The well was drilled about 27 kilometres southwest of the Skarv field in the central part of the Norwegian Sea and a few kilometres north of the Victoria discovery in Middle Jurassic reservoirs.

The primary and secondary exploration targets for the well were to prove petroleum in reservoir rocks from the Albian and Aptian Ages respectively, in Lower Cretaceous Intra Lange Formation sandstones.
In the primary exploration target (Warka), the well encountered a 27-metre gas column in sandstone layers in the Lange Formation, with moderate but uncertain reservoir quality. The gas/water contact was not encountered. No reservoir rocks were encountered in the secondary target.
Preliminary estimates place the size of the discovery between 50 and 189 MMboe recoverable. The licensees will assess the results of the discovery together with other nearby prospects with a view to a potential development to existing infrastructure.
The well was not formation-tested, but extensive data acquisition and sampling have been carried out.
The well was drilled to a vertical depth of 4960 metres below sea level, and it was terminated in the Lange Formation of Lower Cretaceous age. Water depth at the site is 400 metres. The well has now been permanently plugged and abandoned.
Well 6507/4-1 was drilled by the Leiv Eiriksson drilling facility, which will now drill wildcat well 6507/5-10 S in production licence 891 in the Norwegian Sea, where ConocoPhillips Skandinavia AS is the operator.
