Project characteristics
Aim of the project:
  • development of Otradninskoe GCF and supply of consumers in the town of Lensk, Sakha Republic (Yakutia), with natural gas; increase in natural gas balance reserves.
  • Gas stocks – С1-939 million m3, С2-5 400 million m3.
  • Forecast resources – Д1-39 018 million m3, С3-49 971 million m3
  • Stage 1 of the project will result in :
    • development of transport and electric power infrastructure, gasification of the town of Lensk;
    • increased power and industrial safety of western region of the Sakha Republic (Yakutia).
  • In middle-term perspective:
    • eliminated local nature of the regional gas supply system;
    • ensured export of gas;
    • achievement of the task to fill the export gas pipeline.
Volume of investment
  • RUR 12,980 m in 2010 prices ($ 457 m)
Infrastructure available
  • There is an airport, operating all the year round and able to accept almost all types of cargo planes; a large river port. Materials and equipment are delivered by railway to Lena station, then by water transport along the Lena River to the town of Lensk. From Lensk cargoes are delivered by motor transport along Lensk – Mirny motorway. Electric power supply of Lensky region comes from two HVL-110 kV Mirny-Lensk.
  • In close proximity to the field there is a a pipeline system East Siberia – Pacific Ocean. It is planned to construct a major gas pipeline Chayanda – Khabarovsk – Vladivostok on route Chayanda – Lensk – Olyokminsk – Aldan – Berkakit – Tynda – Skovorodino – Blagoveschensk – Khabarovsk-Vladivostok (along ESPO).
  • There are equipped fileds of commonly occuring mineral resources (mines).
  • HVL 220 kV Chernyshevsky - Mirny - Lensk - Peledui (double-curcuit) and VILYUI federal motorway on route Mirny - Lensk – Peledui – Vitim – Nepa – Ust-Kut are under construction.
Infrastructure required
