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


Benefits of thermoflex tubing for cbm applications
Benefits of Thermoflex Tubing for CBM Applications Industry

  • Sized to Lift Solids without Excessive Pressure drop

  • Corrosion Resistance

  • Ease and Speed of Installation

  • Suitable for Water/Oil/Condensate

  • Lightweight Tubing Protects Cable


Requirements to lift solids
Requirements to Lift Solids Industry

  • Liquid Velocity Greater than 2ft/sec

  • Plastics Reduce Pressure drop vs. Steel.

  • Must Dispose of Solids at Surface


Reduced pressure drop
Reduced Pressure Drop Industry

  • Surface Roughness

    • Steel . . . .005

    • Nylon . . . .00005

  • Increased Velocity Increases Pressure Drop

  • Polymers 50% Lower Pressure Drop at Greater Velocities


Improved corrosion resistance vs steel
Improved Corrosion Resistance vs. Steel Industry

  • Oil/Gas/CO2/Brine Nylon

  • H2S or High Temp (250F) Fortron (PPS)

  • No Polyethylene

Service Life in H2S Environment

Liner construction design
Liner Construction & Design Not Available From Polyethylene (PE)

  • 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


Reinforced design and construction
Reinforced Design and Construction Not Available From Polyethylene (PE)

  • 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


Couplings and terminations
Couplings and Terminations Not Available From Polyethylene (PE)

  • Couplings Swedged on Both Ends

  • Duplex Stainless or Zinc Chromate Plated Carbon Steel

  • Any Thread or Connection Available

  • Swedged in the Field or Plant


Portable coupling machines
Portable Coupling Machines Not Available From Polyethylene (PE)

  • 1” to 4.5” Couplings

  • Hand Pump or Enerpac


Modeling wells for optimal tubing size
Modeling Wells for Optimal Tubing Size Not Available From Polyethylene (PE)

  • Tubing Sized for Fluid Velocity (bbl/day vs ft/sec)

  • Pressure Drop Curves to Determine Dynamic Head

  • Dynamic Head for Sizing Pump


Installation
Installation Not Available From Polyethylene (PE)

  • Continuous Tubing

  • Direct Drive Spooling Truck

  • Cable Banded to Tubing

  • Hang off with Tubing Hanger or Stuffing Box


Installation equipment
Installation Equipment Not Available From Polyethylene (PE)


Attaching the pump
Attaching the Pump Not Available From Polyethylene (PE)


Banding the cable to the tubing
Banding The Cable To The Tubing Not Available From Polyethylene (PE)

  • Rubber or Tape Under Bands

    • Plastic on Metal Slips

    • Holds Items Prior to Banding

  • Band Every 50ft

  • 500lb or less Compression Load


Hanging off
Hanging Off Not Available From Polyethylene (PE)

  • Utilize Steel Tubing Hangers, Stuffing Box

  • Cable Pack Off

  • Tubing Lightweight Protecting Cable from Abrasion


Installation timing
Installation Timing Not Available From Polyethylene (PE)

  • 40Minutes for 1,800ft Well after Splice

  • If Pulling Pump lift cable at same rate

  • Can’t Spool Cable and Tubing Together


Why it works
Why it Works Not Available From Polyethylene (PE)

  • 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
