During the last 15 years, coiled tubing applications have increased exponentially, with coiled tubing services continuing to be the fastest growing sector in the oilfield service markets. This has pushed the operators, service companies and manufacturers alike to work on advances in coiled tubing surface equipment, pipes, downhole tools, and wellhead equipment. At the same time, data acquisition and pipe integrity monitoring hardware and software have made the same significant advances.
All of this just does not happen in a short span of time and tens of millions of R&D dollars are poured in each year to continue to push the envelope of this ever-expanding market. But is there a step change required in the equipment we use today and in most cases used yesterday and even 15 years back? The size and weight of equipment has changed with most, but not all, getting larger to allow higher flow rates and the chance to get deeper and further out there.
It is intended in this session for the presenters and the participants to share their findings/advances and let everyone know what is around the corner for this exciting ever-changing business we work in. Does this well intervention method have another decade of growth and development, like the last decade?

Coiled Tubing Drilling (CTD) has been utilised on a commercial basis for many years, and can provide significant economic benefits when applied in the appropriate environment. The primary benefits along with potential cost savings are:
This session aims to explore the latest advancements in CTD through recent case histories along with the efficiencies and economics of CTD in the current market.

Energy demand is increasing worldwide with obliging operators expanding and opening up extreme and hostile fields. The subsurface operation becomes much more complex due to increase on pressure, temperature, and H₂S/CO₂ factors. Thus coil tubing string specs, equipment, procedures/techniques, and downhole tools are being continuously improved for safer, efficient, and economical operations.
This session will allow presenters and the audience to share their experiences of using coil tubing in extreme environments, highlighting any new methods/techniques/equipment pushing the limits beyond the traditional CT operating envelope. At same time it will provide an opportunity to deepen our understanding of the current CT constraints and what can be offered to aggressively unlock more reserves.

This session will focus on the advancements in the application of coiled tubing for efficient well intervention highlighting applications such as re-completion (straddle and velocity strings), horizontal and multi-lateral wells (CT access and reach), wellbore clean-out (debris, sand, scale, and filter cake), and well stimulation (CT acid wash, diversion, and matrix treatments). It also includes water/gas shut-off, and plug and abandonment operations that require services such as zonal isolation (cement, non-cement, and mechanical plugs); as well as mechanical applications (fishing, milling, and tubular cutting) where coiled tubing is ideal for efficient and effective operations.
With increased numbers of horizontal wells, more demanding wellbore complexity, harsher environments, higher temperatures and pressures, as well as maturing assets with lower bottom hole pressures, combined with the requirement for fewer trips and more efficient operations, the demands on coiled tubing, downhole tools, and service quality are always increasing. Innovation and the application of new techniques are important to push the working envelope, efficiency, and cost effectiveness of coiled tubing applications. The boundaries are continuously being pushed and as such coiled tubing applications need to evolve to a higher level to meet the increasingly demanding industry needs.
It is intended that the presenters and participants address these key factors and share their experience and advancements in techniques, best practices, and modelling that have been successfully utilised to increase production, extend well life, and reduce intervention and abandonment costs.

Unconventional resources will continue to grow in importance as a complement to conventional fossil fuel as world demand continues to increase. The mammoth volume and long-term potential of these energy resources are driving technical progress.
Economic exploitation of these resources caused dynamic technical and operational transformation in the oil and gas industry. To make these vast resources economically viable, the industry needed to overcome many critical challenges such as our ability to deliver the technologies necessary to unlock the global unconventional resources potential of more than 14,000 Tcf. For example, horizontal and hydraulically-fractured wells have been a key to unlocking the shale potential in North America, but are they the ideal technology in other parts of the world, and are they ideal for tight gas?
This session will attempt to address these questions and will discuss the innovative coiled tubing technologies that are used consistently in developing and producing these vital energy resources in the Middle East region and elsewhere.

Development within the CT industry in terms of materials, equipment, products, and the ingenuity to break down previous limitations, has resulted in a steady and impressive growth of CT and its applications.
If we believe in the predictions of further advancements and growth, along with the age demographics of our own members, and the current lack of skilled people in certain markets, it can be assumed, that if nothing changes, further deficiencies may be a reality.
This session is to discuss current and future ideas that will drive efficiency through technology and reducing personnel requirements at the well site along with the efforts to train the next generation of workers in our industry.
