Environmental safety of oilfield facilities

Accident risk mitigation measures

“Surgutneftegas” PJSC implements a long-term comprehensive program on increasing the operational reliability of the field pipelines, which results in the high level of environmental safety in the Company.

Reduction of accident risks at the oilfield pipelines is ensured by implementation of innovative technologies and diagnostic methods, timely preventive measures, replacing of pipelines, creation of modern methodology and technical regulatory basis that covers these issues.

“Surgutneftegas” PJSC takes a system approach based on package solutions for optimized quality control of construction and safe maintenance of field pipelines. The Company’s spheres of activity within the corporate program to increase the operational reliability of the field pipelines are:

pre-engineering work, design and examination of project documentation in terms of environmental safety;
destructive and non-destructive receipt inspection of pipe products (pipes, fittings) quality control of an internal coating;
dehydration of well production in initial water separation units;
use of pipes with an external and internal anti-corrosion coating;
pipeline inhibitor protection;
field pipeline corrosion monitoring and diagnostics;
equipping 100% of oil pipelines with pig launchers-receivers;
regular ground and air patrolling and inspection of field pipelines;
timely field pipelines routine repairs and overhaul;
conducting hydraulic calculations for field pipeline systems;
control over pressure and volume balance of pumped fluids;
creation and maintenance databases, computer modeling of the existing systems of field pipelines for the purpose of their optimization.

Receipt inspection of pipe products

Performance reliability of field pipeline systems is important at each phase of operation starting from receipt inspection and compliance verification of pipes. Receipt inspection is conducted for 100% of pipes for oil and oil and gas pipelines of “Surgutneftegas” PJSC.

To ensure environmental safety of the pipelines and maintain a high level of pipe products quality, the Company performs receipt inspection of the pipes using destructive and non-destructive methods. In 2025, 42.3% of the total number of pipes underwent receipt inspection using destructive methods.

Field pipeline corrosion monitoring

Pipeline corrosion monitoring, i.e. constant control of risk factors, causing the corrosion of field pipelines, allows the Company to assess the technical condition of a pipeline with a high degree of probability.

The main reason of disruption of field pipelines integrity is corrosion which occurs as a result of the aggressive transported liquids. Among other risk factors — the pumping mode of well production, temperature and the condition of the surface of pipeline metal.

“Surgutneftegas” PJSC developed and has been implementing the program for smart pigging of pressure pipelines using modern diagnostic equipment since 2008. Newly commissioned oil pipelines are equipped with pig launchers-receivers and undergo pre-launch smart pigging.

The corrosion monitoring using the gravimetric method is performed at 122 control points. This method is an effective tool for managing the efficiency of anti-corrosion measures taken that allows the Company among other things to track and adjust corrosion inhibition rate in time.

Based on the pipelines condition data the Company organized their routine repairs and overhaul. In 2025, 411.46 kilometers of pipelines underwent overhauls.

Inhibitor protection

Development of the system of pipeline integrity management in “Surgutneftegas” PJSC allowed us to decrease the risk of pipeline failures by 10 times. Corrosion inhibitors are used with continuous injection technology with a preliminary shock dose.

In 2025, 964 tonnes of inhibitors were used to protect 2,191 kilometers of field pipelines from corrosion. Corrosion inhibitors are injected by 80 chemical injection units, which are equipped with devices for automatic control with transfer of operating parameters to ASU TP “OKO-TsITS OGPD”.

Receipt inspection of corrosion inhibitors is made by means of infra-red spectrometry. The quality of all lots of corrosion inhibitors received during the year conformed to the standard specimen. Development of the system of pipelines integrity management ensures environmental safety of their operation.

Use of pipes with an internal anti-corrosion coating

The use of pipes with improved corrosion resistance and especially — with an internal anti-corrosion coating is the strategic way to implement measures aimed at minimizing environmental risks.

