Introduction

This course covers the coiled tubing applications. Economics and improvements in tools and technology have greatly increased the sphere of coiled tubing applications.  Coiled tubing is the completion and remedial work string of necessity in many wells, especially for offshore, horizontal, and multilateral wells.  But coiled tubing is not a panacea; there are many limitations, some obvious, some not.  The questions most operators ask about this advancing technology are:

What can be done with coiled tubing today that could not be done a few years ago? 

When should coiled tubing be used? 

When should coiled tubing not be used? 

 

This course is packed with the kind of information needed to answer those questions and to intelligently plan and carry out successful coiled tubing operations for specific applications.  The course covers fundamental characteristics and properties of coiled tubing and how they affect well operations. 

 

Most of the course is devoted to the all-important practical applications in completions and production operations including case histories.  This objective and practical course is presented with operating personnel in mind so that they are equipped to decide when, how, and whether or not to employ coiled tubing technology.

Objective

By the end of this course, participants will be able to:

  • Describe the fundamentals of coiled tubing and specify related equipment
  • Determine the parameters of coiled tubing failure and how to minimize failures
  • Plan safe and effective coiled tubing operations
  • Specify coiled tubing procedures and equipment for production applications
  • Specify coiled tubing procedures and equipment for completion applications
  • Analyze case histories of coiled tubing successes and failures
  • Well intervention operations and trouble shooting
Audience

New recruits engineers who are following Reservoir Engineering Development framework
