What is the Western Isles Development Project?

arrow_up

Open

The Western Isles Project (Dana 77% and Cieco 23%) 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.

Drilling began in August in 2013 with subsea installation in summer 2014 and FPSO installation at a later date.

The field was deemed commercially viable in 2010 and 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.

Who are the partners in the project?

Open

Dana (77%) and Cieco (23%)

What's the specific location of the project?

arrow_up

Open

Block 210/24a (Rest of Block) in Licence P472. 160km east of the Shetlands 12km west of Tern field.

What's the project schedule? Key milestone? First oil? Field life?

arrow_up

Open

Government sanction was granted in December 2012. 80 per cent of key contracts have now been placed. Drilling began in 2013, subsea installation in summer 2014, FPSO installation at a later date. Field life potentially 15 years.

What's the overall value of the project?

Open

$2 billion

What is the anticipated production output of the project?

arrow_up

Open

Plateau production at around 40,000 boepd - 77% production to Dana (30,000 boepd)

How many wells will be drilled? Where?

arrow_up

Open

A minimum of five production and four water injection wells. Additional development and exploration wells are possible.

Can you describe the technology solution?

arrow_up

Open

The development concept involves a subsea development tied back to a floating production, storage and offloading vessel (FPSO) with oil export using shuttle tankers. The new build FPSO is designed by Sevan Marine using proven technology best suited and designed to meet the metocean conditions such as high wave height and wind speed. The latest industry best practices and lessons learned will be incorporated into the design and operational procedures.

Why did you opt for an FPSO purchase rather than lease?

arrow_up

Open

The purchased FPSO provides the best economic solution and creates the greatest opportunity to maximise reserves.

Will this project bring real value to the UK?

arrow_up

Open

The Western Isles Development Project will bring hundreds of new jobs and create valuable opportunities for UK companies. Around 70 per cent of work on the project will be carried out by companies in the UK. It will also contribute towards the future of energy security in the UK. Using this type of FPSO maximises the recovery of hydrocarbon reserves for the UK both in discovered reserves and in future exploration and will generate substantial tax revenue.

What value will this project create for the UK?

arrow_up

Open

£100’s of millions in tax revenue, capital investment in engineering and manufacturing in the UK plus long term operating jobs.

How many jobs will be created?

Open

We anticipate around 200 permanent jobs will be created.
