• Jade lies approximately 240-kilometres south east of Aberdeen in Block 30/2c. 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

• The Joanne field is a sub-sea development tied back to the manned Judy platform . The Judy/Joanne fields currently produce from 16 wells.
• Jade was developed using a normally unmanned wellhead platform and currently produces from eight wells. Production from Jade is exported via a sub-sea pipeline to the Judy platform where it is commingled and processed with Judy and Joanne production.
• Production from Jasmine Gas and Condensate Field is processed and exported through Judy
• Gas processed on the Judy platform is transported through the CATS Central Area Transmission System Gas Pipeline to the Teesside Gas Processing Plant TGPP and liquids are transported to Teesside through the Norpipe system.
