Optimization of operating costs in managing electrical submersible pumping systems

Abstract

Using the methods of analysis, the task of minimizing the specific operating costs for oil production by submersible ESP units was formalized. The analysis of the multidimensional parameter space of the “ESP-well” system made it possible to isolate the vector of controlled parameters, determine the range of admissible parameters, and also to simplify the problem of finding an extremum up to the three-dimensional case. An application of the method of Lagrange multipliers to the solution of the problem is considered.
