In-house environmental monitoring

“Surgutneftegas” PJSC pays close attention to production environmental monitoring (PEM) which helps to constantly monitor the environmental condition. We do it in order to timely detect and prevent negative changes which can arise from anthropogenic factors.

Production environmental monitoring is a comprehensive system for organizing long-term monitoring, information gathering, predicting and assessing temporal and spatial changes in environmental components because of anthropogenic activity at the Company’s license blocks. Throughout the years of monitoring we have created a chemical analyses database which helps us to timely assess indicators and control compliance with environmental quality standards, preventing a negative impact of business activities on the environment. The database also allows the Company to ensure rational natural resources management and reproduction.

In order to timely identify a specific impact of man-made facilities and develop measures for its mitigation or elimination, Surgutneftegas regularly monitors the environmental condition at man-made facilities, including sludge storage ponds, waste disposal landfills, well sites, pipeline crossings over the watercourses and flares.

Over the years, “Surgutneftegas” PJSC has controlled the environmental condition across the areas of its operations in accordance with the developed corporate projects and PEM programs. The monitoring network functions at all license blocks of the Company. The area of monitoring is about 150 thousand square kilometers. An extensive database that covers the status of the environmental components of the license blocks prior to the commencement of their commercial development (initial (background) contamination) and after the fields are put in production is supplemented annually during local environmental monitoring.

In 2020, the condition of environmental components was controlled at 124 license blocks of the Company at 5,222 control points, including:

during assessment of the initial contamination and conducting local environmental monitoring of license blocks at 1,386 control points;

during environmental monitoring of man-made facilities at 3,836 points.

“Surgutneftegas” PJSC 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.

“Surgutneftegas” PJSC has substantial resources for effective environmental monitoring. Testing is carried out in 11 accredited laboratories fitted with the best equipment. The Central Base Laboratory for Ecoanalytical and Technological Studies of the Engineering and Economic Implementation Center is accredited for 145 measurement techniques; the production and research laboratory of OGPD “Talakanneft” — for 86 techniques; physical and chemical testing laboratories of the R&D and production workshops of six oil and gas production divisions use from 11 to 21 techniques. Apart from in-house laboratories, the Company engages laboratories of independent third-party organizations for environmental monitoring, and the results of their research are accepted by the regulatory bodies when exercising regulation and supervisory functions.

In 2020, we ensured sampling and analysis of 31,857 environmental components under environmental monitoring.

“Surgutneftegas” PJSC organized remote monitoring of fields by air patrolling, including the use of unmanned drones, large-scale aerial photography and ultra-high resolution space imagery. Remote sensing data is applied to update the environmental situation within license blocks, make inventories of disturbed lands, perform landscape monitoring, develop projects on reclamation and environmental monitoring. In 2020, geobotanical monitoring in the area of 206 waste disposal facilities was performed based on expert interpretation of remote sensing data.

The results of production environmental monitoring confirm that “Surgutneftegas” PJSC does its activity with the minimum environmental impact. Environmental conditions at the Company’s license blocks are favorable.
