The Norwegian Petroleum Directorate has granted its consent for start-up of the Johan Sverdrup field in the North Sea.
Operator Equinor plans start-up sometime in November 2019 for the first phase of the field development. Construction phase two is slated to start in the fourth quarter of 2022.
Recently the last pieces of the Johan Sverdrup field centre were lifted into place. With this, the four platforms that make up the first phase of the giant development are in place.
The Johan Sverdrup Unit (JSU) was established by a decision in the Ministry of Petroleum and Energy in July 2015.
According to Equinor, investment costs for development of the first stage of construction are expected to be NOK 83 billion.
The field has a production capacity of 660 000 bbls per day.
Johan Sverdrup was proven by Lundin in the autumn of 2010 through well 16/2-6 “Avaldsnes”.
The main reservoir contains oil in Upper Jurassic intra-Draupne sandstone and lies at a depth of 1,900 metres. The quality of the main reservoir is excellent with very high permeability.
The remaining oil resources are in sandstone in the Upper Triassic Statfjord Group and Middle to Upper Jurassic Vestland Group, as well as in spiculites in the Upper Jurassic Viking Group. Oil was also proven in Permian Zechstein carbonates.
