Water management

Gazprom Neft implements action programmes that aim to minimise its volume of water consumption, mitigate environmental risks in water resource conservation and improve the environmental condition of water bodies and their coastal areas.

The Company regularly monitors water protection zones as well as surface water, groundwater and wastewater and assesses the bottom sediment conditions of surface water bodies in the areas where it operates. Scientists from the Polar Research Institute of Marine Fisheries and Oceanography are carrying out comprehensive studies of the water environment as well as key hydrological and hydro-chemical indicators of the water condition near the Prirazlomnaya offshore platform. Spending on industrial environmental control and monitoring of water bodies totalled RUB 25.9 million in 2016, a 10.6% increase from the previous year.

Key water resource conservation projects in 2016

  • Moscow Region: the installation of the ‘Biosphera’ treatment plants at the Moscow Oil Refinery. The complex consists of a multi-stage wastewater treatment system that includes mechanical, physicochemical, biological, filtration and ultrafiltration stages as well as a reverse osmosis unit. The launch of the ‘Biosphera’ plant in 2017 will enable the Moscow Oil Refinery to increase wastewater treatment efficiency to 99%, which will exceed the performance of Europe’s best refineries. The use of a multi-stage biological treatment system will enable the refinery to reduce water consumption by 60%, while 75% of the water will be recycled into the enterprise’s production cycle.

  • Omsk Region: preparations for the construction of enclosed treatment plants at the Omsk Oil Refinery. The advanced technological solutions for the multi-stage treatment of industrial effluents contained in the Omsk Refinery project drastically reduce the size of the treatment facilities and reduce emissions of harmful substances by several times. All industrial effluents at the Omsk Refinery will undergo mechanical, physicochemical, biological, filtration and decontamination purification stages. The final stage will remove possible harmful microbes, viruses and bacteria as well as mould and spores from the effluents. The plant will cut its consumption of fresh water in half by returning the treated effluents to the enterprise’s technological process. The project is included in a federal action plan as part of the Year of Ecology in Russia.

The ‘Biosphera’ system of the Moscow Oil Refinery can be considered an example of the best available technologies being introduced into the practice of Russian oil refining. The traditional setup was supplemented with highly effective methods of sorption and membrane purification, which will significantly increase the efficiency of purification using soluble substances.