Timely application of pipes and fittings with an internal protective coating in the pipeline system is currently beyond question. Since 2013, “Surgutneftegas” PJSC has been implementing programs of capital construction, reconstruction and overhaul of oil and gas pipelines using only pipes with an internal anti-corrosion coating.

The Company employs products produced by its own plant that applies an internal anti-corrosion polymer coating on pipes and pipeline fittings. The production is arranged taking into the account the leading present-day practices using new high-tech equipment and best materials.

Since the commissioning, the Company has produced more than 7,300 kilometers of pipes and 281,000 fittings with an internal anti-corrosion coating. In 2025, the Company produced 731.8 kilometers of pipes and 28,157 pipeline fittings. The protection of welded pipe joints is ensured by the use of protective sleeves of our own production; in 2025, more than 43,000 protective sleeves were produced.

In 2025, “Surgutneftegas” PJSC introduced 752.3 kilometers of pipelines with an internal anti-corrosion coating, including 449.3 kilometers — according to the capital construction plan, 303.0 kilometers — as part of the overhaul program. The total length of field pipelines with an internal anti-corrosion coating of various application that the Company operates is equal to over 10.9 thousand kilometers, including 8.7 thousand kilometers of oil and gas pipelines (87%).

Dehydration of oil in IWSUs

Transportation of dehydrated oil is one of the efficient methods of corrosion protection. The Company has been using initial water separation units that are based on Heater-Treater three-phase separators at the booster pump stations.

Today, the Company operates 114 booster pump stations that are fitted with initial water separation units. The main technological equipment of facilities for preliminary and commercial oil treatment is a Heater-Treater.

Initial water separation units allow us to efficiently separate produced formation water for its further use in the reservoir pressure maintenance system. The Company rationally uses the water resources, reduces pipelines length and mitigates oil spill risks.

Apart from accident risk mitigation, the use of initial water separation units allows the Company to reduce the specific quantity of metal for pipelines and energy consumption during oil pumping at field pipelines, save and rationally use water resources.

Protection and rational use of land

Land reclamation and forest protection

An ecosystem approach allows the Company to consistently achieve high results during reclamation of used lands. The equipment and materials used by the Company help us minimize damage and the temporary load on the soil during land reclamation.

When choosing the reclamation technology, presented in the project documentation, the specialists are primarily guided by specific natural conditions at the location of the disturbed site. Technology and equipment for reclamation are unique and selected individually for each type of landscape.

After reclamation is completed, our specialists continue monitoring young plants, if necessary they set out new ones.

As part of measures taken by the Company to protect forests from fire, all stationary and mobile points of production sites are equipped with fire-fighting equipment, the machinery in use must be fitted with spark arresters. Mineralized fire barrier strips stretching in total for 66.05 kilometers are created and regularly being cut through along the borders of the forests. We set up and operate 52 stations with fire-fighting equipment, erected and updated 713 fire safety banner stands.

Every year, “Surgutneftegas” PJSC performs forest restoration works; in 2025, more than 4,794 thousand common pine saplings and more than 57 thousand saplings of larch were planted over the area of 2,371 hectares.

Pollution prevention and elimination

The priority direction of land protection is prevention of land from oil and oil products contamination. Timely elimination of such pollution consequences, if necessary, is done using Company’s own resources.

The Company maintains instant readiness of forces and means for elimination of oil and oil products spills and the following rehabilitation of polluted land. The complex of high-performance equipment includes:

oil skimmers designed to skim oil of various viscosity and under diverse weather and climatic conditions;
skimmer boats allowing to perform the work on the water surface;
all-terrain multipurpose units which make it possible to eliminate oil contamination in the coastal, wetland, and inaccessible area operations;
boats-trimarans for shallow water rivers and lakes operations;
vacuum dump trucks and tank trucks
self-contained pumps of various application (slurry, lobe, rotary, high-pressure pumps, etc.);
mobile rapid deployment booms with air blowers (both lightweight as well as reinforced, shore-protection and offshore);
mobile tanks for temporary storage of oil;
easy-to-assemble aluminum pipes for pumping recovered oil to waste accumulation site and subsequent disposal;
sorbent boom deployment and wringing machines, absorbent materials for multiple use booms;
sprinklers for fertilizers and bacteria treatment;
units for producing thermally exfoliated graphite absorbent.

