History, Manufacturing, Reel and levelwind33:50
Trace the history of coiled tubing from World War II to the first injectors, then examine manufacturing processes, reel and levelwind systems, and surface equipment essentials.
Injector head, PCE, BHA31:22
Explore injector heads in coiled tubing, detailing gooseneck, hydraulic motors, sprockets, chain tension, and grabber blocks. Examine bahibak hydraulics, barriers, stripper types, and bottom hole assembly components.

Injector circuit basics37:07
Explore injector circuit basics by examining injector head motors, hydraulic pumps and controls, covering radial and axial piston motors, swashplate adjustment, speed control, brakes, counterbalance valves, and load sensing.
Injector circuit20:42
Injector mechanics30:49
Learn injector mechanics for coiled tubing, focusing on the forward chain system with gripper blocks, traction, and chain tension, plus gooseneck alignment and hydraulic ram controls.

CT forces23:22
CT Buckling23:17
Explore how coiled tubing buckling affects drag, weight on bit, and wellbore reach, including residual curvature, sinusoidal and helical buckling, and lookup limitations.
CT Stresses19:28
CT Fatigue18:43
Explore how alternating dynamic stresses lead to fatigue failure in coiled tubing, from crack initiation to propagation. Identify strategies to extend fatigue life, including gooseneck radius and internal pressure.

Pumping operation: Fill and scale removal29:24
Explore coiled tubing pumping operations, focusing on fill removal and scale removal, with attention to fluid rheology, jetting action, circulation methods, and operator safety.
Pumping operation: Acidizing11:29
Pumping operations: Cutting tubulars, Slurry plugs and N2 unloading10:15
Learn to cut tubulars with chemical and abrasive jet cutters, observe standoff and circulation, place cement, gypsum, sand, or polymer slurry plugs, and apply nitrogen unloading.
Mechanical operations overview6:01
Permanent installations: Reeled completions12:31
Explore permanent coiled tubing installations through read completions, velocity strings, and uniform outer diameter production conduits, with external offset components, injectors, and pre-assembled configurations.
Permanent installations: Offshore flowlines4:24
Explore offshore flowlines as permanent coal tube installations—vessel-laid, reducing installation time and costs by up to 55–75%, lowering pressure losses by 15–20%, and enabling subsea reel deployment.
Permanent installations: Casing and tubing repairs3:53
Contingency plan: stripper leak & leak above secondary barrier18:03
Explains coiled tubing well control contingency plans, detailing primary, secondary, and tertiary barriers, and step-by-step responses to stripper leaks and leaks above secondary barriers to maintain safety and operations.
Contingency plan: Leak below secondary barrier & Pinhole at surface or downhole10:55
Contingency plan: CT Parted at surface or downhole13:32
Develop a contingency plan for coiled tubing parted at surface or downhole by securing ends, evaluating check valves, and preparing for fishing operations with safety priorities.
Contingency plan: CT Stuck9:49
Discover how to define coiled tubing as stuck, identify causes and the three-point estimate, and apply up-down cycling, fluid displacement, friction reduction, and safe cutting or disconnect strategies before fishing.
Contingency plan: Runaway into the well or out of the well13:32
Contingency plan: Power-pack failure and reel motor failure8:22
Learn to manage power pack failure and reel motor failure in coiled tubing, applying failsafe brakes, injector brake, neutral positions, manual locks, and controlled recovery steps.
Contingency plan: Crane failure and working in injector with CT inside6:33
Cover contingency plans for crane failure and injector work with coiled tubing inside, detailing three failure categories and required security and repair steps.
Contingency plan: CT Collapse7:08

Description

Welcome to my course,

You will learn everything about coiled tubing operations.

This will incredibly increase your chance of any CT interview as this information only known by CT experts with many years of actual experience.

If you want to know anything beyond the scope of this course, contact me and I will send you training material and follow up with you.

During this course you will learn coiled tubing history starting from world war two then publications about development of injector concept till current model is introduced

Then you will learn CT manufacturing process.

After that you will learn surface unit components, PCE and BHA

In level two and three, you will learn all hydraulic circuits available in CT unit starting from introducing the concepts of hydraulics if you don’t know them.

In level four, you will know how to calculate CT forces and stresses, introduce the concept of CT buckling and lock-up and fatigue failure mode and how to minimize it.

In level five, you will learn pumping operations of CT then mechanical operations.

In addition, you will learn permanent installations of CT like reeled completions, offshore lines, etc.

Finally the most important part is contingency plans of operational and well control situations.
