In-house environmental monitoring

Surgutneftegas puts special emphasis on assessment of natural environment components at the license blocks. The Company’s effective system of long-term environmental monitoring aimed at observing natural phenomena allows us to timely detect and prevent negative changes arising from anthropogenic factors.

Production environmental monitoring (PEM) is performed for the purpose of preventing a negative impact of business activities on the environment, compliance with environmental quality standards and provision of rational natural resources management and reproduction.

The main objective of PEM in the vicinity of pipeline crossings over the watercourses, well sites, waste disposal landfills, sludge storage ponds, flares and other man-made facilities is to regularly monitor the environmental condition for timely identification of a specific impact of man-made facilities and development of measures for its mitigation or elimination.

The environmental condition is controlled across the areas of “Surgutneftegas” PJSC operations in accordance with the developed projects and programs for environmental monitoring: the observational network has been operating at the Company’s license blocks for many years. The area that has been monitored 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 2019, the condition of environmental components was controlled at 136 license blocks of the Company at 4,629 control points, including:

during assessment of the initial contamination and conducting local environmental monitoring of license blocks at 1,150 control points;

during environmental monitoring of man-made facilities at 3,479 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.

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 85 techniques. Physical and chemical testing laboratories of the R&D and production workshops of six oil and gas production divisions boast from 12 to 20 techniques. Apart from in-house laboratories, “Surgutneftegas” PJSC 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.

To assess the current environmental situation within license blocks, making inventories of disturbed lands, performance of landscape monitoring, development of projects on environmental monitoring and projects on reclamation, the Company practices remote monitoring by air patrolling, including the use of unmanned drones, large-scale aerial photography and ultra-high resolution space imagery. In 2019, geobotanical monitoring in the area of 248 sludge pits is performed based on expert interpretation of remote sensing data.

The results of production environmental monitoring have confirmed that environmental conditions at the license blocks of “Surgutneftegas” PJSC are favorable. The Company operates with a minimum environmental impact.