To pump down and transport gathered oil we use vacuum dump trucks and tank trucks of Russian and foreign manufacture. For damming and ripping we use all-terrain caterpillar vehicles with excavators and other attached equipment.

To mitigate soil damage by temporary driveways of vehicles during elimination of pipeline failures and oil spills, during pipeline inspection and diagnostics, during land reclamation and peat digging we use temporary road mats MDP-MOBISTEK.

The oil spill prevention and response system of “Surgutneftegas” PJSC is unique and meets modern environmental safety standards for the oil industry.

Air protection

“Surgutneftegas” PJSC is the Russian fuel and energy complex leader in terms of efficient utilization of associated petroleum gas. Air protection measures are aimed at mitigation of a negative impact of production processes. It is achieved through reduction of emissions of pollutants to the atmosphere, particularly due to rational use of associated petroleum gas.

At present, the Company ensures a record level of utilization of associated petroleum gas — 99%. It was reached in 2012. The milestone of 95% was successfully passed in 2008. The level of rational use of associated petroleum gas amounted to 98.76% in 2025.

A comprehensive approach to air protection challenges allows “Surgutneftegas” PJSC to keep the specific indicator of air pollutant emissions into the atmosphere at the low level of 1.78 kilograms per 1 tonne of hydrocarbons produced.

Protection and rational use of water resources

The Company performs surface and ground water abstraction for drinking, household and technical water supply needs in strict compliance with the regulatory documents, and strives to reduce the fresh water consumption.

The Company ensured zero wastewater discharge into water bodies at its fields. All treated wastewater from the field facilities of “Surgutneftegas” PJSC together with associated water serve as injectant for a reservoir pressure maintenance system.

The Company’s water protection activity is aimed at prevention of water bodies pollution, saving and rational use of water resources. Due to the implemented package of measures, “Surgutneftegas” PJSC manages to minimize the impact on the water bodies. According to the monitoring results of the environmental components at the Company’s subsoil plots, the environmental impact is described as acceptable.

Waste management

“Surgutneftegas” PJSC uses innovative technologies that allow waste utilization, decontamination and processing. The Company manages to utilize and decontaminate 100% of generated oil sludge, tires with fabric and metal cords thanks to its own production.

A comprehensive approach to solving waste management tasks, technologies and equipment employed allow the Company to maintain low specific factor of waste generation and burial (0.018 tonnes and 0.004 tonnes per 1 tonne of produced hydrocarbons respectively).

Sludge pits reclamation

“Surgutneftegas” PJSC provides effective restoration of ecological functions of disturbed lands occupied by sludge pits by means of enhanced scientifically and economically proved technologies of reclamation. One of the most important priorities of the corporate Ecology program is to reduce the negative impact of drilling waste disposed in sludge pits.

Based on the results of an experimental scientific research carried out by the Company together with V.N.Sukachev Institute of Forest SB RAS (independent branch of Federal Research Center “Karelian Scientific Center” of SB RAS) throughout many years, a unique technology called forest rehabilitation has been developed and is widely used. In accordance with the stated technology, the drill cuttings are not isolated and not covered with soil, eventually they transform into soil forming material thanks to natural mechanisms of restoration of ecosystems. Forest rehabilitation enables to make full use of the natural self-healing potential, stimulates the natural process of overgrowing of sludge pits taking into account geological and climatic conditions of the region. In 2025, 9 sludge pits were successfully reclaimed using this method.

Exceptional efficiency of the method is proved by the results of research of phytocenoses formed on reclaimed sites. Such plant communities — that include the Red Book species — surpass dominating phytocenoses in productivity and biological diversity.

