General
Well 34/7-11 is located in the Tampen Spur area in the Northern North Sea. Its overall purpose was to assess the hydrocarbon potential in the "B"-structure in the southern part of the block. The primary objectives were to establish the thickness and reservoir quality of the prospective Brent the Brent Group in Group, and to determine the OWC. The secondary objectives were to assess the potential of the Dunlin Cook Formation reservoir, the Statfjord Formation and the upper part of the Triassic Lunde unit B/C reservoir section. TD was prognosed to 2900 m.
Operations and results
Well was spudded with the semi-submersible installation Treasure Saga on 2 October 1987. The well was drilled through the Pliocene Late Miocene Nordland Group, and terminated at a depth of 861 m for technical reasons. The well was drilled with spud mud from top to TD.
No cores were cut and no wire line fluid samples were taken.
The well was permanently abandoned on 11 October 1987 as a junk well.
Testing
No drill stem test was performed.
No cuttings in this wellbore.

No scanned core photos available
No palynological slides in this wellbore.
No oil samples available.
