the production target from FDP
   
   
2. If the diffference is big enough to justify the cost of production optimization (see point 8 below) then proceed to the step 3 below
   
   
3. Assess formation saturation in pay zones pressure based on well tests
   Assess formation pressure based on well tests
   
4. Simulate IPR/OPR based on the current WOR/GOR
   
   
5. Calculate the stabilized flow bottom-hole pressure
   
   
6. Gather the current bottom-hole pressure

8. Recommend the production optimisation activities to adjust 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.

In practise, the WFP analysis is often very tentative and production technologists spend some time experimenting with well regimes on well-by-well basis.
