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.

The papers summarized in this year’s feature demonstrate the application and versatility of coiled-tubing-based solutions to different phases of a well’s lifecycle, from exploration through production and, finally, to abandonment.
Intervention Work Flow Improves Injection Coverage in Tight Carbonate Reservoirs
The complete paper discusses an advanced matrix-stimulation work flow that brings reliability and flexibility to the acidizing of tight carbonate water injectors and has delivered injectivity improvements tight carbonate onshore reservoirs in the Middle East.
Testing Tool Conveyed by Coiled Tubing Enables Multiple Tasks in One Run
Some well-testing operations are executed by performing multiple runs in hole using slickline and coiled tubing (CT). A technology has been developed that combines many of these operations, including contingency stimulation activities, into one run.
