STOCKHOLM, Sweden – Appraisal drilling on the Avaldsnes discovery in the Norwegian North Sea has confirmed a high-quality oil-bearing sandstone reservoir in the Upper Jurassic.
The semisub Bredford Dolphin drilled the 16/2-7A side track of the second appraisal well, 16/2-7, in license PL501.
According to operator Lundin Petroleum, the side track encountered a gross reservoir column of around 25 m (82 ft) in the Draupne formation of which 17 m (56 ft) net was above the oil/water contact. Coring and logging confirm reservoir characteristics similar to those reported in the Avaldsnes discovery and appraisal wells.
The side track was drilled 400 m (1,312 ft) northeast of well 16/2-7 in a water depth of 113 m (370 ft).
Ashley Heppenstall, president and CEO of Lundin, said: "As compared to the successful second Avaldsnes appraisal well the side track has found a larger Jurassic reservoir section above the oil/water contact.”
Bredford Dolphin now heads to PL 406 in the North Sea to drill wildcat well 9/1-1 S for Premier Oil Norge.
