Yaregskoe field is the Group's largest high-viscosity oil field. Discovered in 1932, it is located in the south of the Timan-Pechora, Ukhta District of Komi Republic, 20 km off Ukhta and covers two major areas under development: Yaregskaya and Lyaelskaya.
The field is comprised of two main producing structures: the Yaregskoye structure, developed by underground mining techniques and thermal steam treatment methods; and the Lyael structure, where oil is produced using counter steam-assisted gravity drainage (SAGD) technology.
Production at the field continues steadily growing due to drilling and commissioning of new power and steam generating facilities.
The field is the only one in Russia where oil is being mined. High profitability of oil production at the field is explained by the existing beneficial taxation of high viscosity crudes.
Yarega's heavy crudes have exceptional properties. They are used as feedstock for one-of-a-kind chemical products used in road construction, space industry, pharmaceuticals, and the production of ultra-low diesel fuels used to power the Northern and Arctic vessel fleets.
Lyayel structure. The use of counter steam-assisted gravity drainage (SAGD) technology reduces time for well construction and increases the oil recovery rates. LUKOIL was the first in the world to successfully implement counter SAGD project with bore length up to 1 kilometer.
Yaregskaya structure. The Company develops the field by underground mining techniques applying thermal-steam treatment methods. The use of directional drilling reduces the scope and cost of operations while speeding up the pace of bringing reserves into production.
