Determination of the Economic Efficiency from the Downhole Compensators’ Introduction, under the Average Elaboration to Failures

it is known that the paramount question of any new equipment using is its economic efficiency. The information about reactive power compensation devices inside the well has appeared in the scientific and technical literature in recent years. This is due to these developments’ interest from oil producing companies. The oil production prime cost toward the electricity’s cost accounts from 30% to 35% of the expenses. If we introduce, that the oil production by submersible installations does the power losses, which range from 20% to 40% of the electricity consumed, then technologies for improving the energy efficiency production have a great implementation potential. On the one hand, the introduction of downhole compensators leads to an increase in the purchasing cost, servicing, mobilizing or submersible installation renting. On the other hand, the downhole compensators’ using leads to the energy costs reduction and the production efficiency increase. In this regard, there is a need to determine the economic efficiency for the introduction of downhole compensators as part of a submersible installation at oil production facilities. The research presents a calculating method for the ownership total cost of the electric centrifugal pump installation equipped with the reactive power downhole compensator.
