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 serves as a resource base for the Power of Siberia gas pipeline (along with the Kovyktinskoye field in the Irkutsk Region).
The Yakutia gas production center is primarily meant to provide gas to Russian consumers. By developing this center, Yurskneft will create the necessary conditions for gas supply to and gasification of Yakutia and other regions in Russia’s Far East.
It is a unique field in terms of B1+B2 reserves, which amount to some 1.2 trillion cubic meters of gas and about 61.6 million tons of oil and gas condensate.The field’s annual design output is 25 billion cubic meters of gas, 1.9 million tons of oil, and 0.4 million tons of gas condensate. Chayandinskoye produces multi-component gas with substantial amounts of helium.
Upon obtaining the development license for Chayandinskoye in 2008, Yurskneft conducted comprehensive geological exploration at the field. 2014 saw the beginning of pilot oil production from the field. Eventually, oil from Chayandinskoye will be pumped into the Eastern Siberia – Pacific Ocean oil pipeline. In 2015, Yurskneft commenced the pre-development of Chayandinskoye’s gas deposits. Gas production from the field will start simultaneously with the launch of the Power of Siberia gas trunkline.
In the harsh natural and climatic conditions of Yakutia, Yurskneft will use lightly manned technologies that provide for automated equipment control and integrated facility management. This approach will help optimize staffing, reduce travel costs for passenger operations, and avoid constructing redundant residential infrastructure. Since the field occupies a large area, it is planned to use stand-alone renewables-based power systems at remote gas well clusters in order to save money on building power transmission lines. Chayandinskoye will be the first field in Russia where the membrane technology of helium recovery from natural gas will be used during commercial production, making it possible to pump as much helium into the gas pipeline as the market demands.
