  • 1. A Brief Introduction to Coiled Tubing What is it? What do we do with it? Li Gao, PhD Research Department Halliburton
  • 2. Outline
    • Halliburton Company
    • Coiled Tubing history
    • What is it? Equipment
    • What do we do with it? Applications
    • PE vs. MD
  • 3.
    • Funded in 1919
    • Offers the world's broadest array of products, services and integrated solutions for oil and gas exploration, development and production.
    • $35B market cap, $22B revenue in 2006
    • Employs 100,000 people in more than 120 countries
    Halliburton Company
  • 4. CTAT Time Line Coiled Tubing History: Military Origin
    • D-Day, Pluto Project
      • P ipe L ine U nder T he O cean
      • British engineers developed long, continuous pipeline to supply Allied forces
      • Twenty-three 3” pipelines across the English channel
      • 30 to 70 miles long
      • Fabricated from 4000’ sections, Butt welded together
  • 5. Coiled Tubing History: Military Origin
    • Submarines
      • Antenna Deployment System
        • Developed by Bowen Tool
        • Deployed 5/8” polyethylene antenna to surface from submerged submarine
        • Packer device to seal around antenna
      • Evolved into Coiled Tubing Injector Head
  • 6. 1st Coiled Tubing Work in the Oilfield
    • California Oil Company, 1962
    • Bowen Oil Tool fabricated reel and equipment
      • Reel: 1.315” O.D. Pipe, 50’ sections butt welded, 15000’ total length
      • Used for washing out sand bridges on oil and gas wells
  • 7. Coiled Tubing Unit Tubing Injector Tubing Guide Reel Control House Well Control Equip. Crane Power Pack Stripper
  • 8. Tubing
    • Steel pipe 1” OD to 3.5” OD
    • Yield strengths of 70,000, 80,000, 90,000, 100,000 psi
    • Relatively thin wall
    • Finite life due to fatigue cycles (bending)
  • 9.
    • Hydraulically powered counter rotating chains
    • Gripper blocks mounted in chain assembly
    • Injector designation based on maximum pull capability, e.g 30K can pull 30,000 pounds
    Injector
  • 10.
    • Guides tubing into injector
    • Large radius for best tubing life
    Tubing Guide (Guide Arch)
  • 11.
    • Used to store tubing
    • Large radius for best tubing life
    • Level wind assembly to wrap tubing on and off reel
    Reel
  • 12.
    • Operator station for unit control
    • Typically mounted behind reel
    Control House
  • 13. Coiled Tubing: What do we do with it?
    • Uncoiled into live oil and gas wells to perform maintenance operations
      • placement of chemicals
      • cleaning
      • manipulation of mechanical tools
      • milling / drilling
      • logging / perforating
  • 14. CT Applications
    • For vertical, horizontal and deviated wells, both on land and offshore:
    • Drilling
    • Logging
    • Perforating
    • Stimulation
    • Fluid displacement
    • Sand control
    • CT conveyed perforating
    • Wellbore cleanout
    • Remedial cementing
    • Setting and retrieving bridge plugs
    • Permanent installations
    • Running packers
    • CT as flowline
    • Removal of wax, hydrocarbon or hydrate plugs
    • Flow control of horizontal and deviated completions
    • Fishing
  • 15. A Comparison between …
    • Sand, hydrates, etc. deposits
    • Cholesterol plaque built up
    • Well intervention
    • Percutaneous Coronary Intervention (PCI)
    PE’s world MD’s world
