Statoil is the operator on the Oseberg field, located in blocks 30/6 and 30/9 in the northern part of the North Sea.
Well 30/6-B-51 AH is a subsea well tied to the Oseberg A facility. The well was drilled in 1996, but has not produced since 2007. There have been integrity problems in the well, and Statoil has decided to plug it permanently.
The PSA has now granted Statoil consent to use the Songa Trym mobile drilling facility to plug the well.
Statoil has allocated 45 days for the activity, which will start in late October. Water depth at the site is around 105 metres.
Songa Trym is a semi-submersible drilling facility of the Aker H-3 type, built at Aker Verdal in 1976. Major improvements to the facility were made in 2012. Songa Trym is operated by Songa Management AS of Stavanger. The vessel is registered in the Norwegian register of shipping and classified by DVN GL.
Due to its change of ownership, Songa Trym received a new Acknowledgement of Compliance (AoC) from the PSA in February 2013.
