In 2020, Novatek-Yurkharovneftegaz was planning to test a new-pool wildcat in the Nyakhartinskoye discovery in Yamalo-Nenets Autonomous Okrug (Western Siberia). In late 2019, the company completed drilling of Nyakhartinskaya 21 with a PTD of 3,880 m. The well was drilled to 3,861 m at the Achimov reservoirs (Neocomian).    On 19 November 2018, Novatek-Yurkharovneftegaz reported a new discovery in the Nyakhartinskiy block. Nyakhartinskaya 1 was spudded in May 2018 and it was drilled to 3,450 m. The discovery was announced after obtaining gas/condensate flows from reservoirs BU9, BU1-2, BU0 and AU11 in the Lower Cretaceous section and a dry gas flow from reservoir PK1 (Cenomanian). Novatek registered reserves after completion of the well in March 2019. In January 2020, the company updated reserves based on test results of the discovery well and logging data of well Nyakhartinskaya 21. Recoverable 3P reserves are estimated at 2.6 Tcf of gas and 27 MMbbl of condensate.    The well was targeting reservoir BU10 (Valanginian) at the Nyakhartinskaya prospect with pre-drilled resources estimated at 2.3 Tcf of gas and 47 MMbbl of condensate.    The Nyakhartinskiy block covers 2,755 sq km between the Yamburgskoye and Antipayutinskoye fields in the Nadym-Taz Province. The area, covering the northern part of the Taz Peninsula and a portion of the Taz Estuary, encompasses four prospects with hydrocarbon resources (category C3) estimated at 65 MMbbl of oil, 3,570 Bcf of gas and 78 MMbbl of condensate. Hydrocarbon resources (categories D1+D2) of the block are estimated at 309 MMbbl of oil, 3,795 Bcf of gas and 93 MMbbl of condensate. Exploration has to be completed within seven years after registration of the license. Novatek-Yurkharovneftegaz won the block in 2016 with the offer of RUB 1,057 million (USD 16 million).
