Cut and Thread, Cut and Thread Fishing Technique
Cut and thread is a fishing technique for recovering wireline stuck in a wellbore. In cut and thread operations, the wireline is gripped securely with a special tool and cut at the surface. The cut end is threaded through a stand of drill pipe. While the pipe hangs in the wellbore, the wireline is threaded through another stand of drill pipe, which is screwed onto the stand in the wellbore. The process is repeated until the stuck wireline is recovered.
