Energy Consumption and Efficiency

An active energy-saving policy is a strategic priority for Gazprom Neft. The Company works hard to enhance energy efficiency and optimise the use of energy resources, implementing respective solutions. The Company implements a systematic approach to different areas of energy conservation and energy efficiency at its enterprises.

Gazprom Neft Energy Policy sets out the Company’s commitment to EMS maintenance and development and energy efficiency enhancement at its enterprises. The key energy conservation objectives of the Company defined by the document include:

  • Enhance energy efficiency of Company’s enterprises, while maintaining or improving reliability, safety and performance;
  • Reduce adverse impacts on the environment;
  • Reduce consumption of non-renewable energy resources.

The energy policy extends to all employees of Gazprom Neft. The document was placed on the corporate website and made available to all Company employees.

In 2013, Gazprom Neft completed the first stage and launched the second stage of its energy management system (EMS) project as per the ISO 50001:2011 standard.

The project began its first stage in September 2012. Within the first stage, the Company developed and implemented a unified regulatory and methodological framework for integrating energy management processes into existing business processes of the Corporate Centre and Gazprom Neft’s enterprises. A number of company-wide documents were developed and put into effect: the “Energy Efficiency Technical Policy”, “Power Supply Reliability Technical Policy”, and “Gazprom Neft Energy Policy.”

During the second stage, which began in the reporting year, EMS will be implemented at pilot enterprises: Gazprom Neft-Omsk Refinery and Gazprom Neft-Noyabrskneftegaz. Enterprise EMSs will be adjusted to comply with ISO 50001:2011 and then obtain compliance certificates. During the third stage, EMS will be cascaded throughout all enterprises of the Company, taking into account the lessons learned. The training of various employee categories will become an important part of project implementation.

Exploration and Production Segment

Energy efficiency is a priority for oil companies that spend a great deal of opex money on electricity. The Exploration and Production Segment (EPS) energy-saving measures are mainly intended to reduce the energy-related component of the overall unit production costs incurred by EPS facilities.

The key energy-saving measures in the EPS facilities include:

  • Use of energy-efficient electric centrifugal pumps;
  • Introduction of valve electric motors;
  • Optimisation of downhole equipment configuration and operation.
  • Optimisation of pump operation at the booster pump stations and preliminary water discharge units;
  • Optimisation of the power supply diagram, etc.

The main indicator of energy efficiency at EPS facilities is the specific energy consumption for the mechanical extraction of liquid.

Gazprom Neft is exploring new possibilities for using alternative energy sources. In 2013, NIS, a Serbian company in which Gazprom Neft has a 56.5% interest, took further measures to construct a wind farm at Plandiste. The project is begin implemented by NIS Energowind, a joint venture of NIS and private investors. In September 2013, works commenced to construct a substation that will ensure connection of the wind farm to EMC grids (grid company). Project completion and the commissioning of a 102MW electric capacity are planned for 4Q2014. In addition, in 2013, four small cogeneration plants were constructed (Sirakovo, Velebit-1, Velebit-2, Kikinda), and the geothermal energy project was further developed. In 2014, the Company will complete the first stage (2.5 MW) at the Kikinda site.
