Protection and rational use of land
The core activity of OJSC “Surgutneftegas” is oil and gas production, which provides for operation of hundreds of kilometers of pipelines, transporting oil, water and gas, devices and tanks for oil storage and processing. Measures for protection and rational use of land are aimed at prevention of possible contamination of land by oil, oil products, initial water and gas condensate, reduction of negative impact from construction of sites and infrastructure facilities.
Environmental safety of a modern oil producing enterprise is determined to a large extent by reliability of field pipelines. Reliability of pipeline system is important at each phase of operation. Incidents and accidents at pipelines may lead to significant material and environmental damage. Thereupon, it is of prime importance to develop and implement extensive measures to provide safety of oilfield pipelines utilizing the best materials and technology, total quality control of the works performed and materials used, provide corrosion protection.
To ensure environmental safety of the pipeline systems in 2017 the Company expects to:
- to perform destructive and non-destructive receipt inspection of tubular goods to verify compliance with the technical requirements;
- introduce more than 830 kilometers of pipelines with internal anti-corrosion coating;
- to perform internal pipeline descaling and magnetic pigging of 3,170 kilometers of field pipelines;
- employ pipeline inhibitor protection on 2,890 kilometers of pipelines with the expected cost of RUB 524 million.
- perform overhaul of 578 kilometers of field pipelines with the expected cost of RUB 4,547 million.
In compliance with the legislation in the sphere of environmental safety and prevention of emergency situations of the Russian Federation the Company developed, approved and implemented the Plan on prevention and elimination of oil and oil products spills at the facilities of OJSC “Surgutneftegas” at the federal level and correspondent local plans.
Every year in accordance with programs and project documentation the Company implements a complex of measures for technical and biological reclamation of used lands and bringing them to their applicable use and timely return to the Forest Fund of the Russian Federation. In 2017 the Company expects to exclude from the register of territories and water bodies of
Khanty-Mansiysky Autonomous Okrug – Yugra contaminated by oil, oil products and initial water 9 blocks with the total area of 5.0608 hectares, expected costs for reclamation and inspection is RUB 19.08 million.
The amount of the return of the reclaimed lands depends on the area of the land parcels leased for the objects of prospecting and exploration drilling and seismic exploration. In 2017, the Company expects to return to the forest fund of the Russian Federation 5,597.6281 hectares of reclaimed lands.
The Company developed and widely uses a unique technology called forest rehabilitation, it involves reclamation of sludge pits without backfilling. In 2017, 21 sludge pits are expected to be reclaimed using this method. The expected costs for technical and biological reclamation are RUB 43.02 million.
