Improvements in coiled-tubing (CT) data acquisition are sharpening the eyes and ears of downhole operations, as real-time data allows operators to better monitor operations from stimulation to drilling and conveyance. The versatile tubular continues to expand an already significant presence in well services and completions, and gyro-steering technology has opened opportunities to drilling applications in directional and horizontal wells. Over the past seven to eight years, a significant portion of Schlumberger research, engineering, and development funds has been invested in real-time downhole measurements, which includes the ACTIve family of live downhole coiled tubing services. To monitor pipe integrity and mitigate CT failures, Schlumberger has developed the CoilScan real-time CT pipe inspection system, which uses a magnetic flux leakage system that measures the CT’s mechanical and physical properties while running into the well, coming out of the well, and during the job.
