Basement oil tested in Luno area off Norway

By OGJ editors
HOUSTON, Apr. 6
– Lundin Petroleum AB’s Lundin Norway AS unit completed an oil discovery at Well 16/1-15 on the Tellus prospect on Production License 338 in the Greater Luno area of the North Sea off Norway.

Tellus is most likely a northern extension of Luno field, the companies said. They plan to sidetrack the well to ensure it will be included in the Luno development program (see map, OGJ, Apr. 4, 2011, p. 50).

At Tellus, Lundin encountered oil in a 50-m column including a 3-m thick Lower Cretaceous sandstone with excellent reservoir quality overlying porous, fractured basement. The oil is of the same type as at Luno.

Perforations in a fractured basement interval flowed 650 b/d of oil on a 40/64-in. choke. This is the first successful full-scale basement test on the Norwegian continental shelf.

The second test was perforated in the overlying sandstone interval and produced 3,900 b/d of oil on the same size choke. This test showed good flow properties and good pressure support, Lundin said.

An estimate of the discovered resources will be provided once the sidetrack has been completed.

Lundin Petroleum is operator of PL338 with 50% interest. Wintershall Norge ASA has 30% and RWE Dea Norge AS has 20%.
