15/10/2009 StatoilHydro Petroleum AS, operator of production licence 442, has concluded the drilling of wildcat well 25/2-17.
The well was drilled a little more than 20 km east of the shut down Frigg field and 12 km north of the Frøy field in the central part of the North Sea.
The objective of the well was to prove petroleum in Lower Eocene reservoir rocks (the Frigg formation in the Hordaland group). The well proved oil in the upper part of a sandstone unit in the Frigg formation, with good reservoir quality.
Preliminary estimates place the size of the discovery between 3 and 5.5 million standard cubic metres of oil equivalents. No formation test was conducted in the well, but extensive data acquisition and sampling were carried out.
If the discovery is considered in context with other oil resources in the vicinity, this gives total recoverable oil equivalents in the order of 10 to 30 million standard cubic metres, which is interesting with a view towards a possible development.
The well is the first exploration well drilled in production licence 442, which was awarded on 15 June 2007 (APA2006). The well was drilled to a vertical depth of 2171 metres below the sea surface, and was terminated in the Balder formation in the Lower Eocene. The water depth is 120 metres, and the well will now be permanently plugged and abandoned.
Well 25/2-17 was drilled by the Ocean Vanguard drilling facility, which will now proceed to production licence 437 in the Norwegian Sea to drill wildcat well 6608/10-13, where StatoilHydro Petroleum AS is the operator.
