Thermoflex® Tubing

Reinforced Thermoplastic Gathering, Disposal and

Injection Lines

Overview June 11, 2012

Polyflow LLC

• Design Manufacture and Market Reinforced Thermoplastic Pipe and Tube for the Oil and Gas Industry

• Significantly Reduce the Capital Costs Required for Downhole Tubulars and Surface Piping

• Minimize Corrosion and Resultant Environmental Concerns with Piping Systems

Unique Competencies

• Multi-layer Extrusion Capability – Bond Polymers That don’t “like” each other

– Achieve Properties At a Minimal Cost

• Braiding/ Reinforcement Technology – “Net Neutral Braid” Technology

– Strength with 10% of the braid

– Aramid Fibers

What makes Polyflow Unique ?

• Nylon and Polyphenylene Liners

• Extremely Lightweight and Flexible Eliminating Conventional Equipment

• Superior Cyclical Loading Performance

• Pull Through Existing Pipelines with Tight Clearances and Bends

Key Considerations for Thermoflex®

Surface Lines

• Liner Compatibility with Fluids • Water only – HDPE • Water with Hydrocarbons, CO2 - Nylon • Water with Hydrocarbons, CO2, H2S - PPS

• Bonded Liners to Minimize Collapse Resistance • Aramid Fibers to Withstand Cyclic Loading • Flow Rate Requirements Can reduce Pipe

Diameter and Costs • Low Cost Rapid Installation and Repair to

Reduce Capital Costs.

Liner Construction & Design

• Multi-layer Design

– Inner Liner • Corrosion Resistance

• Low Permeation

• No Softening /Swelling

– Polymer Selection

• Nylon . . Hydrocarbons, CO2, Brine

• PPS . . . Hydrocarbons, CO2, Brine, H2S

• Keeps Costs Attractive

Inner Barrier

Outer Strength and Abrasion Layer

Reinforcement Layer Considerations

• Multi-layer Design – Cross Braids Provide

Axial Strength

– Longitudinal Braids Provide Tensile Strength to Minimize Stretch

– Aramid Fibers for Fatigue and Strength

• Tubing Strength P=(2*F*n)/D*L

Reinforcement Options

Aramid Steel Glass

Strength High Medium High

Cyclic Loading Excellent Excellent Poor

H20 Environment Excellent Good Poor

CO2/H2S Good Poor Good

Rapid Impact Good Good Poor

UV Protection

• Not Resistant Forever

• Prefer TiO2 package

– White keeps pipe cooler than black

– Long term Data on the additives to the plastic

• Does not help in Fire

Couplings and Terminations

• Required for Each End of the Tubing

• Threaded, Weld, & Flange Styles Available

• Zinc Chromate Plated Carbon or Duplex Stainless Steel

• Joint less Unions

Eliminating Welding

• Pre-fab Risers – Shop Fabricated

– Pre Tested

– Any Configuration

• Couples Right to Thermoflex Tubing

Tools For Coupling

• Portable Coupling Machines (250lbs)

• Up to 4.5”

• For Termination and Union Couplings

• 10,000PSI Hydraulic Pump

Delivery of Tubing

• Comes on Spools

• Length Dependent Upon OD and Pressure Rating

• Spools are disposable – No Deposit, No Return

– Easy to Break Down

Installation Methods

• Direct Bury

• Continuous Plowing

• Trenching

• Pulled Through Existing Steel Pipe – Sizing Dependent Upon

Restrictions in Steel

– Pig with wire line and pull pipe

Modeling Gathering Lines

• Liquid or Gas Modeling

• Comparison to Steel

– Smaller Diameter for Equal Pressure Drop

– Continuous Runs reduces Pressure Drops

• Less Erosion Issues vs. Steel
