Update on Norvarg appraisal well

Det norske announces that the appraisal well (7225/3-2) being drilled on the Norvarg discovery, located in PL535 in the Norwegian sector of the Barents Sea, has confirmed the presence of hydrocarbons in the Kobbe formation based on the results of wire line logs and formation tests and cores.

The partnership has decided to perform a drill stem test (DST) on the well to assess the quality of the Kobbe reservoir and the volume potential in the north-eastern part of the Norvarg closure.

Appraisal drilling operations commenced on 25 April 2013. The well is being drilled using Ocean Rig’s Leiv Eiriksson semi-submersible rig. The well is located in 377 metres of water, approximately 275 kilometers north of the Hammerfest LNG plant on Melkøya.
