Pumping of viscous fluid like heavy crude oil using Electrical Submersible Pump (ESP) resulted in significant pressure losses which effect on the ESP performance and efficiency, this situation increases the operating cost, this paper showing the results of optimization of ESP stage geometrical design parameters,for inlet to outlet impeller radii ratio, impeller inlet & outlet angles, diffuser inlet & outlet angles. This is performed using Surrogate method as an easy and reliable method in this concern in order to enhance ESP performance while pump viscous fluid especially like heavy crude oil to increase ESP efficiency to reduce operating cost.In this study, a mathematical model was developed for prediction pump performance by calculation pump theoretical head, then calculation friction losses across a pumping stage to get the actual pump head curve. From the obtained pump head versus flow rate, the output power is calculated and brake power from the shaft torque is calculated by using fluid velocity components, then to prove the reliability of the mathematical model, a correlation to be performed for it against actual pump, then a viscosity correction for pump performance to get pump performance while handling viscous fluid. By, design the mathematical model and its correlation, the optimization for pump geometrical parameters is performed using Surrogate method through MATLAB program, first step to build is to do the design of experiment to get data sample to feed the model and check the validity of surrogate model was performed. On model creation, the results can be applied to deduce the specific influence of each of the above mentioned parameter on pump efficiency by conducting screening process using Morris method and get the relation between most effective parameter on the pump efficiency. The optimum geometrical parameters for three different values of viscosities were conducted using generic algorism to get the optimum of the studied parameters, which can be applied for further similar situations.
