Southeast extension buoys Norway's Avaldsnes

By OGJ editors
HOUSTON, June 27
– Lundin Norway AS has confirmed a southeasterly extension of its Avaldsnes field in the North Sea off Norway and will sidetrack the 16/3-4 appraisal well to confirm the lateral continuity of the reservoir towards the west.

The 16/3-4 well, 6.5 km southeast of the 16/2-6 discovery well in PL501, proved an oil column of 13.5 m in Jurassic sandstone of excellent quality, Lundin said.

A high net to gross has resulted in net pay at the appraisal location in excess of that at the discovery well, the company said without giving pay thickness. Porosity averages 30%, and permeability is several darcies.

The production rate averaged more than 5,500 b/d of oil equivalent on a 60/64-in. choke. Total depth is 2,020 m.

The company said, “We will now sidetrack the appraisal well to provide information regarding the lateral continuity of the reservoir towards the part of the structure we had assumed in our previous resource estimates was nonhydrocarbon bearing. We will update our Avaldsnes resource estimates following the sidetrack and second appraisal well.”

The Bredford Dolphin semisubmersible will spud the second appraisal well on Avaldsnes, 16/2-7, immediately after 16/3-4.

Lundin Norway is operator with 40% interest. Partners are Statoil Petroleum AS 40% interest and Maersk Oil Norway AS 20%.
