  1. CleanStream® Service Capabilities

  2. Ultraviolet CleanStream®Service • Mobile bacteria control which uses ultraviolet light technology • Minimize or eliminate need for biocides DNA After Exposure DNA Before Exposure

  3. History of Ultraviolet Disinfection

  4. CleanStream®Service – Benefits • Control bacteria growth in fracturing fluids • Reduce or eliminate volume of chemical biocide required • Provides inherent HSE advantage by reducing transport and handling of chemicals

  5. Blender Frac Tanks CleanStream®Trailer – Rig-Up • Blender suction pump pulls fluid through the CleanStream unit • 8 bpm per suction hose • 100 bpm max rate

  6. 2nd Generation CleanStream®Trailer – Rig-Up • Blender suction pump pulls fluid through the CleanStream unit • 8 bpm per 4” suction hose • 118 bpm max rate • Manifolding enables rig-up parallel to blender or frac tanks • Addition of ACE controls

  7. UV Light Chamber

  8. UV Lamps • Mercury-vapor electric lamps • Commercially available • Medium pressure • 5.8 psi to 580 psi • Output 240 – 280 nm wavelength • Housed within quartz sleeve • 90% or greater UV transmittance

  9. UV Light Disinfection Cons Pros • Fast-acting • Broad spectrum of activity • Non-chemical treatment • Dependent on fluid turbidity and transmittance • No residual kill

  10. Effectiveness dependent on UV transmittance Test prior to job Test during each stage of well Bring biocide as back-up Adjust blend with fresh water No residual kill Run reduced biocide concentration i.e. 0.1 – 0.2 gpt BE-9 Solutions to Limitations

  11. On-the-job Testing Transmittance test Serial dilution test ATP test Lab Testing • Pre-job Testing • Transmittance test • Serial dilution test

  12. Measurement of the amount of light that penetrates through water Tested with spectrophotometer in pre-job and on location testing Transmittance Figure Provided by Aquionics

  13. CleanStream®Unit Operating Range

  14. Aerobic phenol red vials Anaerobic sulfate-reducing bacteria (SRB) vials Incubated for 72 hours Yellowcolor change when aerobic bacteria present Black iron sulfide precipitate when sulfate-reducing bacteria present Serial Dilution Testing

  15. Serial Dilution Test Example 100% Reduction in Aerobic and SRB Bacteria
