Tullow Oil abandons Norwegian well

Friday, February 21 10:27:02

Irish-owned explorer, Tullow Oil, today said its well on the Langlitinden prospect in Norway, in which it has a 15pc stake, will be plugged and abandoned after it failed to find commercial levels of oil or gas.

Operator and 20pc owner of the site, Det Norske Oljeselskap ASA, said it drilled down to 2,878 metres below sea level and found oil in the main triassic formation reservoir at the site. However, after extensive data sampling, including cores, wireline logs and fluid sampling, the quality was deemed to be poor and unlikely to justify further field development.

The other partners on the site are Lundin Petroleum PLC, which holds 20pc, Rocksource ASA, which holds 5pc, Petoro AS, which holds 30pc, and Atlantic Petroleum P/F with a 10pc interest.

The news comes just two months after Tullow also had to plug and abandon an exploration well it had drilled in the 551 licence on the Mantra prospect offshore Norway. It had discovered reservoir quality sands at the site, but said all the intervals were water wet.

Tullow holds an 80pc working interest in the 551 production licence and is partnered by Det Norske with a 20pc interest.
