Appraisal well 16/1-18 on the Edvard Grieg Field in the Norwegian North Sea has encountered approximately 62 m (203 ft) of oil-bearing conglomeratic sandstone sequence dated late Upper Jurassic, Lundin Petroleum said in a news release.

The well was drilled 2.4 km (1.5 miles) east of the Edvard Grieg production platform. The reservoir sequence was cored and an extensive logging program was acquired. Good reservoir quality was established in the upper 43 m (141 ft) and moderate reservoir quality in the lower 19 m (62 ft) of the oil bearing zone, Lundin said in the release. An oil down-to situation was established.

A production test (DST) was carried out in a 13-m (43-ft) perforation interval in the lowest part of the oil bearing zone. The test yielded more than 800 bbl/d of oil through a 28/64-in. choke, demonstrating good permeability and good vertical communication across the entire 62-m (203-ft) oil zone. The upper part of the reservoir with the best reservoir quality was planned to be perforated and tested in a comingled test with the lower zone, but this was cancelled due to operational issues, the release said. A mini-DST in the upper oil-bearing zone confirmed good quality reservoir properties.
