New Exam From Schlumberger May 2018



➤ All types of available artificial lifting pumps are used to add 
additional energy to the natural lifting energy
                                                                     YES   NO                                              
➤ The gas lifting technique is used to enhance the well inflow performance. This is achieved by reducing the hydrostatic head pressure loss.
                                                                    YES   NO
➤ Straight line IPR is better than Vogel IPR for the artificial lifting systems.
                                                                   YES   NO    
➤ Pressure gradient curves are used to predict the inflow flow performance where a multiphase flow exists.
                                                                   YES   NO    
➤ Absolute open flow is detecting when the bottom hole flowing pressure dropped to zero.
                                                                   YES   NO  
➤ The production system pressure loss distribution formula for a natural flow well can be stated as below:
Preservior =Δp reservior + Δp borehole + Δp vertical line + Δp surf +Δp choke + p sep
                                                                   YES   NO    

➤ Pressure gradient curves affected by the wellbore deviation.                                                                              YES   NO    
➤ Acid stimulation is use to by-pass the near well bore damage.
                                                                   YES   NO 
➤ Positive Displacement is the main design concept of Electric submersible pumps.
                                                                   YES   NO  
➤ HF acid is the best treatment solution for sand stone reserviors.
                                                                   YES   NO 
                                 ========================
