In March 2019, Lukoil-Zapadnaya Sibir received an exploratory license for the Tazovskiy Zapadnyy block in Yamalo-Nenets Autonomous Okrug (Western Siberia). License SLKh02575NP is valid until March 2026. A long-term combined license for the block was available in December 2018 when it was auctioned but the auction became invalid due to lack of participants. It is understood that Lukoil decided to secure exploratory rights for the area instead of waiting for a new auction.  The Tazovskiy Zapadnyy block covers 1,170 sq km in the eastern part of the Nadym-Taz Province and encompasses the Tazovskaya Zapadnaya prospect with hydrocarbon resources estimated at 8.6 Tcf of gas and 316 MMbbl of condensate. Seismic coverage amounts to 1,921 km of 2D data and 28 sq km of 3D data. Five exploratory wells have been drilled in the area. Hydrocarbon resources (categories D1+D2) of the block are estimated at 72 MMbbl of oil, 9.4 Tcf of gas and 38 MMbbl of condensate.
Lukoil secured sole 8-year rights to the Tazovskiy Zapadnyy block (1170kmÂ²) in the Yamal-Nenets AO under licence SLKh02575NP.
