Session 1: Coiled Tubing Equipment and Manufacturing
Session Chairpersons Kerry Quick, NOV; Tarek Shaheen, Quality Tubing

Over the last two decades the oil and gas industry has witnessed continued technology innovations in conjunction with coiled tubing use. The impact of operation failures during the execution of these high–technology coiled tubing interventions has become more critical.

To control and mitigate these concerns several successful initiatives have been introduced to reduce the risk of coiled tubing pipe failure while performing interventions in oil and gas wells. Through the use of every increasingly accurate computer modelling, the industry has seen a marked reduction in the number of pipe failures. Similarly, through the use of continually upgraded and improved surface equipment and PCE, the industry has seen a marked reduction in the number of operational incidents.

This session will shed some light and update participants on the latest technologies in the follow presentations.

Session 2: Stimulation and Placement
Session Chairpersons Fernando Baez, BRVR Consultants; Wassim Kharrat, OiLSERV

Coiled tubing stimulation is the preferred practice when operators are aiming to pinpoint chemical treatments across the zones of interest, or when protecting wellbore tubulars from live acid and harsh chemicals. When combined with mechanical and/or chemical diversion techniques, coiled tubing stimulation becomes an excellent choice; especially for extended reach wells, large contact area reservoirs, and multilateral wells.

The major challenges for these coiled tubing stimulation jobs, besides the candidate selection and damage identification, is the design and placement of treatment fluids and especially the diversion.

This session aims to capture best practices and recent case studies where service companies share their innovative procedures and technologies that resulted in successful coiled tubing stimulation.

Session 3: Coiled Tubing Downhole Tools
Session Chairpersons Noor Alenezi, Baker Hughes, a GE company; Alex Osorio, IPI

As market trends in the oil and gas industry call for cost-effective well intervention methods, today’s operational challenges and economic climate are the main drivers behind current technological advancements and operational improvements throughout the oilfield. The exponential growth and diversification of downhole tool technology leads to significant impact in expanding the applications of coiled tubing operations. Innovative downhole tools carry advanced solutions, enhance production, and increase coiled tubing capabilities while reducing operational intervention time. Likewise, cutting-edge developments of downhole-tool metallurgy and elastomeric materials are also attributed to pushing the envelope and contributing to well intervention growth. This session presents emerging downhole tool technologies, and discusses relevant case studies to share experiences in order to promote the value of well intervention solutions within the oil and gas industry.

15:30 - 16:30
Session 4: Extended Reach
Session Chairpersons Abdullah Al-Qasim, Halliburton; Kevin Elliot, NOV

Wells with extended read drilling have become increasingly common for the past decade with extended reach wells being typical for many fields around the world. The economic benefits of extended reach wells in terms of minimising drilling time while maximising reservoir contact are now well established.  Frequently, the limiting factor for extended reach wells is the reach of the coiled tubing rather than a limitation for drilling. Therefore, the challenge is clear: ensuring that coiled tubing can work in wells with long laterals for both completions and interventions.

This session will examine available and theoretical technologies including coiled tubing string design, chemical friction reduction, and mechanical means of extending the reach. Presenters will showcase the best available technologies (or combination of technologies) supported by field case studies and dynamic modelling.

Session 5: Coiled Tubing Drilling
Session Chairpersons Hussain A. Quwaisim, Saudi Aramco; Sylvain Prossaird, Schlumberger

The techniques and equipment associated with coiled tubing drilling (CTD) have undergone rapid development since the first operations attempted in 1991. A principal stimulus for this activity was the availability of increasing coiled tubing pipe size.

The safety advantage brought by CTD equipment and workflow enabled underbalanced drilling operations using the existing completion in order to perform sidetracking operations. CTD is now providing the ability to unlock new reservoir, while preserving the reservoir matrix.

This session will discuss the recent advances and developments in CTD practices and BHAs in addition to illustrating successful achievements.

10:30 - 12:30
Session 6: Artificial Lift
Session Chairpersons Anas Obeidat, Tenaris; Sonny Sola, Nordic Energy

Coiled tubing has been used in oil and gas operations for many years and has proven to be an efficient, reliable, and economic tool. The coiled tubing technology has been utilised for drilling, completions, workover, stimulation, plugging, and abandonment work for decades, with considerable success. Coiled tubing for use in artificial lift operations has been somewhat limited, but in the economic environment that exists today, new opportunities have been recognised. Presentations will describe the new developments in artificial lifting with coiled tubing.

12:30 - 13:30
13:30 - 15:00
Session 7: Production Enhancement with Coiled Tubing
Session Chairpersons Pierre Fize, ArcelorMittal; Kerry Quick, NOV

Coiled tubing has established proven records of improving production enhancements techniques, especially in critical environments (sour, offshore, and, deep directional shale wells).

The beauty of this is that coiled tubing has been bringing decisive technical advantages while offering a cost advantage to the service companies. This is, therefore, no surprise that coiled tubing has remained a very popular tool during the recent energy depression and is, more than ever, the key partner for the shale industry.

More specifically in the Middle East, coiled tubing has been a unique equipment to achieve the highly demanding local challenges for both onshore and offshore applications.

This session will present recent examples of production enhancement cases using coiled tubing as a key support tool.

15:00 - 15:30
15:30 - 16:30
Session 8: Deployment Opportunities with Coil Tubing
Session Chairpersons Chris Kuijken, AlMansoori Petroleum Services; Tarek Shaheen, Global Tubing

Coil tubing has a huge range of deployment applications that will benefit the “ease” of deployment and ability to intervene complex work in a rig-less manner.

One example is excessive water production which remains one of the greatest challenges that are faced in the oil and gas Industry—as it creates inefficiencies in the production process from production tubing into the processing facilities

Coiled tubing technology is a powerful enabler to manage this undesired “water challenge” and recent developments comprise a wide range of water-shut off-technologies (cladding and chemicals) and even deployment of down-hole technologies for water separation. In the wider context coil tubing is used as a lower cost replacement for most of the capabilities used in well intervention operations including milling, fishing, drilling, perforating, as well as data acquisition for reservoir monitoring and analysis.

This session will cover any coiled tubing deployed technology or capability that is not covered in any of the previous seven sessions in order to ensure during this SPE event nothing is missed out and no opportunities get lost for learning and sharing.
