Russia's state-owned oil firm Rosneft has announced that it has made its first oil discovery in the Laptev Sea in Russia’s eastern Arctic following a geological study.
During the drilling of the Tsentralno-Olginskaya-1 well from the shore of the Khara-Tumus Peninsula on the shelf of the Khatanga Bay of the Laptev Sea, three core samples were taken from depths of 2305 to 2363 meters, which showed high oil saturation dominated with light oily fractions.
The Khatanga licence area is located in the Khatanga bay, the Laptev Sea in the North of the Krasnoyarsk Region.
Rosneft has been working in the Laptev Sea since 2014. Tsentralno-Olginskaya-1 is the first well that will be drilled under the offshore area of the Laptev Sea.
In a statement Rosneft said: "On the basis of primary studies already, it can be concluded that a new oil field has been discovered, the volume of the resource potential of which is increasing as the drilling continues."
Rosneft owns 28 licence areas on the Arctic shelf with the total resources of 34 billion tonnes of oil equivalent. The oil firm said that preliminary estimates suggest that the Laptev Sea’s total potential could be 9.5 btoe.
