A total gas column of approximately 15 metres was encountered, of which 10 metres of sandstones of very good reservoir quality.
Deeper in the formation, about 25 metres of net water-bearing reservoir rocks were encountered, mainly of moderate reservoir quality.
Preliminary estimates place the size of the discovery between 6 and 15 MMboe of recoverable gas.
The well was drilled together with partner Wellesley Petroleum in license PL 1008.
The nearest hydrocarbon discovery is Total’s abandoned 6506/6-1 (Victoria) discovery from 2000. Victoria contains gas in the Jurassic Garn, Ile, Tofte, Tilje and Åre Formations, and was once regarded as one of the largest undeveloped discoveries on the Norwegian Continental Shelf.
Total did not continue with a development of this discovery due to difficult reservoir properties and high CO2 content (11 %) proven with the appraisal well of 2009, 6506/9-1.
To the east of Nidhogg, the wildcat 6506/6-2 was found dry, and to the north, another dry wildcat, the 6506/3-1 only saw traces of methane and longer chain hydrocarbons according to the NPD Factpages.
