• Johann Ritter discovered "UltraViolet" light
• Marshall Ward discovered UV light kills bacteria
• UV used for drinking water treatment
• UV treatment for wastewater
• New water standards required by EPA
(conventional treatment insufficient)

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

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

UV Light Disinfection
• Fast-acting
• Broad spectrum of activity
• Non-chemical treatment
© 2013 HALLIBURTON. ALL RIGHTS RESERVED.
• Dependent on fluid turbidity
and transmittance
• No residual kill
9
Solutions to Limitations
 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

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