Statoil Begins Arctic Drilling Campaign
Statoil ASA began drilling a new injection well for CO2 gas on the Snøhvit field off the coast of Hammerfest, before starting work on a production well for replenishment of gas for Hammerfest LNG.
After the new CO2 injector is installed, the Songa Enabler (mid-water semisub) will move on to drill the first new production well at Snøhvit since the field came on stream in 2007. The drilling campaign is planned to last until Christmas.
Snøhvit is still the only LNG project in the world capturing and storing CO2 separated from the well stream in a dedicated formation offshore. So far more than four million tons of CO2 from Snøhvit have been stored. The stored CO2 is being monitored in order to ensure that it does not mix with the main producing reservoir.
“Hammerfest LNG needed replenishment of gas in order to maintain the high production and capacity utilzsation at the plant, while ensuring sustainable CO2 storage. This project is therefore important to Statoil,” said Geir Owren, asset owner representative for the project.
In the summer of 2015, an extensive marine campaign was performed. Pipelines and a template for the CO2 project were installed and tied in to the existing subsea facility on the Snøhvit field. The new subsea facility was built and installed without injuries and well within the budget of $295 million (NOK 2.5 billion).
The next big development step for Hammerfest LNG is the development of the Askeladd field, which is part of the plan for development and operation of the Snøhvit license. It is expected to come on stream in 2020/2021 and “will help ensure full utilization of the capacity at Hammerfest LNG,” according to Statoil.
