Energy consumption and energy efficiency
Energy efficiency in production is an important efficiency driver for the entire business of Gazprom Neft, as energy costs make up a significant part of refineries’ total operating expenses. Hence, energy efficiency must be viewed as a vital success factor in terms of both economics and environmental safety.
The Company’s Energy Policy approved in 2013 lies at the heart of Gazprom Neft’s ISO 50001:2011 compliant energy management system. The consistent and comprehensive Group-wide approach to energy efficiency is formalised in the Company’s Energy Saving and Energy Efficiency Improvement Programme.
Upstream division
The Company’s Upstream Division exceeded 2018 targets under its energy efficiency programme by 72%, with energy savings across the Division amounting to 462 m kWh (₽ 1,504 m). Power consumption per tonne of produced liquid, the key energy efficiency metric, continued to fall, hitting 28.39 kWh/t.
2018 saw the overhaul of high-pressure multistage centrifugal ring-section pumps with a performance improvement of 3%. Slavneft-Megionneftegaz successfully tested electric submersible pump units with high-performance EC motors, with energy consumption at pilot wells falling by 25–30%. In 2019, the Company plans to install 25 similar units across the Division.

Downstream division
The Downstream Division’s energy savings under its energy saving and energy efficiency programme amounted to 3.3 PJ (petajoules) or 3,347 TJ (terajoules), including 170,400 Gcal of heat, 50,900 tonnes of natural fuel, and 9.3 m kWh of electric power saved by the Division’s companies. Total economic effect was ₽ 790 m.
Implemented as part of a large-scale refinery upgrade exercise launched back in 2008, the Energy Saving and Energy Efficiency Improvement Programme run at Gazprom Neft’s refineries made a significant contribution to the Group’s strong performance. At Omsk Refinery, impressive results came on the back of a new automated system for cleaning the heating surfaces of furnaces at the facility for deep conversion of fuel oil, optimisation of process furnaces, and installation of higher-performance insulation in the main steam pipelines. At the same time, Moscow Refinery saw systemic optimisation of furnace operation modes at the facilities for hydrotreatment of cat cracking gasoline, bitumen and hydrogen production, and oil distillation. On top of that, compressed air supply schemes at production facilities were optimised and the upgrade of heat and steam condensate equipment was completed.
