  1. Thermoflex Tubing for ESP Applications for the Oil and Gas Industry The use of reinforced polymer tubing with ESP’s to minimize cost and maximize productivity

  2. Benefits of Thermoflex Tubing for CBM Applications • 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 2ft/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. Improved Corrosion Resistance vs. Steel • Oil/Gas/CO2/Brine Nylon • H2S or High Temp (250F) Fortron (PPS) • No Polyethylene Service Life in H2S Environment Source: Merl Test Lab

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

  7. 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

  8. 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

  9. 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

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

  11. 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

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

  13. Installation Equipment

  14. Attaching the Pump

  15. Banding The Cable To The Tubing • Rubber or Tape Under Bands • Plastic on Metal Slips • Holds Items Prior to Banding • Band Every 50ft • 500lb or less Compression Load

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

  17. Installation Timing • 40Minutes for 1,800ft Well after Splice • If Pulling Pump lift cable at same rate • Can’t Spool Cable and Tubing Together

  18. Why it Works • 1” Thermoflex . . . 1/2bbl Fluid per 1,200ft • Velocity Lifts Solids • Size vs. Fluid Flow • 1” . . . 250bbl/day • 1.25” . . . 600bbl/day • 1.5” . . . 1,500bbl/day
