Repeated plastic bending of coiled tubing (CT) on/off the reel and gooseneck make CT fatigue failure a serious concern, especially when combined with internal pressure. CTLIFE predicts CT failure via a low-cycle fatigue mechanics model and statistical data developed by Halliburton. Consumed CT life is predicted after every operation. The program is suitable for any CT operation, both on- and offshore.

Advanced Engineering Features
- Models repeated bending of CT on the reel and gooseneck as it impacts fatigue life
- Accounts for CT internal pressure
- Handles CT strings with up to 15 different ID sections
- Allows different internal pressures for trips in and out for different well depths
- Consumed life is animated for different operations
- Simulates "weight-checking" pick-up routines
- Accounts for corrosion and stress concentrations at butt-welded sections
- Predicts total strokes to failure
- Sensitivity analysis on CT OD, grade, wall thickness, weld types, and fluid corrosion
- Updates current CT life for the next run
- Includes extensive CT database
Cost Saving
- Helps prevent costly CT failures
- Eliminates guesswork and is more cost-effective than applying simple (overly conservative) rules of thumb
- Enhances operational efficiency
Easy to Use
- Step-by-step problem solving approach

Reel and rig geometry have a critical impact on CT life.
CTLIFE tracks the amount of life consumed during a run and can be used at the job site.
