As of December 31, 2015, Slavneft’s oil equivalent reserves, which were estimated under the 2P (total proved + probable) category in accordance with the PRMS (Petroleum Resources Management System) standards, made 5.12 mln bbl that practically corresponds to the 2014 volume. Associated petroleum gas reserves under the 2P criteria increased by 7.8% during the year and amounted to 706 billion cubic feet.
According to the independent audit results, Slavneft’s oil equivalent reserves under the 3P (total proved + probable + possible) PRMS classification also remained at the level of the previous year and made 7.83 bln bbl. The 3P gas reserves increased by 5.9% and amounted to 925 billion cubic feet in the reporting period.

The Company’s total proved oil reserves, which were estimated under the more conservative SEC (Securities and Exchange Commission) LOF (life of field) methodology, made 1.77 bln bbl as of the year end. The gas reserves under the SEC LOF criteria are evaluated as 352.6 bln cubic feet.

In 2015, the Company discovered 13 new hydrocarbon deposits at four license areas, i.e. at the Tailakovsky, Agansky, Pokamasovsky and Zapdno-Ust-Balyksky license areas, located in the Khanty-Mansi Autonomous Area – Yugra. 

In 2015, the independent audit of Slavneft’s hydrocarbon reserves was carried out at 35 fields, 33 of which are situated in KhMAO–Yugra and 2 of which are in the Krasnoyarsk region. DeGolyer and MacNaughton, an international consulting company, performed the audit.
