Operating principle
Electrical submersible pumps are multi-staged centrifugal pumps Each
stage consists of a rotating impeller and a stationary diffuser.
The rotating impeller takes the fluids and imparts kinetic energy from the
rotating shaft to the fluids
The stationary diffuser converts the kinetic energy of the fluids into
potential energy then to pressure (head) .

Advantages & Disadvantages of ESP
One of the Application of PIPESIM is ESP pump design and installation.
17
One of the Application of PIPESIM is ESP
pump design and installation.
In this case study we will discuss:-
A. Production rate from a vertical well.
B. Production rate with the same vertical well after installation of ESP
pump.
C. Discuss the effect of ESP Pump installation in the vertical well
18
A-Production rate from a vertical well:-
1. Steps of vertical well design.
2. Calculate the well Production rate.
3. Sensitivity input of reservoir pressure.
4. Effect of Increasing water cut.
19
1-Steps of vertical well design.
20
Input data for the design:-
well – tubing – fluid stream.
21
A-Production rate from a vertical well:-
1. Steps of vertical well design.
2. Calculate the well Production rate.
3. sensitivity of reservoir pressure.
4. Effect of Increasing water cut
22
2-Calculate the well Production rate.
Operations – Nodal analysis:- Entering the outlet pressure.
23
Run the model :- stable point.

Application of ESP pump by using PIPESIM
In this case study we will discuss:-
A. Production rate from a vertical well.
B. Production rate with the same vertical well after installation of ESP
pump.
C. Discuss the effect of ESP Pump.
30
B. Production rate with the same vertical well
after installation of ESP pump.
1-Steps of ESP pump installation :-
ESP design
Pump selection
ESP calculation
Motor selection
2- calculation a production rate.
31
1-Steps of ESP pump installation :-
Artificial lift then ESP design
32
Pump selection:-
33
Pump calculations:-
34
Motor Selection:-
35
Calculating Production rate :-
Q=10000 STB/d Pwf=2400 psi

Application of ESP pump by using PIPESIM
In this case study we will discuss:-
A. Production rate from a vertical well.
B. Production rate with the same vertical well after installation of ESP
pump.
C. Discuss the effect of ESP Pump.
37
c. Discuss the effect of ESP Pump.
In the first case :- from graph
Stable point Pwf =2670 PSIA , Q= 7800 STB/D
In the second case :- from graph
stable point Pwf=2400 PSIA Q= 10000 STB/D
ESP Pump JD is to make a pressure aid.
