An algorithm for determining specific power losses in a cable line, submersible electric motor, and pump is considered. Сalculated loss values are reduced to specific values in relation to fluid flow rate at the operating point, fluid density, head at the operating point and other significant parameters. Correlation coefficients of specific losses depending on equipment operating time and downtime were obtained. The identified dependences can serve as an additional factor when planning well maintenance and repairs to reduce oil production costs.
