Rimfaks is due to come on stream in late November as the second of three Gullfaks satellites developed by Statoil in the North Sea.
The Gullveig field began production on 10 November, with the wellstream being piped to Gullfaks A for processing.
Rimfaks will follow as soon as the first production well has been completed. A gas injector is already finished, and the subsea installations can be brought on stream.
Once this field is producing, work is set to start on completing the first well for the third satellite - Gullfaks South. A new well on the satellites will then come on stream every month until all 24 planned in the first development phase are finished.
