Since the Arbroath platform is a rigless platform, a full workover was considered a costly operation with prohibitive lead times. For that reason less costly and innovative through tubing repair options were considered to allow the well to be returned to production. After considering several options a coiled tubing straddle insert was chosen as the prefemed repair method to meet the success criteria for the job.The straddle consisted of 3 1/2" coil with hydraulic set packers at either end and was successfully run inside the existing 4 1/2" completion to seal off the corroded section of tubing allowing the well to return to production. This paper describes the repair options considered, the design, planning and installation of the coiled tubing straddle and the subsequent post repair well results.
