Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 34/3-4 S was the first of two wells planned to test the Jordbær Sør-øst prospect east of the Knarr Field (previously the Jordbær discovery) on Tampen Spur in the North Sea. The objective of 34/3-4 S well was to investigate the potential gas hazard within sands of a Pliocene submarine canyon fill below 1300 m. After this, a planned sidetrack 34/3-4 A should continue to the main Jurassic target.
Operations and results
Prior to spud of the main well on 10 - 11 November 2014, a 9 7/8" pilot hole was drilled from seafloor to 1028 m. No shallow gas was seen.
Wildcat well 34/3-4 S was spudded with the semi-submersible installation Transocean Searcher on 13 November 2014 and drilled through the sands to TD at 1607 m (1605 m TVD) m in Miocene sediments belonging to the Hordaland Group. No significant problem was encountered in the operations. The well was drilled with seawater and hi-vis pills down to 1023 m and with Glydril mud from 1023 m to TD.
The prognosed Pliocene sandstones in the canyon in 34/3-4 S appears to be of Pleistocene age, and were fully evaluated over a vertical section of 252.2 m, and three separate intervals gave a total of 3.2 m of pay, with a porosity of 36.1%, and a water saturation of 54%.
No cores were cut and no fluid sample was taken.
The well was plugged back to the 20" shoe and abandoned on 26 November 2014 as a dry well.
Testing
No drill stem test was performed.

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