Surgutneftegas has been successfully using this technology for over 20 years: as a result of forest rehabilitation the very first sludge pits have transformed into forest areas.

The advantages of this method include:

less emissions of pollutants into ambient air due to reduced soil moving, motor and road vehicles operations;
the use of natural revegetation potential in the most efficient way;
absence of necessity for land transfer and borrow pit excavation.

Monitoring of natural environment components and control of production facilities operation

There is a production environmental monitoring system established in “Surgutneftegas” PJSC that provides constant monitoring of the environment and its assessment allowing the Company to timely identify the adverse changes that happen under the influence of anthropogenic and natural factors.

The observational network of environmental monitoring has been operating at the Company’s subsoil plots for many years. The area that has been monitored by now is around 150 thousand square kilometers. An extensive database has been developed that covers background pollution level of environmental components prior to the commencement of subsoil plots commercial development and after the fields are put in production, along with local environmental monitoring.

Industrial environmental control

In the year of ecology and specially protected natural reservations, the Ecological Council started functioning; it is chaired by First Deputy Director General of “Surgutneftegas” PJSC who supervises over the entire environmental management system of the Company. Industrial environmental control (IEC) is its integral part.

The Company has the effective vertically integrated two-level system of IEC. The tasks of Surgutneftegas Ecological Council are to mitigate the environmental impact of technological processes, the environmental risks and provide rational use of natural resources. One of the main functions is the environmental assessment, including the projected evaluation of the planned operations of the Company in subsoil plots adjacent to specially protected natural reservations.

Industrial control measures in the field of waste management can be either special-purposed or a part of complex measures ensuring compliance with environmental legislation as a whole. Inspectorial and ecoanalytical control are exercised according to the technological normative documents of “Surgutneftegas” PJSC.

IEC includes verification of compliance of the inspected facilities with the natural environmental legislation, ecological safety standards and in-house standards as well as adherence to waste management regulations, sanitary and epidemiological rules and guidelines of waste management provided by the Company’s internal documents, and draft regulations on waste generation and limits on waste disposal. During IEC, proposals on required actions and works and their deadlines are made and sample collection and ecoanalytical control results reports are issued.

Fulfillment of proposals and instructions is controlled without preliminary notification of the person to be inspected. The Company monitors fulfillment of the instructions every month. The results obtained are considered at the summing-up meeting. The number of the Company’s business units heads have received personal environmental performance targets developed on the basis of the results of industrial environmental control. Non-compliance with the received environmental performance targets results in loss of remuneration by the heads at the end of the reporting month.

IEC results are accounted, analyzed and summarized to be further used in business activities of “Surgutneftegas” PJSC.

Environmental education and professional training of employees

The priority is given to the professional training, namely, the environmental education of the Company’s employees which is important in mitigating risks resulting from the lack of their competence.

Biodiversity conservation

Biodiversity conservation is a key area of the environmental policy of “Surgutneftegas” PJSC, contributing to the maintenance of environmental balance and preservation of the original state of the territory where the Company operates.

Every year, “Surgutneftegas” PJSC increases the funding for the biodiversity conservation program. A record amount of money was allocated in the reporting period. Surgutneftegas invested more than RUB 10.7 billion in the biodiversity conservation program in 2025. The activities of this program are aimed at preventing (minimizing) the impact of production activities on the environment, preventing the depletion of water, land and biological resources in the areas where the Company operates.

The main vectors of the biodiversity conservation program of “Surgutneftegas” PJSC are:

protection of lands and water bodies;
reproduction of biological resources;
monitoring of the environmental components, including study of biota;
monitoring of biodiversity indicators species.

