  1. Thermoflex® Tubing for ESP Applications for Well Deliquification 3rd European Conference on Gas Well Deliquification September 15-17 Groningen The Netherlands

  2. Benefits of Thermoflex Tubing for CBM Applications with ESPs • Sized to Lift Solids without Excessive Pressure drop • Corrosion Resistance • Ease and Speed of Installation • Suitable for Water/Oil/Condensate • Lightweight Tubing Protects Cable

  3. Requirements to Lift Solids • Liquid Velocity Greater than 0.6m/sec • Plastics Reduce Pressure drop vs. Steel. • Must Dispose of Solids at Surface

  4. Reduced Pressure Drop • Surface Roughness • Steel . . . .005 • Nylon . . . .00005 • Increased Velocity Increases Pressure Drop • Polymers 50% Lower Pressure Drop at Greater Velocities

  5. New Engineered Plastics Provide Higher Temperature Strength Not Available From Polyethylene (PE) Fortron Capron PE

  6. Liner Construction & Design • Multi-layer Design • Inner Layer for Corrosion Resistance, Low Permeation and Higher Temp Strength . . . Nylon and Fortron • Outer Layer for Higher Temperature Strength, Abrasion Resistance • Fully Bonded • Applications to 250F Inner Barrier Outer Strength and Abrasion Layer

  7. Reinforced Design and Construction • Reinforcement Provides All of the Strength • Cross Braids for Burst • Longitudinal Braids for Stretch Resistance • Aramid Fibers for Low Elongation • Tubing Strength P=(2*F*n)/D*L

  8. Couplings and Terminations • Couplings Swedged on Both Ends • Duplex Stainless or Zinc Chromate Plated Carbon Steel • Any Thread or Connection Available • Swedged in the Field or Plant

  9. Portable Coupling Machines • 1” to 4.5” Couplings • Hand Pump or Enerpac

  10. Modeling Wells for Optimal Tubing Size • Tubing Sized for Fluid Velocity (bbl/day vs ft/sec) • Pressure Drop Curves to Determine Dynamic Head • Dynamic Head for Sizing Pump

  11. Installation • Continuous Tubing • Direct Drive Spooling Truck • Cable Banded to Tubing • Hang off with Tubing Hanger or Stuffing Box

  12. Installation Equipment

  13. Attaching the Pump

  14. Banding The Cable To The Tubing • Rubber or Tape Under Bands • Plastic on Metal Slips • Holds Items Prior to Banding • Band Every 15mt • 225kg or less Compression Load

  15. Hanging Off • Utilize Steel Tubing Hangers, Stuffing Box • Cable Pack Off • Tubing Lightweight Protecting Cable from Abrasion

  16. Installation Timing • 40Minutes for 549m Deep Well after Splice • If Pulling Pump lift cable at same rate • Can’t Spool Cable and Tubing Together

  17. Size versus Fluid Volume • 1” Thermoflex . . . 0.07m3/366meters • Velocity Lifts Solids • Size vs. Fluid Flow • 1” . . . 250bbl/day (33.7m3/day) • 1.25” . . . 600bbl/day (81m3/day) • 1.5” . . . 1,500bbl/day(203m3/day)
