The Ringhorne field is located about 9 km north of the Balder FPSO and includes a platform with initial processing and water injection capabilities.  Production is routed to the Balder and Jotun installations for final processing, storage and offloading. Production commenced in February 2003.

Also in 2003, two new discoveries were made in the Ringhorne area.  Ringhorne West commenced production in April 2004, within a year of discovery, while Ringhorne Øst started to produce in March 2006. In 2007, the Ringhorne field produced an average of 98, 000 barrels of oil per day.

ExxonMobil is the operator and has 100% ownership in the Ringhorne fields, except for Ringhorne Øst where ExxonMobil's equity is 77.4%.  The other Ringhorne Øst participants are StatoilHydro (14.8%) and Petoro (7.8%).