Traditionally, we monitor species that indicate biodiversity at the Company’s subsoil plots in Khanty-Mansiysky Autonomous Okrug — Yugra, the Republic of Sakha (Yakutia) and Tyumenskaya Oblast. Scientists from Lomonosov Moscow State University and research centers of the Siberian Branch of the Russian Academy of Sciences (the Tyumen Scientific Center and the Institute for Biological Problems and Cryolithozone of the Yakutsk Scientific Center) developed lists of species that indicate the biological diversity of key biocenoses (birds, mammals, vascular plants, mosses and lichens).

In 2025, as part of the corporate forest restoration activities, more than 4,794 thousand saplings of common pine and more than 57 thousand saplings of larch were planted — these coniferous trees have the best survival rates. Every year “Surgutneftegas” PJSC allocates significant financial resources to replenish the forests of Western and Eastern Siberia. The saplings, corresponding to the climatic zones of the regions, are delivered from plant nurseries.

For 13 years, “Surgutneftegas” PJSC has been engaged in the reproduction of aquatic biological resources in Khanty-Mansiysky Autonomous Okrug — Yugra, the Republic of Sakha (Yakutia), Tyumenskaya Oblast, Irkutskaya Oblast, Krasnodarsky Krai and Krasnoyarsky Krai. In 2025, the Company allocated more than RUB 59 million for the reproduction of aquatic biological resources. As a result, the population of whitefishes in the water bodies of the regions where the Company operates increased by 8.92 million juvenile peled and muksun.

In 2025, scientists from the Institute for Biological Problems and Cryolithozone of the Yakutsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences continued monitoring biological resources and cryolithozone at the subsoil plots of “Surgutneftegas” PJSC in the Republic of Sakha (Yakutia) within the biodiversity conservation program. Experts assess the man-made impact of the oil and gas industry on the environment, analyze the transformation of ecosystems and predict further changes. The received materials and recommendations are used during development of mitigating and compensatory environmental protection measures in the Company’s project documentation.

Over the years, the Company has been performing biological monitoring in subsoil plots adjacent to Numto nature park within the biodiversity conservation program in Khanty-Mansiysky Autonomous Okrug — Yugra. In 2025, St. Petersburg Federal Research Center of the Russian Academy of Sciences performed comprehensive studies and assessed the environmental impact around the well sites, constructed using the Company’s technology of pitless drilling. The scientists have noted that well pads ultimately exhibit a residual positive impact on biodiversity, manifested not only in the preservation of biological species, but also in their overall increase due to the creation of new ecological niches.

Soil scientists, geobotanists, chemists and other specialists from the Company’s own R&D and Project Design Institute take part in a number of studies. In particular, they monitor the hydrological regime of wetlands and evaluate the effectiveness of culverts. In general, “Surgutneftegas” PJSC attracts leading Russian scientific organizations that have extensive experience in conducting research in the region.

The Company fully implements measures to minimize environmental risks, mitigate a negative impact of its business activities on the hydrology of wetlands, and implements bird safety measures. Annually, we update the unique geographic information system — a database, which contains information on discovered habitat of rare and endangered biota representatives of the nature park.

The Company’s production facilities do not violate the ecological framework of the specially protected natural reservation and do not have a negative impact on the ecosystem of Numto nature park. These are the results of research work that has been carried out in these territories for 14 years.

R&D activities in the field of environmental protection

The Company cooperates with different scientific organizations many of which are incorporated into the Russian Academy of Sciences and performs in-house scientific research based on analysis findings obtained as a result of many years of environmental monitoring.

Throughout many years, “Surgutneftegas” PJSC has been cooperating with scientific organizations; most of them are incorporated into the Russian Academy of Sciences. From such organizations we receive an independent professional assessment of the environmental conditions in the area of our production operations, they also help us to develop and introduce the new and the most effective technologies which facilitate minimization of an environmental impact.

For almost four decades we have accumulated comprehensive analytical data by means of research in the field of environmental safety, environmental monitoring and environmental and biological assessment of the territory of the Company’s operations. This data allows us to develop the tactics and strategy of our environmental activity.

