Hydraulic System Maintenance & Troubleshooting for Coiled Tubing

Learn to:

  • Interpret coiled tubing unit schematics
  • Think and act in a logical way when the system goes down
  • Conduct basic system tests
  • Analyze open and closed loop injector circuits
  • Analyze reel drag and traction circuit problems
  • Diagnose electric-over-hydraulic pump stroking problems
  • Follow correct system setup procedures

Would a deeper understanding of injector control and reel drag hydraulics help you with your troubleshooting?

This course is designed to be the first step in rigorous hydraulics training for coiled tubing operations and maintenance personnel. Participants come away from this highly concentrated course with a solid understanding of hydraulic principles, as well as component design and functions. System analysis and troubleshooting skills are taught using the circuits and schematics on a coiled tubing unit.

The Ten Step Troubleshooting Process is taught with the goal of eliminating the "hit or miss" methods that can be so costly in terms of time and materials. Safety is stressed along with sound maintenance practices. This three to five-day course is taught with circuit simulation software and through instructor guided hands-on study of individual hydraulic components.

The interactive, animated material is exceptional. It clearly illustrates CT functions and operation, and allows a visual interpretation of adjustments made to the system.Joseph A., Baker Hughes

Power Unit - CT Circuit Pumps

Objective: Identify the hydraulic pumps and their circuit functions

Activity: Locate the position of each pump on the tractor or skid based power unit

Sort out which power unit pump provides flow for particular coiled tubing functions

I really enjoyed learning about the P11P pump and also diagnostic techniques. The instructor explained everything in-depth and adapted well to operator questions.Josh P., Canyon Technical

Injector Circuit - Brake Functions

Objective: Identify critical fail-safe brake and functions

Activity: Interpret injector schematics and valve components
