About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Marulk is a field in the Norwegian Sea, 25 kilometres southwest of the Norne field. The water depth is 370 metres. Marulk was discovered in 1992, and the plan for development and operation (PDO) was approved in 2010. The field is developed with a subsea template tied-back to the production, storage and offloading vessel (FPSO) Norne. The production started in 2012.
- Reservoir
- Marulk produces gas from Cretaceous sandstone in the Lysing and Lange Formations. The reservoirs are at a depth of 2800-2850 metres. Both reservoirs are in turbidite fans and have moderate to good quality.
- Recovery strategy
- The field is produced by pressure depletion.
- Transport
- The well stream is sent to the Norne FPSO for processing. The gas is then transported via the Åsgard Transport System (ÅTS) to the Kårstø terminal.
- Status
- The production from Marulk is in the decline phase. It is limited by the commercial agreement with Norne and the gas handling capacity on the Norne FPSO. Marulk utilises excess capacity when available on the FPSO.