From 2012 to the present, as part of soil biological monitoring, with the help of the scientists from the country’s leading scientific institutions (Lomonosov Moscow State University, Federal State Budgetary Scientific Institution Federal Research Center Dokuchaev Soil Science Institute) and the institution responsible for specially protected natural reservations (Federal State Budgetary Institution Yugansky State Nature Reserve) the Company has been implementing an important environmental project that makes it possible to assess the impact of oil production infrastructure on the ecosystems of Numto nature park, the territory of which is located in close proximity to oil fields. In 2025, The Company again confirmed the absence of hazard not only to the habitat of flora and fauna rare species but also to ecosystems in general in the areas of its operations. In this regard, among the particularly important monitoring results it is necessary to emphasize the complete absence of signs of oil pollution on the surface of soils, plants and water areas, as well as the effectiveness of the currently effective “NO-GO ZONE” regime in the vicinity of production sites and roads, which excludes the presence in natural reservations of outsiders who are not involved in the implementation of any professional activity or who are not related to the local indigenous population.

In the reporting year, St. Petersburg Federal Research Center of the Russian Academy of Sciences conducted comprehensive studies of the environmental impact near the well pads built using the technology of pitless drilling, where cleaned drill cuttings are utilized as soil for earth filling of the drilling pads. The Company has been conducting research in this field at its facilities since 1998. Since the beginning of the research, there were no signs of man-made impact outside the 50-meter area, adjacent to the pads. In 2025, the analysis has once again confirmed the satisfactory condition of terrestrial and aquatic biotopes around the well pads built using the technology of pitless drilling. There were no records of significant disturbances in hydrological regime, soil and vegetation covers, as well as the state of hydrobionts of all levels (from phyto- and zooplankton to zoobenthos and ichthyofauna), terrestrial vertebrates and ornithologic fauna. Moreover, there is compensatory favorable impact: new ecological niches form at man-made sites, promoting not only preservation, but also growth of biodiversity.

In 2025, the Tyumen branch of the Russian Federal Research Institute of Fisheries and Oceanography carried out research work of water bodies in the area of the Company’s planned influence on the territory of Surgutsky District of KhMAO-Yugra. Ichthyological, hydrobiological, hydrochemical and hydrological studies have been carried out by the scientists to determine actual fish productivity of the lakes. The results obtained are used as objective and relevant initial data for calculating the damage caused to aquatic biological resources and their habitats and developing effective compensation measures to minimize the environmental impact.

The employees of the Institute for Biological Problems and Cryolithozone of the Yakutsk Scientific Center of Siberian Branch of the Russian Academy of Sciences have been carrying out biological research at the subsoil plots of “Surgutneftegas” PJSC in the Republic of Sakha (Yakutia) since 2014. The researchers carried out field studies of the active and upper layers of permafrost, land resources, surface water, soil, vegetation, water biological resources and wildlife. Biological monitoring is necessary to assess the environmental parameters of the territory potentially affected by oilfield facilities and track the dynamics of changes in ecosystems over time as well as to predict further changes. The scientists carried out monitoring of biological resources and cryolithozone in several stages and confirmed that none of the components of the ecosystem in the studied area showed signs of negative dynamics associated with exploitation of the Company’s fields. In 2025, according to the results of researches, it was found that there is no extensive process of permafrost degradation, main outlines of cryogenic landscapes had not changed. At the man-made sites there are primary stages of successional process, including active forest restoration of tree species due to natural seed deposition. An impact on state of species populations listed in the Red Book of the Republic of Sakha (Yakutia) was not revealed. The data analysis of game animals density shows that its number is rather stable.

The obtained results of researches in the field of biological monitoring of Surgutneftegas territories of presence and obtained analytical data allow us to increase the efficiency of our environmental protection measures. The results of the research are applied to make management decisions aimed at minimizing a negative environmental impact of the Company’s business activities.
