Employees of the Komsomolsk Oil Refinery (part of Rosneft) and scientists from the Zapovednoye Priamurye Nature Reserve held a roundtable discussion on the conservation of the Steller's sea eagle population, a predator listed in the Russian Red Book. Leading Russian ornithologists from Lomonosov Moscow State University and Amur State Pedagogical University, as well as specialists from the regional environmental prosecutor's office, among others, participated in the event.

With Rosneft's support, the multi-year "Under a Strong Wing" project to study and protect Steller's sea eagles in Khabarovsk Krai is being successfully implemented. The joint effort between the Komsomolsk Oil Refinery and the Zapovednoye Priamurye Nature Reserve aims to study this important indicator species of the Amur River basin ecosystem.

The project included field expeditions to the Udyl Nature Reserve, as well as remote observations of birds using photo and video equipment and unmanned aerial vehicles. Furthermore, laboratory studies of fish samples, which eagles feed on, and raptor feathers were conducted for the first time.

Valuable data on the birds' lives has been collected, allowing ornithologists to conclude that, despite the overall decline in the global Steller's sea eagle population, the bird population in the Lower Amur region is showing signs of stability. The shores of the protected Lake Udyl remain the most favorable breeding habitat for the birds, where approximately 150 nests have been found.

During the discussion, experts noted the project's potential, as scientists still have many unanswered questions about the lives of Steller's sea eagles. Ornithologists also emphasized the critical importance of the project's findings for updating Russia's Red Data Book and developing conservation recommendations for businesses operating in the Amur River basin and on the coast of the Sea of Okhotsk. Furthermore, these materials will complement educational programs for schoolchildren and students.

Preserving the environment for future generations is a key focus of Rosneft's strategy. The Company and its subsidiaries are implementing a number of comprehensive programs to preserve biodiversity and natural resources in the regions where they operate, striving to ensure environmentally friendly production and minimize environmental impact. Significant attention is paid to ornithological projects. With the support of the Company's subsidiaries, research is being conducted and measures are being developed across the country to preserve and protect rare bird species, including Steller's sea eagles, wild geese, ivory gulls, and other birds.

Reference:

The Steller's sea eagle is one of the largest birds on the planet, nesting only in the Russian Far East. The global population numbers 5,000–7,000 individuals, of which approximately 1,200 live in the Khabarovsk Krai.

The species is listed in all existing Red Data Books as rare and highly vulnerable. The decline in the eagle population is largely due to human factors, but there are other factors as well: slow reproduction rates and changes in the hydrological regime of rivers.

Rosneft scientists have conducted a unique study of ancient* oil varieties.

Translation. Region: Russian Federation –

Geochemists from the Rosneft Research Institute in Tomsk have published** the results of a large-scale study of ancient oil varieties, conducted over 30 years. The findings are important for rethinking the history of hydrocarbon formation. A new understanding of oil structure will improve the accuracy of oil and gas potential assessments and the efficiency of reservoir development.

The aim of this unprecedented study, both in duration and data volume, was to investigate alkylbenzenes, a key component of oil that influences gasoline quality. From 1998 to 2025, specialists from the Tomsk-based corporate institute analyzed over 500 grades of oil from 11 oil provinces in Russia and abroad.

Thanks to advances in technology, a machine learning approach has been used to study the composition of alkylbenzenes in oil samples over the past two years. The developed models have accurately determined the origin of the oil and the conditions under which it formed.

In a number of ancient oil grades in Eastern Siberia (the Kuyumbinskoye and Yurubcheno-Tokhomskoye fields, developed by Rosneft Oil Company enterprises), a high concentration of tert-butylbenzene, a substance previously considered uncharacteristic of such geological formations, has been identified for the first time.

The study's results help to more accurately determine the original (parent) source of the oil: tert-butylbenzene indicates that the oil belongs to the Riphean period ("ancient" grades). Source data are used in basin modeling to predict oil migration, the potential for oil and gas potential in the area, and approaches to field development.

* Oil is extracted from rocks with a geological age of 1.1 billion to 5 million years – from the Meso-Neoproterozoic to the Cenozoic.

** The article “Composition and distribution of C3- and C4-alkylbenzenes in oil and oil source rocks from the Meso-Neoproterozoic to Cenozoic” by Nikolai Oblasov, Ilya Eftor, Ivan Goncharov and Svetlana Fadeeva was published in the authoritative international journal Organic Geochemistry, which specializes in research on all aspects of organic geochemistry.

Translation. Region: Russian Federation –

Source: Rosneft – An important disclaimer is at the bottom of this article.

Specialists from Rosneft's Ufa Research Institute have developed a unique software and analytical system for monitoring the integrity and improving the reliability of pipeline transport.

The software package continuously processes information about the properties of the hydrocarbons being pumped, as well as data from pressure sensors received at a frequency of up to 20 times per second, and if deviations are detected, it provides coordinates of the point of loss of pipeline integrity.

The new technology will help effectively monitor the integrity of pipelines transporting both processed commercial oil and liquid hydrocarbons with low gas content. To ensure reliable operation, methods and algorithms have been developed that take into account the specific installation conditions, design, and flow patterns of the pipelines. For partially processed hydrocarbons, this integrity loss detection technology is unique on the domestic market.

The implementation of the software package will significantly reduce environmental risks and the costs of eliminating the consequences of pipeline failures.

The results of pilot tests at the production facilities of Bashneft-Dobycha, Rospan International, and Samaraneftegaz demonstrated the high efficiency of the developed solutions. The project's economic efficiency includes reduced hydrocarbon losses, optimized operating costs, and increased pipeline infrastructure reliability.

Based on the results of the pilot implementation of the innovation, it is planned to scale it up to the Company’s entire pipeline complex.

Rosneft improves the accuracy of reserve assessments

Translation. Region: Russian Federation –

Source: Rosneft – An important disclaimer is at the bottom of this article.

Specialists from Rosneft's Ufa Research Institute have developed a methodology that allows for the highly accurate assessment of the potential of deposits with low-permeability clay reservoirs.

The essence of the innovation lies in a comprehensive analysis of the electrochemical and electrophysical properties of rocks. The researchers took into account the phenomenon of "capillary superconductivity," which is especially important when working with rocks with high clay content, small pores, and low permeability.

Traditional saturation determination methods in low-permeability clay reservoirs do not always provide accurate results, leading to potentially oil-saturated formations being mistakenly interpreted as water-saturated. This new approach significantly reduces the incidence of such errors.

The method has proven its effectiveness in reinterpreting geophysical well data at fields in Western Siberia. Implementation of this innovation will increase hydrocarbon production and ensure more accurate reserve assessments at mature fields.
