General

Well 15/6-1 is located ca 5 km north of the Sleipner Field. The primary objective of the well was Eocene sands.

Operations and results

Well 15/6-1 was spudded with the drill vessel Glomar Grand Isle on 7 August 1971and drilled to TD at 1679 m in Eocene sediments of the Hordaland Group. Initial drilling from the sea floor to 384 m was with sea water and gel. Below 384 m to a depth of 1247 m the mud system consisted of sea water and Spersene XP-20 Salinex with drilling detergent. From 1247 m to TD a fresh water Spersene XP-20 system was used. Due to problems with the casing seal assembly the well was abandoned without reaching its target. The vessel vas moved approximately 335 m east and a replacement hole (15/6-2) was drilled.

The only reservoir penetrated was a thick Miocene sand section (the Utsira Formation) between 768 and 996 m. No hydrocarbon shows were encountered.

No cores were cut and no wire line fluid samples were taken.

The well was permanently abandoned on 8 September 1971 as a junk well.

Testing

No drill stem test was performed.
