The Dana-operated Western Isles Project will develop two discovered oil fields called Harris and Barra in the Northern North Sea, 160km east of the Shetlands and 12km west of Tern field.
It involves a subsea development of at least five production and four water injection wells tied back to a new build floating production, storage and offloading vessel (FPSO) with oil export using shuttle tankers.
UK Government sanction was granted in December 2012, drilling began in 2013 with subsea installation in summer 2014 and FPSO installation expected at a later date. Plateau production is expected to be around 40,000 boepd, adding more than 30,000 boepd to Dana’s UK production. The estimated field life is 15 years with the first oil expected in 2017.
Why we're doing this
The Western Isles Development Project is pivotal to Dana’s future growth. At a cost of $2 billion, it is the largest project currently being undertaken by the company and demonstrates Dana’s commitment to the North Sea. It is also Dana’s first end-to-end exploration and production project. By successfully delivering first oil, Dana is taking a major step towards being an operated rather than non-operated business. The project will ultimately deliver 40,000 barrels of oil a day, helping secure the UK’s future energy needs. Once operational, the development will bring hundreds of new jobs and create valuable opportunities for UK companies.
