The paper reviews the issues of increasing energy efficiency of support systems for formation pressure (FPS) due to the reducing non-productive power loss. For this purpose, the structure of power consumers in FPS system has been studied and the elements with the most productive power loss revealed, as well as existing methods for pump stations control and their advancement ways analyzed.

The research works show that 55–60 % of non-productive power loss in oil production belong to the FPS system, and the great part of it falls within the pump units. Foremost, it is associated with non-efficient control of their operation regimes. Thereby, as the great majority of applied regulation methods is directed only to provide necessary injection capacity, power issue is not taken into account. It not only leads to the increase of power losses within the system, but also disables enhancement of prospects for control on operation regimes of pumping units. It was defined that with the method of regulation of productivity of pumping unit by changing the frequency of shaft rotation, it is possible to achieve the extension of technological options of pump station and minimize non-productive power loss as well.
