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

Reservoir Descriptions and Dynamics

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.

Ron Zbitowsky is a Petroleum Engineering Consultant for Saudi Aramco. He joined Saudi Aramco in 1999 and is currently a Petroleum Engineering Consultant, specializing in all types of rig-less 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 his B.S. degree in Petroleum Engineering from Texas A&M University.  Ron is a licensed Professional Engineer in the State of Texas and is a member of the Society of Petroleum Engineers (SPE).

Todd Green is a Petroleum Engineering Specialist with Aramco Services Company. He started his career in the petroleum industry with BJ Services in 2006 as a field engineer in the Permian Basin in West Texas.  During these two years of field work, he personally attended 180 job locations.  He was chosen to lead a high-profile, high-pressure gas field project for a large independent producer in the Haley Gas field, which gave 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 as a desk engineer for Saudi Aramco.

In 2011, Todd joined Halliburton in a similar role working within Saudi Aramco.  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 joined Aramco Services in Houston to serve as coiled tubing subject matter expert.  In this current role, he assists with internal standards and manual revisions and teaches two courses 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 and has also co-authored 7 SPE papers on various CT well intervention topics. He holds a Bachelor of Science degree from Texas Tech University.
