Det Norske Allowed to Conduct Manned Underwater Ops at Jette Field (Norway)

Det norske oljeselskap ASA (Det norske) has received consent to carry out manned underwater operations on the Jette field in the Norwegian sector of the North Sea.

The Jette field is part of production licence 027D and is located in blocks 25/7 and 25/8 in the North Sea. The field is located approx. 180 kilometres west of Haugesund and six kilometres south of Jotun. Det norske is the operator of the production licence.

The field is being developed with a subsea solution that will be tied in to the Jotun B wellhead facility. The planned manned underwater operation is part of the work to connect the two production wells with the subsea facility, as well as connecting this facility to the Jotun B facility.

The operation is scheduled for October 2012, with an estimated duration of 10 days. Water depth at the site is 128 metres.  The Subsea7 company will carry out the activity and plans to use the DSV Seven Pelican diving vessel for the work.

First oil in 2013

Jette contains about 14 million barrels of oil equivalents, based on a 30 percent recovery rate. Daily production during the first year will constitute approximately 14 000 barrels. The estimated development costs of Jette amount to approximately 2.5 billion NOK. Given the current oil price, Jette may generate gross revenues amounting to 8 billion NOK.

Operational costs are lower compared to typical operating costs of stand-alone developments, thus enhancing the profitability of the development. Production is scheduled to commence during Q1 2013.
