Tullow Oil plc's Mantra well, offshore Norway, is to be plugged and abandoned after being classified as water wet.

Mantra, drilled with the 31/3-4 wildcat exploration well,was the first exploration well in the Tullow-operated 551 production license. It was targeting the Upper Jurassic Sognefjord Formation reservoir as the main target, with additional prospectivity in Paleocene Lista sands and Middle Jurassic Brent Group.

The wellencountered reservoir quality sands, but all intervals are water wet.

The semisubmersible drilling rig Transocean Barents was used to drill 31/3-4 to a vertical depth of about 2082m subsea before it was terminated in the Middle Jurassic Brent Group.

The well, about 10km north of the Troll C platform in the Norwegian sector of the North Sea, will be logged before being plugged and abandoned.

Tullow holds an 80% working interest in PL551 with partner Det Norske (20%).
