It has been said that there is nothing new under the sun, which, if true, would imply that, in a mature industry such as ours, there is little opportunity for innovation or original thought. Another oft-quoted idiom is “to think outside the box,” which raises the questions for me of “What box?” and “Who keeps making these boxes?” Are we really in an industry that is so mature that it is devoid of new thoughts and incapable of generating new concepts to meet the challenges that we face?
I would contend not. The coiled-tubing industry has always been defined by energetic and innovative people meeting the new challenges they encounter. Today is no exception. Wells in which coiled tubing is used have become deeper, have longer horizontal sections, have higher pressures, and are less accessible because of platform and crane limitations. The recent SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition held in The Woodlands, Texas, showcased varied solutions, both in the exhibition hall and in the technical sessions. Innovative downhole tools; newer, stronger materials; new fluid additives; improved equipment; software improvements; and a deeper understanding of fundamental mechanics were among the many progressive steps being shared with attendees. Older techniques that had been rethought and applied to today’s issues were also presented.
Another aspect of the conference that has been gratifying to see over the past few years has been the larger proportion of new and younger attendees. This new cohort brings with it its more-current view of the world. The challenge for the older generation is to be open to the different visions of the newer generation. Maybe certain solutions have been tried in the past and found wanting. However, the use of more-current technologies, such as high-power digital data communication and processing power, brings new possibilities.
The can-do attitude and spirit of innovation in the coiled-tubing segment of the oil and gas industry are still vibrant. It is all too easy to be cynical and to pigeonhole people’s efforts in our current sound-bite world. So, perhaps we, as individuals, have to be vigilant not to remain in our self-constructed boxes.

Coiled-Tubing Telemetry Intervention in Shut-In Conditions
When a new horizontal well in Asia was incapable of unassisted flow, coiled tubing (CT) was selected for the perforation and stimulation intervention. Mechanical isolation was required to ensure that the stimulation fluids entered only the new zones.
Isolation Barriers With Coiled Tubing in Plug-and-Abandonment Operations
Plug-and-abandonment (P&A) operations can be expensive, leading to negative net present value. Historically, P&A operations in the North Sea—estimated to hold some 3,000 wells of declining production—were performed with either drilling or workover rigs.
Underbalanced Drilling With Coiled Tubing in Marginal Shallow Wells
The complete paper describes a recent directional coiled-tubing drilling (DCTD) job completed for an independent operator in the Appalachian Basin.
