During the Arctic exploration in 2021, Rosneft drilled six stratigraphic wells in the Laptev Sea for the first time in the history of scientific research and selected 415 m of core, the company said. The study of these samples will bring the country new knowledge about the geology of the region, experts hope. Expeditions organized by the company to study polar bears, Atlantic walruses, wild reindeer and white gulls will help preserve their populations.
Exploration of the subsurface
In 2021, Rosneft drilled six stratigraphic wells with a total depth of 840 m and selected 415 m of core. Representatives of the company told about this at a press conference dedicated to the results of the Arctic field season in 2021. The ship "Bavenit" worked in the Laptev Sea near the islands of Kotelny and New Siberia. It is unique in equipment and the only drilling vessel of its kind in Russia.
- Especially for this expedition, "Bavenit" was retrofitted with innovative equipment of domestic production, which makes it possible to improve the accuracy and quality of stratigraphic drilling (relatively shallow and not damaging to the environment. - "Izvestia"), - said Rosneft.
Now the extracted rock samples are transferred to the non-governmental Institute of development "Innopraktika" for laboratory studies, which will be held on the basis of the Geological Faculty of Moscow State University. Rosneft noted that thanks to the extracted core, geologists have the opportunity to look into the past for tens of millions of years.
Next year, work on stratigraphic drilling is planned to continue in the Chukchi Sea. The first deep-water studies in the Arctic Ocean will also be conducted.
"Scientists expect to receive new unique data on the geology of the Russian Arctic, which are extremely important not only for Rosneft, but, without exaggeration, for the entire world science," the company stressed.
The region is rather poorly researched, Dmitry Alexandrov, head of the Analytical Research Department at Univer Capital IC. And research using the latest equipment and modern technologies can really be very fruitful from the point of view of science, he agrees.
Arctic biodiversity
Within the framework of the national Ecology project, Rosneft has also committed itself to conduct a corporate program for the study, conservation and monitoring of polar bears, Atlantic walruses, wild reindeer and white gulls until 2023.
— In 2021, the second large-scale field season of this program was completed — four expeditions to the Arctic regions were conducted, thanks to which it was possible to obtain new data on the population of the studied species, - the company noted.
The collected data on the number, distribution, condition and behavior of animals speak about the current state of the Arctic ecosystem and will be useful for studying the impact of climate change and anthropogenic impact on animal life, Rosneft concluded.
As the chairman of the Public Council under the Ministry of Natural Resources Alexander Zakondyrin noted, the company pays great attention to environmental issues, as well as measures to preserve the biological diversity of species in its area of responsibility, when carrying out its production activities. Therefore, taking care of the environment can be called an integral part of the company's corporate culture, he told Izvestia.
Rosneft is implementing a comprehensive long-term scientific program in the Arctic, which includes geological, hydrometeorological and environmental studies, work is being carried out with the country's leading scientific and design organizations in cooperation with the Ministry of Natural Resources, Alexander Zakondyrin stressed.
Rosneft has drilled shallow stratigraphic wells in the north of the Kara Sea for the first time in the history of Arctic exploration. The project started in October. Its main task is to take a core sample for the subsequent acquisition of data on the geological structure and oil and gas potential of the North Kara basin. The drilling of stratigraphic wells as part of the Rosneft scientific expedition was carried out by the Rosgeologia vessel "Bavenit".
"The vessel can perform drilling operations at a water depth of up to one kilometer and drill wells to a depth of 500 meters. Actually, plans for 2021 already provide for deeper wells in the Laptev Sea. Our task is to drill wells up to 200 meters deep," - said Shumsky.
Director of the Department of Scientific and Technological Development and Innovations of Rosneft Alexander Pashali, in turn, noted that 10 wells were drilled in the Kara Sea as part of a scientific expedition and 6.5 tons of core were taken, which was sent to Innopraktika for further study. "These works, carried out this year, have shown their effectiveness. We expect to continue them next year in the eastern region of the Arctic and hope for the same successful implementation and great data from a scientific point of view," he said.
The amount will be invested in a coastal base maintenance of offshore projects in the Murmansk region till 2030.
On the eve of yet another completed aero geophysical survey company.
Foreign partners of "Rosneft" which participated in development of the Arctic shelf, want to keep relations with the company and aspire to return to the project in Kara sea. About it as informs RIA Novosti news agency, the special representative of the president of the Russian Federation on the international cooperation in Arctic regions and Antarctic, the councillor of directors of "Rosneft" Arthur Tchilingarov has declared.
Exxon Mobile and "Rosneft" to stop exploratory drilling offshore in the Kara Sea in the well, "University-1" in connection with the introduction of Russian oil companies against the EU sanctions and the United States, according to Bloomberg.
