Abstract
The article is dedicated to methods for estimation of efficiency of operating low production well stock equipped with ESP. Based on the results of bench tests of high-speed ESP and comparing with field data, adjusting coefficients of efficiency were determined and functional relationship of energy characteristics on the motor’s shaft speed, the obtained correlation proposed for recalculation of passport value to bench ones.

Materials and methods
Technological data from the field, the published data, analysis.
