Rosneft Oil Company has been the primary within the historical past of Arctic surveys to drill shallow stratigraphic wells within the north of the Kara Sea. The work has been carried out throughout its huge analysis expedition. The mission’s fundamental activity was to gather core samples. The core is a useful rock materials, a direct supply of geological knowledge required to find out the age (stratification), composition and situations of formation for Arctic shelf rocks below analysis. The samples recovered are of nice curiosity for the aim of acquiring the newest knowledge on the geological construction and oil and fuel potential of the North-Kara basin.
Rosneft Oil Company is the biggest license holder for continental shelf areas. The Company is implementing a complete long-term analysis programme within the Arctic, which incorporates geological, oceanological, hydrometeorological and environmental research.
The North-Kara drilling was carried out with the Bavenit survey drill ship, some of the outfitted vessels in Russia. During the expedition, eight wells had been drilled to a depth of 90 m. Those had been the primary within the area and the northernmost on the Russian shelf. The fieldwork was carried out in compliance with the best requirements of environmental security and environmental safety. In complete, 6.5 tonnes of core had been sampled, and the drilling know-how was examined in deposits with various properties, corresponding to rocky terrigenous and carbonate ones, in addition to in tougher dispersion and semi-core deposits. Specially designed drill bits had been used for rocky and semi-rocky formations.
The core samples taken might be lab-tested by the use of Innopraktika and the Lomonosov Moscow State University Faculty of Geology. A collection of analytical research will enhance the reliability of forecasts of the oil and fuel potential of the Arctic’s sedimentary basins of various ages and supply a brand new geological mannequin of the North-Kara area.
The expertise gained throughout the expedition gives the idea to develop applied sciences for efficient examine of the Arctic shelf and to proceed the mission within the more and more extreme situations of the Eastern Arctic.
As a dependable person of pure sources, Rosneft has a large-scale environmental agenda for the Arctic. The Company is implementing an Arctic Biodiversity Conservation Programme, which incorporates monitoring and analysis on key animal species which might be indicative of the resilience of the northern ecosystem. Unique research of walruses and polar bears have been performed within the waters of the Kara and Barents Seas and the Franz Josef Land archipelago in 2020.
