Rigless Intervention Best Practices for Coiled Tubing, Slickline, and Wireline


Disciplines: Reservoir

Course Description

This short course is designed to provide knowledge and understanding of surface equipment, downhole tools, various applications, and operational contingencies for rigless well interventions involving coiled tubing, slickline, or wireline.  The participants will learn first-hand knowledge of the capability of each intervention and what to consider when choosing which intervention method to utilize.  The course will cover recommended risk mitigation and well control barriers as well as best practices gained from years of experience and application.  To further illustrate the intervention methods utilized to resolve well issues or enhance well performance, real world examples for coiled tubing, slickline and wireline will be presented and discussed.

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

  • Recognize and explain function of CT, Slickline, and wireline equipment
  • Recognize and explain function of the Pressure Control Equipment and Bottom-hole assembly’s for coiled tubing, slickline and wireline interventions.
  • Identify common applications for coiled tubing, slickline, wireline interventions
  • Assess the pros and cons of each intervention and evaluate which intervention type to utilizes for various job problems
  • Identify and describe critical job design considerations for each job type of intervention that should be present in a contractor proposal
  • Discuss risks associated with each each type of intervention and the corresponding mitigation controls recommended for each job type.
  • Enhance rigless intervention safety, efficiency, and success by applying industry best practices and lessons learned for each job type.

Why Attend

Poorly understood and inefficiently planned rigless interventions can create costly, and often dangerous, problems for operators. These issues can be avoided with the knowledge, best practices, and lessons provided in this short course.

Attendees of this course will benefit from the increased knowledge of rigless, live well interventions including coiled tubing, slickline, and wireline. In addition, course attendees will review engineering design considerations, recommended safety policies, and best practices that can positively affect operations.

Who Attends

This course is designed for engineers, senior operations personnel, and company representatives with zero-to-intermediate well intervention knowledge who are assigned to evaluate, plan, and/or execute coiled tubing, slickline, or wireline interventions. 

Special Requirements

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

Ron Zbitowsky is a petroleum engineering consultant for Saudi Aramco. He joined Saudi Aramco in 1999 specializing in rigless well intervention. He works in the technical support unit of the Ghawar gas production engineering division in Udhailiyah, Saudi Arabia.  Ron has 34 years of combined experience in drilling, reservoir, pipeline and production engineering in both conventional and unconventional natural gas reservoirs.  Prior to joining Saudi Aramco, Ron worked for various exploration and production companies operating in the United States primarily in South Texas, Louisiana, Alabama as well as West Texas and New Mexico. In 1982, he received a BS in petroleum engineering from Texas A&M University.  Ron is a licensed Professional Engineer in Texas and is a member of the Society of Petroleum Engineers (SPE).

Steven Craig is a global technical manager in the coiled tubing product line of Baker Hughes. Prior to his current technical leadership role, Mr. Craig held several engineering and technical instructor positions during his 29-year career with Baker Hughes and legacy companies (BJ Services and Nowsco Well Service) in the UK, Norway and Germany.

Mr. Craig is active in SPE/ICoTA, has co-authored more than 30 technical papers, served multiple times on the committee for this conference and was chair in 2015. Additionally, since 2006 Mr. Craig has been active in the API RP 16ST (Coiled Tubing Well Control) committee. Mr. Craig holds a Bachelors degree in Mechanical Engineering from Heriot-Watt University Edinburgh and is registered as a chartered engineer with the Engineering Council in London and member of the Institution of Mechanical Engineers.

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.
