Abstract: A larger diameter coiled tubing is run into an extended reach deviated wellbore to a location at or near its horizontal reach limit. The smaller diameter coiled tubing is then run through the larger diameter tubing until the end of the smaller tubing protrudes from the larger tubing. The smaller tubing is then run further into the wellbore to a location further than would have been possible if either tubing had been run alone. Supplementary reach-increasing techniques such as friction reducing vibrators and/or downhole tractors can also be used in combination with the described techniques.

A sensor is positioned to monitor a pipe for a magnetic flux leakage signal indicating a defect in the pipe. The sensor outputs data on the magnetic flux leakage signal to a data processing system.
