Coiled Tubing: From Conventional to Advanced Applications

9 – 11 September 2013

Limassol, Cyprus | Le Meridien Resort and Spa

Technical Agenda

Session 1: Introduction to Coiled Tubing

Session Chairs: Ahmed Azab, SAPESCO; Ali Mazen, Schlumberger

Over the past decade coiled tubing applications have increased exponentially as coiled tubing services continued to be the fastest growing sector in the oilfield industry. This, consequently, drove huge growth in the demand for advanced coiled tubing surface equipment, pipe, down hole tools, wellhead equipment, and pipe integrity monitoring hardware and software.

Coiled tubing manufacturers, suppliers, and service providers work very hard to meet this increasing demand through large investments in research, engineering, and development of advanced technologies, techniques, tools, procedures, fibre optics, and real-time monitoring for both conventional and non-conventional coiled tubing applications and environments.

Session 2: Coiled Tubing Drilling

Session Chairs: Gary Cavanough, CSIRO; Kerry Quick, NOV

Coil tubing has traditionally been used for intervention activities in existing wells. The use of coil tube drilling (CTD) is a newer technology. The industry has developed from a state of no holes being drilled with CTD in 1992 to around 800 holes in 2002. Since 2002, it has seen an increase of around 1,000 holes per year up to 4,500 holes in 2006 and more in recent years. Applications include oil, shale, and coal seam gas (CSG). CTD is also being applied to the mining industry due to productive and safety gains because there is no rod handling. 

This session focuses on the “drilling” aspects of CTD and the session presentations are:

Session 3: Coiled Tubing Production Enhancement Application

Session Chairs: Rashad Zahrani, Saudi Aramco; Gaby Haddad, Baker Hughes

Coiled tubing applications are developed and implemented in order to maximize recovery in a cost-effective manner. These applications have gotten more sophisticated in order to address the new and more complex wells being drilled such as ERD wells.

This session focuses on the applications for coiled tubing to enhance well productivity. The four main topics in this session relate to formation stimulation, zonal isolation, logging and perforation as well as advanced techniques for ERD wells with emphasis on the value added. These applications have been enhanced with new technologies like DTS to monitor the treatment efficiency. Such technologies enabled realizing significant improvement in the success rate as well as production gain from well interventions.

This session will examine case histories as well as new and innovative applications of coiled tubing to improve production in a safe, timely and cost-effective manner. Presenters are urged to focus on advanced applications in order to maximize the knowledge and help share best practices industry-wide.

Session 4: Non-Conventional CT Application

Session Chairs: Ali Shidhani, Petroleum Development Oman; Saif Takash, Halliburton

As the worldwide demands on the oil and gas industry increase, operators are attempting to maximise the recovery of hydrocarbons from more and more complex wells. These complex wells are in existing and/or depleted reservoirs, thus coiled tubing applications like other well interventions, tools, and methods have gone through significant advancements covering the wide range of traditional applications and extended them to new applications. Non-conventional CT applications cover wide ranges of applications, but are not limited to data gathering, production enhancement, and CT remedial interventions.

The session will allow presenters and the audience to share their experiences of using non-conventional CT applications and address new methods and techniques that will push the boundaries of what is traditionally achievable with coiled tubing. Such non-conventional CT applications can unlock trapped hydrocarbons in depleted reservoirs, shut-in wells, or enhance production from complex reservoirs which will result in a better return on investment.

Session 5: Coiled Tubing Workover/Advanced Conventional Applications

Session Chairs: Ian Smith, Weatherford; Mansour Shaheen, Baker Hughes

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, down hole tools, and service quality are always increasing.

This session will focus on the advancements in the application of coiled tubing for efficient well remediation highlighting but not limited to 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). Late stage intervention and plug and abandonment operations also require services such as zonal isolation (cement, non-cement, and mechanical plugs) and mechanical applications (fishing, milling, and tubular cutting) where coiled tubing is ideal for efficient and effective operations and the provision of solutions to the challenges faced.

Innovation and the application of new techniques are important to increase 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 ever more 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 has been successfully utilised to increase production, extend well life, and reduce intervention and abandonment costs.

Session 6: Coiled Tubing—The Way Forward

Session Chair: Hatem Saggaf, Saudi Aramco

Currently innovative intervention services conveyed on coiled tubing (CT) are designed to improve wells, reservoir performance, efficiency, and results of (CT) operations in various types of well configurations. Operators and service companies worldwide use coiled tubing for a range of tasks that would have been inconceivable only a few years ago. Large diameter coiled tubing and the availability of hardware needed to handle it became more widespread and more services were in demand. Therefore, upgrading existing tools and techniques while developing new technology remain key factors for the future success of coiled tubing. This session will explore the future of (CT) applications and the services to be enhanced to meet existing and future challenges.
