Gazprom Holding intends to bring the Bovanenkovo field, which is the largest field in Yamal, to the design production level in 2021. The maximum annual production capacity is expected to be reached between 2021 and 2022. The initial gas reserves at the site are 4.9 trillion cubic meters; the design gas production level is 115 billion cubic meters per year. In the long term it should increase to 140 billion cubic meters per year due to connection of Neocom-Jurassic deposits.
