Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 34/8-14 S with geological sidetracks A, B, C, and D were drilled on the Pan/Pandora prospect on the structural trend between the Visund and the Gimle Fields in the northern North Sea. The western part of the structure, the Pan structure, is defined by rotated fault blocks while the eastern part, the Pandora structure, consists of slided degradational blocks. The general objective of all the wells was to test the hydrocarbon potential in the structure. Both of the wells 34/8-14 S (Pan) and 34/8-14 A (Pandora) proved hydrocarbons in the Brent Group down to top of the Ness Formation shales. A sidetrack, 34/8-14 C was drilled to delineate the hydrocarbon contacts of the eastern Pandora structure towards the Visund Field. The contacts found in 34/8-14 C were shallower than in the 34/8-14 A well, at depths similar to 34/8-9 S well in the neighbouring S1E segment of the Visund Field. Further, all three 34/8-14 well bores had a non-prognosed pressure depletion of 21-23 bar. Well 34/8-14 B was therefore drilled into the Visund segment S1A to measure the pressures and check the hydrocarbon contacts in Visund.

Operations and results

Wildcat well 34/8-14 B was kicked off at 2365 m in well 34/8-14 A with the semi-submersible installation Borgland Dolphin on 25 December 2008 and drilled to TD at 4079 m (2930m TVD) in the Middle Jurassic Rannoch Formation. The well was drilled with XP-07 OBM from kick-off to TD.

Top Brent Group in well 34/8-14 B was encountered at 3486 m (2806 m TVD RKB). The pressure points found in 34/8-14 B imply that the prospect area is most likely communicating with the Visund Field. The Visund S1A segment GOC and OWC contacts were found to be at 3567 m (2842 m TVD RKB) and 3588 (2851 m TVD RKB) respectively, in
