J Area

Jade lies approximately 240-kilometres south east of Aberdeen in Block 30/2c and 30/7b in water depths of approximately 260 ft. It is a high-pressure/high-temperature (HP/HT) development, which consists of a normally unmanned installation (NUI) tied back via a subsea pipeline to the Judy facility from where all operations are controlled. Hydrocarbons from Jade were first discovered in 1995 and began production in 2002. Production from Jade is processed and exported through Judy.

Judy and Joanne are in Block 30/7a, 30/7d and 30/12a (often referred to collectively as J Block) in the UK central North Sea approximately 240-kilometres south-east of Aberdeen. They sit in Quadrant 30 of the J-Area with overlapping reservoirs. Judy is a manned platform with accommodation, production, and processing. Joanne is a subsea manifold with six subsea wells tied back to Judy. First production in the Judy field occurred in 1997. After being processed on Judy, gas is transported through the CATS Pipeline and liquids are transported through the Norpipe system to Teesside.

Jasmine is a gas condensate field located in Blocks 30/6a and 30/7a of the UK central North Sea approximately 255 kilometres south east of Aberdeen. Jasmine is the fourth development in the J-Area after Judy, Joanne and Jade. The development consists of a 24-slot wellhead platform (WHP) with bridge-linked accommodation and achieved first production in 2013. The Jasmine WHP is tied back to the Judy platform to the east via an 8-kilometre pipeline and a riser platform at Judy. Production from Jasmine is processed and exported through Judy.

The Talbot field lies within Blocks 30/12a and 30/13e, in the central North Sea, south east of the Judy platform and in water depths of approximately 245ft. The light-oil and associated gas field was discovered in 1970 and production commenced in 2024.

The development comprises a subsea drilling template and manifold with associated infrastructure and a pipeline connecting the Talbot field subsea facilities to the Judy platform. Hydrocarbons produced from the Talbot field are processed on the Judy platform and transported back to the UK mainland at Teesside supplying domestically produced energy to the UK energy system.
