25/08/2008 Press release 47/2008: StatoilHydro ASA, as the operator of production licence 048, is in the process of completing appraisal well 15/5-7 on 15/5-1 Dagny. In 1978, well 15/5-1 proved gas and condensate in the Dagny discovery in strata from the Middle Jurassic, with recoverable gas and condensate volumes of 5.19 billion Sm3 and 1.67 million Sm3, respectively. The Dagny discovery is about 10 km northwest of Sleipner Vest in the North Sea.
The exploration target for the well was to prove oil in reservoir rocks from the Middle Jurassic under the gas discovery 15/5-1 Dagny. The well showed an oil column of about 100 metres in the Hugin formation and the size of the oil discovery has preliminarily been estimated to be within the range 15 - 20 million Sm3 recoverable oil equivalents. The well will be formation tested (mini DST), and comprehensive data collection and sampling has been carried out. A downflank sidestep will be considered to determine the oil-water contact. The Dagny discovery will be considered for development in connection with the Sleipner field.
This is the third exploration well in production licence 048. The licence was awarded in the third licensing round in 1977. The well was drilled to a vertical depth of 4037 metres below sea level and terminated in the Skagerrak formation in strata from the Upper Triassic. The sea depth was 119 metres. The well will be permanently plugged and abandoned. The cost of drilling the well was shared between production licence 048 and production licence 029.
The well was drilled by the semisubmersible drilling facility Transocean Winner, which will proceed to production licence 212 C in the Norwegian Sea to drill wildcat well 6507/6-2 where StatoilHydro ASA is the operator.
