wlbHistory: General

The objectives of well 6204/10-1 were to prove economic hydrocarbon reserves in the J-prospect (Turonian) and support play concept and possibly prove hydrocarbon reserves in the Jurassic lead. Further objectives were to achieve stratigraphic information and possibly prove reservoir sand and new play concepts in the Tertiary, Turonian and Cenomanian levels.

Operations and results

Well 6204/10-1 was spudded with the semi-submersible rig "Deepsea Bergen"on 28 October 1995 and drilled to 2709 m in basement rock within the planned budget. The 30", 13 3/8" and 9 5/8" casing strings were successfully set. No drilling problems were encountered. The well was drilled with seawater / bentonite hi-vis pills / ANCO 2000 to 490 m and with KCl polymer mud from 490 m to TD. Four cores were cut, one in Tertiary and three in Cretaceous. No fluid samples were taken.

The well proved the geological model of the J- prospect. Unexpected conglomeratic sandstones devoid of fossils, probably eroded basement, were encountered in the lower part of the well and the well was terminated before reaching the planned TD.
No hydrocarbons were encountered, and the well was plugged and abandoned as a dry well.

Testing

No drill stem test was performed.
