  1. The Use of Reinforced Thermoplastic Piping Systems for Water Transport and Disposal of Fluids in The Marcellus Shale PIOGA Spring Technical & Environmental Seminar April 7-8, 2010

  2. Critical Issues with Brine in the Marcellus Shale • High Salinity is Very Corrosive (200K PPM) • Hills Require Significant Pressure or Increased Pumping Stations • Landowners Want to Minimize Property Impact • How can Installation Time and Costs be Reduced

  3. What Are Composite Pipes? • Multi-Layer Construction • Inner Barrier Layer • Middle Reinforcement Layer • Outer Abrasion Layer • Continuous Spools

  4. 11000 12000 10000 H2 7000 8000 6000 4000 2000 800 300 20 0 Critical Issues for Inner Barrier Layer • Water/Brine . . . HDPE, PP, Nylon, PPS No Degradation • HDPE, PP Soften in Hydrocarbons • Permeation Issues with Olefins HDPE PP PET PPS Vectra cm³/m² d bar]

  5. Reinforcement Layer • Types . . . Steel, Glass, Aramid, Carbon • Reinforcement Compatible with Environment • Weight Considerations • Cyclical Fatigue Issues with Injection and Water Pumping

  6. Reinforcement Layers

  7. Elevation Change In PA • 1,200ft Elevation Change (520PSI) • Pressure Drops Up to 50% Less with Composites • Low Pressure Centrifugal Pumps vs. Positive Displacement

  8. Facts on Pumps Centrifugal Pumps • 300-350 PSI Max Range • 65% Efficiency (Higher HP) • Multiple Pumps for 1,000ft hills Reciprocating Pumps • 0-750PSI Most Cost Effective • 95% Efficiency • On Pump for 1,000ft Hills

  9. Reduce Environmental Impact • 20ft Right of Way vs. 50ft for Steel • Pull Pipe Out then Trench • Dragging Pipe Does not Impact Pipe

  10. Installation Advantages vs. Steel • Installation More Rapid Than Steel • Light Weight Product Reduces Equipment Requirements for Installation • Terminations and Risers Eliminates Welders in the Field and Saves Time • Savings $5-8/ft vs. Steel

  11. Installation Techniques • Pull Long Lengths off Spools • Single or Multiple Lines • Keep Spools in One Location

  12. Installing with Steel • Can Be Placed Next to Steel • Slows Down Composite Pipe Installation • Right of Way Larger with Steel

  13. Backfilling • No Sand Bedding Required • No Need for Clean Fill • No Special Tamping or Compaction

  14. Boring • Same Process as Steel • Direct Pull Through or Through Conduit • Lightweight allows for Multi-mile Pulls

  15. Terminations • Flanged, Weld Style Threaded, • Spliced Coupling for Unions • Portable Coupling Machine (250lbs) • Carbon Steel/ Fortron Coated or Duplex Stainless

  16. Prefabricated Risers • Eliminates Field Welding • Any Configuration Available • Coated ID for Corossion Resistance

  17. Why are Composite Pipes for Marcellus Shale Operators? • Corrosion Resistance for High Salinity Environment • Minimal Right of Way Impact to Landowners • Low Pressure Drops versus Steel Allows for Increased Flow Volumes without Excess Pressure Drop • Minimal Equipment for Installation Reduces Costs • Rapid Installations Creates Faster Tie-ins and Reduces Costs • Reduces Operators Investment in Water Movement
