Advanced Coiled Tubing Engineering and Best Practices

Disciplines: Production and Operations

Course Description

This seminar will begin with a very brief review and refresher of basic CT equipment and well control components. The remainder and primary focus of the seminar will be on job design consideration, safety considerations, and job execution of common CT intervention job types including:  Nitrogen lifting, Proppant or fill cleanout, Milling, Acid Stimulation, logging, and perforating.

Upon completion of this course, participants will be able to:

  • Recognize and explain function of CT surface equipment
  • Recognize and explain function of PCE and BHAs
  • Identify and describe critical job design considerations for each job type that should be present in a contractor CT job proposal
  • Discuss risks associated with each CT intervention and the corresponding mitigation controls recommended for each job type
  • Optimize the CT intervention efficiency and success by applying industry best practices and lessons learned for each job type
  • Attend and assess ongoing CT intervention’s  success at the wellsite for each job type

Course Length

1 Day

Why Attend

You should attend this seminar to expand your knowledge of coiled tubing applications and engineering design considerations that can directly affect your operations both positively and negatively.  There are great cost savings to be realized when CT interventions are conducted safely and efficiently.  Equally, poorly understood and planned CT interventions create costly and sometimes dangerous problems during a CT intervention.  These issues can be avoided with the knowledge, best practices, and lessons learned provided in this short seminar.

Who Attends

This seminar is designed for engineers, senior operations personnel, and company representatives with previous basic CT knowledge who are assigned to utilize coiled tubing in their operations.

Special Requirements

Computer is optional but would be beneficial as the participants may wish to view resources that the instructor will share.


0.8 CEUs (Continuing Education Units) will be awarded for this 1-day seminar.

Todd Green, taught Physics and Chemistry for 8 years, then started his career in the petroleum industry with BJ Services as a field engineer in the Permian Basin field of West Texas. Todd was responsible for designing, attending, and evaluating CT operations of four CT units. During these two years of field work, he personally attended 180 job locations. As a result of his expertise, he was chosen to lead a high profile high pressure gas field project for a large independent producer in the Haley Gas field giving him a wealth of experience in high pressure high temperature gas field operations.

In 2008, Todd took an international assignment as senior coiled tubing engineer supporting all CT intervention in the southern area of Saudi Arabia for BJ-Baker Hughes. Saudi Aramco requested that Todd be assigned as a desk engineer to better support Aramco’s expanding high pressure gas operations. Todd served in this role until 2011 before joining Halliburton in a similar role.

In 2012, Todd was promoted to Account Representative for Halliburton and continued to support Saudi Aramco with CT and stimulation interventions. During this time, Todd was project lead and design engineer for the first in Kingdom implementation of a CT velocity string installation below the tree utilizing a custom made hydraulic set CT packer. This job became an example for the industry and the procedures for this type of operation are now included in the Saudi Aramco CT Manual.

In 2014, Todd took a position with Aramco Services in Houston to serve as coiled tubing subject matter expert as part of a multidisciplinary Upstream Technical team. In this role, he assists with internal standards and manual revisions and teaches two seminars for Saudi Aramco’s Upstream Professional Development Center in Dhahran: CT Applications; CT Job Design and Evaluation.

Todd has experience designing and implementing a variety of CT interventions that include: Foam cleanouts, High angle cleanouts, CT high rate acid stimulations, Milling with CT, fishing Operations, CT e-line logging, Velocity string design and installation, Cementing with CT, Mechanical de-scaling, Utilizing multilateral seeking tools, Nitrogen lifting, Abrasive perforating with CT, and various drilling rig assist operations. Todd has also co-authored 6 SPE papers on topics that include: Case Study for Milling with CT in High Pressure Gas Wells, CT cleanouts and best practices, Cleanout efficiency and economics case study, Extended Reach CT Logging interventions, and HPHT Mechanical Descaling in Extreme Environments.
