The sustainable use of water resources, effective wastewater treatment, and preventing contamination of natural water bodies with oil or petroleum products are all key priorities for Gazprom Neft in the management of water resources.
Gazprom Neft monitors water protection zones, surface water, groundwater and wastewater, and assesses the condition of bed sediments in surface water bodies in its regions of operation.
Water withdrawal and consumption decreased mainly because of a reduction in water production from the Cenomanian strata which was, in turn, a result of a higher water cut at the company fields.
Building Biosphere biological treatment facilities at the Moscow and Omsk Refineries are among the key projects being implemented by the company around water resources management. These facilities feature a multi-stage wastewater treatment system, which includes mechanical, physical and chemical, biological, filtration and ultrafiltration stages, as well as a reverse osmosis unit.
The Biosphere facilities help to achieve wastewater treatment efficiency of 99.9%, and to reduce total water withdrawal three-fold. Closed-loop water treatment makes it possible to reuse more than 75% of treated water in the production process.
