About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Ringhorne Øst is a field in the central part of the North Sea, six kilometres northeast of the Balder field. The water depth is 130 metres. Ringhorne Øst was discovered in 2003, and the plan for development and operation (PDO) was approved in 2005. The field is developed with four production wells drilled from the Ringhorne wellhead platform. The production started in 2006.
- Reservoir
- Ringhorne Øst produces oil with associated gas from Jurassic sandstone in the Statfjord Group. The reservoir is at a depth of 1940 metres and has very good quality.
- Recovery strategy
- The field is produced by natural water drive from a regional aquifer to the north and east of the structure. The wells have gas lift to optimise production, and this will be expanded due to increasing water production.
- Transport
- Production is routed from the Ringhorne wellhead platform to the Balder production, storage and offloading vessel (FPSO) for processing, storage and export. The oil is transported by tankers. Any surplus gas is sent to the Jotun FPSO for export via Statpipe to the Kårstø terminal.
- Status
- The field is in its tail production phase, but there is still development potential. The amended PDO for Balder and Ringhorne, approved in 2020, extends the field’s lifetime and increases the production as a result of increased capacity in the area. A new infill well was drilled on Ringhorne Øst in 2025.
