Tullow Oil plc says that the Zumba exploration well (6507/11-11) in licence area PL 591 in the Norwegian Sea has not encountered hydrocarbons and will now be plugged and abandoned.
The primary objective of the well was to prove hydrocarbons in the Upper Jurassic Rogn Formation with a secondary target in the Mid-Jurassic Garn Formation of the Fangst Group. The well found no reservoir development in the Rogn Formation and, while the Garn Formation had good reservoir quality, no hydrocarbons were present in either target.
The well was drilled by the Leiv Eiriksson rig in 270 metres of water to a Total Depth of 2875 metres.
Tullow Oil Norge AS is the operator of PL 591 with 40% equity. Lime Petroleum Norway AS (25%), Rocksource (20%*) and North Energy ASA (15%) hold non-operated interests.
