28/06/2013 Statoil Petroleum AS, operator of production licence 532, is about to complete drilling of wildcat well 7220/5-2.
The well was drilled about five kilometres north of the 7220/8-1 discovery well ("Skrugard") and about 200 kilometres northwest of Sørøya.
The objective of the well was to prove petroleum in Cretaceous reservoir rocks (the Knurr formation), as well as acquire information for the planned field development of Johan Castberg.
The well encountered gas in the Knurr formation. The reservoir quality was poorer than expected, and preliminary calculations show that the discovery is not commercially interesting. However, evaluation and analyses will be carried out to clarify the details regarding the resource potential in the discovery.
The well was not formation tested, but extensive data acquisition and sampling have been carried out.
This is the fourth exploration well in production licence 532. The licence was awarded in the 20th licensing round in 2009.
The well was drilled to a vertical depth of 1765 metres below the sea surface and terminated in the Tubåen formation in the Early Jurassic. Water depth is 398 metres. The well will be permanently plugged and abandoned.
Well 7220/5-2 was drilled by the West Hercules drilling facility, which will now proceed to production licence 608 in the Barents Sea to drill wildcat well 7219/8-2, where Statoil Petroleum AS is the operator.
