Wellbore history

General

Well 24/6-3 was designed to appraise the Kameleon 24/6-2 discovery made in 1998. The well objectives were: to verify the field wide extent of fluid and gas contacts, eliminate geologic risk associated with the Boa structure, provide additional time-depth control, provide gas, oil and water samples, and to test local stratigraphic control of the T57 shale horizon.

Operations and results

Well 24/6-3 was spudded with the semi-submersible installation Deepsea Bergen on 18 April 2003. Drilling of the17 1/2" section was terminated at 253 m when the BHA became stuck in hole. Despite repeated attempts to free-off the BHA, the drill string was severed and the well temporarily abandoned for re-spud (well 24/6-4) some 20 m to the west of the original location. The well was permanently abandoned as a junk well after drilling of 24/6-4 was completed.
