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

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

• Interpret coiled tubing rig schematics.
• Think and act in a logical way when the system goes down.
• Conduct basic system tests.
• Analyze injector hydrostatic drives.
• Diagnose ‘electric-over-hydraulic’ pump stroking problems.
• Follow correct system setup procedures.
