News Release

Mantra well result offshore Norway

24 December 2013 - Tullow Oil plc (Tullow) announces that the 31/3-4 exploration well on the Mantra prospect offshore Norway has encountered reservoir quality sands but all intervals are water wet.

The 31/3-4 wildcat was the first exploration well in the Tullow operated 551 production licence and 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 semi-submersible drilling rig Transocean Barents drilled 31/3-4 to a vertical depth of approximately 2,082 metres subsea before it was terminated in the Middle Jurassic Brent Group.

The well, located approximately 10km north of the Troll C platform in the North Sea, will now be logged before being plugged and abandoned.

Tullow holds an 80% working interest in the 551 production licence and is partnered by Det Norske (20% interest).
