F3-FB

F3-FB, in which ONE has a 12.6% stake, is an oil and condensate field which straddles the F2a, F3 and F6 licences to the north of the Dutch North Sea. The field is located in the southern part of the Central Graben and consists of three separate Lower, Middle and Upper Graben Sands reservoirs. The field was developed using a concrete production and wellhead platform bridge-linked to a steel accommodation platform. The oil and condensate from F3-FB is loaded offshore. The gas is sent through the NOGAT system to the Den Helder terminal.

F3-FB is located 220 km north of the Den Helder terminal and was one of the four developments integral to the NOGAT system pipeline project. The first phase of NOGAT from L2 to Den Helder was completed in 1992 and the second phase via F15a to F3-FB was completed in 1993. The field was developed during 1992 and 1993 using a concrete production and wellhead platform, bridge-linked to a steel accommodation platform. The platform is supported by a Gravity Base Structure (“GBS”) which can store up to 200,000 bbls of oil. The main production unit has a capacity of 24,000 bbls/d of condensate/oil and 660 boe/d of gas, which was later upgraded to 800 boe/d.
