Project Profile
Value: US$400 million
Location: Block 7/7 and 7/4, PL 148, Norwegian Continental Shelf
Water depth: 80 m
Start-up year: December 2014
Plateau production: 12,000 bopd (2014)
Gross reserves: 5.7 million boe (December, 2015)
The Brynhild (Nemo) oil field is located 55 km northwest of the Ula field and 38 km north of the Pierce field (UK).
The development solution is a subsea system of four wells, two producers and two water injectors, tied-in to the Haewene Brim FPSO located on the Pierce field in the UK. The Brynhild subsea production system consists of four horizontal x-mas trees, subsea control components, a multi-phase flow monitor module (MPFM), an integrated overpressure protection system (IOPPS) and umbilicals.
The Brynhild reservoir lies at a depth of 3,300 m in Ula formation from the Late Jurassic age. The sandstone was deposited in a shallow marine environment.
Discovered in February 2008, the Brynhild (Nemo) appraisal well, 7/4-2, was drilled to a vertical depth of 11,207 ft (3,416 m). The well encountered hydrocarbons in the Ula formation, but was not tested. The required data was obtained through an extensive data acquisition program, including reservoir fluid sampling.
