Abstract

Intervention operations using coiled tubing (CT) continue to be one of the fastest growing segments of the oil and gas industry. Over recent years, global shale exploration has demanded the need for continuous advances in technology to reach deeper, faster, more efficiently, and with the least amount of non-productive time.

The topic of this paper is specific to extended reach technology, and explains how an innovative tool that generates pressure pulses and transmits axial vibrations along the CT will improve weight transfer, reduce CT to wellbore friction, allow for more efficient CT applications, and allow CT intervention to reach depths not otherwise possible with conventional tool strings.

Case histories have shown that this proven technology has allowed CT operations to achieve significantly better results than anticipated. The technology has allowed for successful intervention and expanded the operating window of coiled tubing assemblies, ultimately resulting in a greater return on investment for the operator.

Continued need for robust technology with high durability and shorter tool length continues to be key for all new CT tool designs. Therefore, as coiled tubing intervention continues to move into more technically challenging areas, it is crucial that the industry learn from today and continue to engineer for tomorrow.
