On 7 November 2019, Gazprom Flot announced that it completed a new well for Novatek in September 2019. In early August 2019, Novatek-subsidiary Arctic LNG 1 spudded an appraisal well at the offshore extension of the Geofizicheskoye discovery (Western Siberia). Geofizicheskaya 65 with a PTD of 2,750 m, drilled by Gazpromâs Amazon jack-up, was targeting reservoirs of the Tanopchinskaya Formation (Hauterivian-Aptian). Water dept in the location is 12 m. The well was aimed at confirmation of gas pools in the Neocomian section (1,400-2,400 m) through open hole tests and conversion of 3P gas reserves in the main Cenomanian pool into 2P category. The company suspended the well after testing gas flows from reservoirs TP23 and TP12 in the Tanopchinskaya Formation (Neocomian) and from reservoir PK1 (Cenomanian).   Geofizicheskoye, discovered in 1975, is located in the Gydan Peninsula and the Ob Estuary (South Kara-Yamal Province). Recoverable 2P reserves of 19 pools distributed from Middle Jurassic to Cenomanian are estimated at 4.8 Tcf of gas, 21 MMbbl of oil and 9 MMbbl of condensate. The Cenomanian pool contains more than 90% of total gas reserves. Gas reserves of the discoveryâs offshore portion are estimated at 743 Bcf of 2P and 3.3 Tcf of 3P.
