Today, Artificial lift optimization has become very important in petroleum industries. A proper lift optimization can reduce cost of production and maximize recovery from the asset. The purpose of artificial lift optimization is to obtain maximum output under specified operating conditions.
Optimization of Beam pump and electrical submersible pump is a continuous process and a critical one but the use of PROSPER program modelling made field work easy for petroleum engineers.
The total field optimization involve optimizing the surface facilities and injection rate which can be achieved by the use of standard tool softwares.
Well level optimization can be achieved by optimizing the well parameters such as point of injection, injection rate and injection pressure.
All this aspects have been investigated and presented in this study by using experimental data and PROSPER Simulation programs.
The result show that well head pressure has great influence on the performance of artificial lift. Artificial lift performance can also be improved by controlling the pressure and gas injection of the downhole.
Obtaining optimum gas injection rate is important because excessive gas injection reduces production rate and increases production cost.
