10/10/2008 Press Release 53/2008: StatoilHydro ASA, operator of production licence 048, is concluding work on appraisal wells 15/5-7 A and 15/5-7 AT2 (technical sidetrack) on the 15/5-1 Dagny discovery, which is located about 10 km northwest of the Sleipner Vest field in the North Sea.
Additional resources were proven by appraisal well 15/5-7 in late August 2008, which resulted in a range of uncertainty of 15-20 million standard cubic metres (Sm3) of recoverable oil equivalents for all of Dagny.
Water samples were taken and pressure tests carried out in the reservoir rocks, and the oil-water contact was confirmed. The wells were not formation-tested. The size of the discovery is now being adjusted up to a range of 21-27 million Sm3 of recoverable oil equivalents. Consideration will be given to developing Dagny together with the 15/6-9 S discovery, with tie-in to the Sleipner fields.
15/5-7 A was the fourth exploration well in production licence 048. The licence was awarded in the 3rd licensing round in 1977. The well was drilled to a vertical depth of 4130 metres below the sea surface and was concluded in the Sleipner formation in the Middle Jurassic. Water depth at the site is 119 metres. The costs of the well will be divided between production licences 048 and 029, and the well will be permanently plugged and abandoned.
The well was drilled by the semi-submersible drilling facility Transocean Winner, which will proceed to production licence 212C in the Norwegian Sea to drill wildcat well 6507/6-3 where StatoilHydro ASA is the operator.
