The company said the dual-zone find could be "very material" but has been tight-lipped about possible reserves.
Analyst Tristone Capital has said that Moth could hold as much 50 million barrels of oil equivalent.
BP, Hess and BG Group all hold stakes in the find, where Oilexco farmed in for its 50% interest.
Moth lies in Block 23/21. The 23/21-6z discovery well was drilled to a depth of 14,616 feet and hit reservoir sands that were 605 feet thick in the Middle Jurassic Pentland, and 219 feet thick in the primary Upper
Jurassic Fulmar.
