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.
RESULTS
In the presence of measurements of electricity consumption by pumping units and data on well-operation modes, it is possible to estimate the ESP efficiency. The given efficiency estimation algorithm is a convenient tool for monitoring the energy efficiency of exploitation of the producing well stock.
CONCLUSIONS
Conducted testing shows that with a high degree of certainty it is possible to recalculate characteristics of ESP for bench conditions, and if there is essential sample of field data, under operating conditions even if there are no data on the efficiency of individual nodes. The approach proposed in this article is scalable and can be extended as a methodological basis for wells with abnormal conditions of wells operation and for more complex designs of pumping units.
