The Chayandinskoye oil, gas and condensate field is one of the largest fields in eastern Russia. The field forms the backbone of the Yakutia gas production center and, along with the Kovyktinskoye field in the Irkutsk Region, serves as a resource base for the Power of Siberia gas pipeline. The Yakutia gas production center is primarily meant to provide gas to Russian consumers. By developing this center, Gazprom is creating the necessary conditions for gas supply and gas infrastructure expansion in Yakutia and other regions in Russia’s Far East.

Figures and facts
Chayandinskoye was discovered in 1983 in the Lensky District of the Republic of Sakha (Yakutia).
It is a unique field in terms of recoverable reserves, which amount to some 1.2 trillion cubic meters of gas and 61.2 million tons of oil and gas condensate.
The field’s annual design output is 25 billion cubic meters of gas.
Chayandinskoye produces multi-component gas with substantial amounts of helium.
Upon obtaining the subsurface use license for Chayandinskoye in 2008, Gazprom conducted comprehensive geological exploration at the field.
2014 saw the beginning of oil production from the field. This oil is pumped into the Eastern Siberia – Pacific Ocean oil pipeline.
In 2015, Gazprom commenced the pre-development of Chayandinskoye’s gas deposits.
In 2019, the field started to produce gas.
Chayandinskoye is characterized by a complex geological structure and special pressure-and-temperature formation conditions. This is why Gazprom is using cutting-edge technical solutions to develop the field.
In the harsh natural and climatic conditions of Yakutia, Gazprom is using lightly manned technologies that provide for automated equipment control and integrated facility management. This approach helps optimize staffing, reduce travel costs for passenger operations, and avoid constructing redundant residential infrastructure.
Since the field occupies a large area, stand-alone renewables-based power systems are used at remote gas well clusters in order to save money on building power transmission lines.
Chayandinskoye is the first field in Russia to use the membrane technology for helium separation from natural gas on an industrial scale directly at the production site, making it possible to pump as much helium into the gas pipeline as the market demands.
