On 19 February 2018, Novatek won an auction for two Alrosaâs subsidiaries operating gas assets in Yamalo-Nenets Autonomous Okrug (Western Siberia). Two companies were auctioned as a single lot for RUB 30.3 billion (USD 0.53 billion). Â Geotransgaz operates a part of the Beregovoye field in the Nadym-Taz Province with 3P reserves estimated at 3.5 Tcf of gas and 131 MMbbl of condensate (Geotransgazâ share). Urengoyskaya Gazovaya Kompaniya (UGK) owns the Ust-Yamsoveyskiy license in the same province. The license covers 1,657 sq km and encompasses the Ust-Yamsoveyskoye gas/condensate discovery with 3P reserves estimated at 174 Bcf of gas and 5 MMbbl of condensate, a portion of the Urengoyskoye field with 3P reserves estimated at 2.7 Tcf of gas and 69 MMbbl of condensate and several undrilled prospects. Alrosa acquired Geotransgaz and UGK for USD 1.14 billion in 2012. According to some experts, the sale price could reach USD 1.2 billion but Alrosa decided to sell its subsidiaries below a market price due to its intend to quit hydrocarbon E&P business outside Yakutia (Sakha), the core area for the major diamond producing company.
