Question 1 (5 Marks) CLOI A reservoir with initial pressure of 2500 psig is being produced through a vertical well completed with 2.5-in tubing. PVT analysis indicated the bubble point of the reservoir is at 2000 psig. (a) If the given test data shows that the well is produced at bottomhole pressure 2200 psig what type of method can be use to analyse the inflow performance relationship IPR? Justify your answer and sketch the possible IPR for the selected method. (b) If the given test data shows that the well is produced at bottom hole pressure 1500 psig. what type of method suitable to analyse the IPR?
