Brodgar discovered in 1985 is located in Block 21/3 of the UK North Sea. Callanish discovered in 1999, is located in Blocks 15/29b and 21/4a. Both fields were developed simultaneously as satellites of the already producing Britannia field. Production started in June 2008. The fields produce via subsea manifolds and two new pipelines linked to the Britannia platform. Net production in 2008 was 15 MBD of crude oil and 57 MMCFD of natural gas.

J-Block – Judy/Joanne/Jade

The Jade field came on line in 2002 and consists of a normally unmanned platform tied back to Judy. Together, the J-Block fields' net production in 2008 was 10 MBD of crude oil, 88 MMCFD of natural gas adn 3 MBD of NGL.

Jasmine

Operator: ConocoPhilips 36.5%. 
The exploration and appraisal wells drilled in 2006, 2007 and 2008 have confirmed the presence of a significant accumulation approximately 9 kilometres west of the Judy production facility. The results from these wells are being utilised to evaluate potential development concepts. It is anticipated that Jasmine will be tied back to the Judy production facility.

Oil and gas are delivered to the Piper B platform by pipeline, and from there oil travels to the Flotta terminal. Gas is transported via the Frigg pipeline to the St Fergus gas terminal. Net production in 2008 was 3 MBD of crude oil and 1 MMCFD of natural gas.
