In-house environmental monitoring


Summary report on results of industrial environmental monitoring within license blocks of OJSC “Surgutneftegas” In the territory of Khanty-Mansiysky Autonomous Okrug – Yugra 2016

Summary report on results of industrial environmental monitoring within license blocks of OJSC “Surgutneftegas” in Yamalo-Nenetsky Autonomous Okrug 2016 

Applying the latest technology and using the best up-to-date equipment, the Company conducts continuous monitoring of the state of the environment. On the basis of long-lasting observations, an extensive database of chemical and analytical studies has been developed that provides the rapid assessment and forecasting of spatial and temporal changes in the state of the natural environment caused by both anthropogenic and natural factors.

Prior to commencing the commercial production of the fields, Surgutneftegas studies the initial contamination of the components of the natural environment: surface and ground waters, bottom sediments, soils, snow and ambient air. The obtained data is used as background indicators for assessing the impact of anthropogenic burden during the Company’s activity.

With the beginning of field development, an observational network of local en-vironmental monitoring is designed, based on the results of preliminary studies of the initial contamination of the environmental components, and also taking into account the existing and planned location of man-made objects.

In addition to local environmental monitoring carried out at the license blocks in general, the Company pays special attention to environmental monitoring of man-made facilities, including monitoring the status of sources of emissions and discharges of pollutants, well sites, sludge pits and other waste disposal sites.

In 2016, environmental quality control was carried out at 110 license blocks of the Company at 3,897 control points, including:

when assessing the initial contamination and conducting local environmental monitoring of license blocks at 1,489 points of control;

during ecological monitoring of man-made facilities at 2,408 points.

Surgutneftegas has the license to operate in the sphere of hydrometeorology and related areas, including determination of the pollution level of ambient air, water and soil.

Laboratory study and research during environmental monitoring by OJSC “Surgutneftegas” are carried out both by specialists of in-house laboratories and by independent third-party organizations whose reports are used and accepted by the regulatory bodies when exercising regulation and supervisory functions.

Specialists of 11 in-house laboratories accredited in the field of analytical and radiation testing and equipped with the latest instruments perform systematic studies of the state of the components of the natural environment for the quick detection of negative changes related to a man-made impact.

The Central Base Laboratory for Ecoanalytical and Technological Studies of the Engineering and Economic Implementation Center of OJSC “Surgutneftegas” performs research by gas chromatography-mass spectrometry, gas and liquid chromatography. Here, the content of heavy metals, carcinogenic pollutants and natural radionuclides in all components of the natural environment is determined. Laboratories for physical and chemical analysis of R&D Design Works Center run by six oil and gas production divisions of the Company also conduct surface waters and industrial emissions monitoring.

An accredited production and research laboratory of OGPD “Talakanneft”, un-paralleled in terms of equipment in the region, has been operating in the Republic of Sakha (Yakutia) since 2009.

OJSC “Surgutneftegas” practises remote monitoring of its fields by air patrolling, including the use of unmanned drones, large-scale aerial photography and ultra-high resolution space imagery. Remote sensing data is used to make inventories of disturbed lands, develop and update projects for sludge pit reclamation, projects for local environmental monitoring and sampling schemes, perform landscape monitoring, assess current environmental situation at license blocks and solve other ecological problems.

Based on expert interpretation of Earth remote sensing data, the Company performs geobotanical monitoring in the area of sludge pits, which is an important aspect of environmental monitoring in OJSC “Surgutneftegas”.

In the reporting year, the monitoring program was continued for the surface water of Imlor Lake, the water area of which together with the adjacent territory was assigned the status of a cultural heritage site of local significance, the siteseeing at-traction “Sacred Lake Imlor”. Monitoring has been ongoing continuously since August 2013 at 10 sampling points.

According to environmental monitoring results, the environmental impact of Surgutneftegas’ production facilities is estimated as acceptable. The Company en-sures meeting environmental quality standards.
