To the problem of improving the energy efficiency of the oil pipelines operation has traditionally been paid close attention in achieving the strategic goal of increasing the competitiveness of the Russian economy by reducing the energy intensity of the gross national product in general, and the operating costs of electricity in the pipeline transport of crude oil and petroleum in particular. In the context of the sustained trend of the crude oil rheology deterioration, the optimization of the oil mixture composition in units formed for trunk pipeline batching according to the criteria of the lowest energy costs is of practical interest, as well as the development of a methodology for assessing the efficiency and analysis of the possibility of layout for the batches of planned volumes of crude oil in the future supply from each producer.

There is a method for justifying the practicability of forming crude oil batches by the criteria of energy efficiency of pumping based on: the analysis of the viscosity isotherm of a binary oil mixture; relations for composition optimization of the mixture in oil batches formed for transport using batching technology; a method developed for assessing the efficiency of dividing the scheduled oil supplies into a system of trunk oil pipelines in the article. In case study of oil binary mixtures flow characteristics obtained experimentally, an estimation of the segregating batches efficiency was performed depending on the share of each sort of oil in the planned pumping, the scope of the proposed approach was defined, and results of calculations were presented. There is showed the possibility of reducing the energy consumption for pumping up to 4.5% subjected to the pumping target.
