General

Appraisal well 6407/9-6 was suspended in 1986 as a possible water injection well after a successful oil and water injection test in the Late Jurassic Rogn Formation. The objective of the re-entry 6407/9-6R was plugging and permanent abandonment. A small gas leak from the wellhead was observed when the well was suspended. An inspection programme was initiated to monitor the wellhead and gas leak activity. A secondary objective was thus to conclude on the gas leak inspection programme and take the necessary actions.

Operations and results

Appraisal well 6407/9-6 R was spudded with the semi-submersible installation West Delta (now Deepsea Delta) on 19 May 1993. The gas leak had been observed to diminish during the inspection programme. Since it consisted almost exclusively of methane it was assumed to have originated from a minor shallow gas zone and not from the reservoir.

The well was plugged back and permanently abandoned on 30 May 1993.

Testing

No drill stem test was performed.
