Lundin Petroleum has completed two successful appraisal wells 16/3-8 S and 16/3-8 S T2, on the Johan Sverdrup discovery.
Appraisal well 16/3-8 S, on the Avaldsnes High, was drilled about 4km southeast of discovery well 16/2-6 and about 3km west of appraisal well 16/3-4. The well encountered 13m of late Jurassic Draupne sandstone, “with excellent reservoir quality and a very high net to gross ratio”. A drill stem test was performed and flowed at 4900 bbl/d through a 52/64in. choke.
Well 16/3-8 S encountered 67m of Zechstein carbonates with variable, but mostly tight, reservoir quality, with oil shows. A technical side-track, 16/3-8 S T2, was drilled to investigate petrophysical properties in the reservoir.
The well was drilled in the eastern part of production license 501, in the central part of the Norwegian North Sea, in 116m water depth, using the semi-submersible drilling rig Bredford Dolphin (pictured).
Lundin Norway is the operator in PL501 with 40% interest. The partners are Statoil Petroleum with 40% and Maersk Oil Norway with 20%.
Well 16/3-8 S is the 20th exploration and appraisal well drilled in production license 501, which was awarded in APA 2008.
The Bredford Dolphin will move to production license 484 in the Norwegian Sea to drill wildcat well 6608/10-16 for operator Noreco Norway.
Ashley Heppenstall, president and CEO of Lundin Petroleum said: "The test results from this well are as good as anything previously encountered on the Norwegian Continental Shelf. Prior to drilling this well there was a risk that the good quality Volgian reservoir thinned out or even disappeared on the Avaldsnes High area of the Johan Sverdrup field. This well has proven that this is certainly not the case and the Volgian reservoir is contiguous over this area."
Statoil’s latest appraisal well on the giant Johan Sverdrup field encountered a 4.5m gross oil column in sandstones, believed to represent the Statfjord Formation, said partner Det norske oljeselskap.
Appraisal well 16/2-19 was on the northern margin of the Johan Sverdrup field in production license 265.
The partnership has decided to drill a sidetrack well, about 1000m to the southwest, in order to clarify the northern extent of the Johan Sverdrup main reservoir of the Draupne Formation sandstones.
The licensees in production license 265 are Statoil (operator, 40% WI), Petoro AS (30%), Det norske oljeselskap ASA (20%), Lundin Norway AS (10%).
