NOVATEK’s 2022 Reserve Replacement Reached 282%

Moscow, 23 January 2023. PAO NOVATEK (“NOVATEK” and/or the “Company”) today announced that independent petroleum engineers, Advantage Energy (Russia), have completed their comprehensive appraisal of the Company’s hydrocarbon reserves as of 31 December 2022.

Total SEC proved reserves, including the Company’s proportionate share in joint ventures, aggregated 17,571 million barrels of oil equivalent (boe), including 2,431 billion cubic meters (bcm) of natural gas and 194 million metric tons (mmt) of liquid hydrocarbons. Total proved reserves increased by 7.1% as compared to year-end 2021, representing a reserve replacement ratio* of 282% for the year.

In 2022, the Company continued its systemic efforts to commence production of new reserves, boosting the share of proved developed reserves by 6% to further monetize its resource base.

NOVATEK carries on with its active exploration in the Gydan and Yamal peninsulas, which will contribute to future growth of proved reserves under the international standards.

The Company’s reserves were positively impacted by successful exploration at the Gydanskoye, South-Tambeyskoye, Verkhnetiuteyskoye, and the North-Chaselskoye fields, production drilling at the Utrenneye, South-Tambeyskoye, North-Russkoye fields and the Urengoyskoye field within Samburgskiy, Yevo-Yakhinskiy, Ust-Yamsoveyskiy, Olimpiyskiy license areas, acquisition of new licenses in auctions (the Arkticheskoye and the Neytinskoye fields), and the increase of ownership stake in Terneftegas to 100%.

Compared to the end of 2021, NOVATEK’s total proved plus probable reserves under the PRMS reserves reporting methodology, including the Company’s proportionate share in joint ventures, increased by 2.6% and aggregated 29,726 million boe, including 4,069 bcm of natural gas and 359 mmt of liquid hydrocarbons.
