The challenge operators face…• Protecting the
well to maximize profitability
• What could harm the well?– Aerobic bacteria– Anaerobic bacteria– Scale species
4
What is Chlorine Dioxide (ClO2)?
• A powerful and selective oxidant.• Extremely effective
environmentally friendly chemical (not just a biocide) against H2S, FeS, polymer damage, bacteria, biofilm and emulsions.
• pH independent…effective at a broad range.
• Environmentally friendly…EPA and FDA approved.
5
What is Chlorine dioxide (ClO2)?
• Effective at levels as low as .1 ppm…. Very measurable and controllable
• Does not break cross-linked gels or harm oil and gas….unless you want it to

On-the-fly treatment• Benefits:
– Reduced chemical costs– Minimal required contact
time– Measurable through
proprietary PCA system– Peace of mind water is
disinfected going down-hole
9
Hydration units are a huge source of bacteria and fouling
Are your tanks really clean???
Traditional Chem-Add treatments really do not clean the blender
PureLine’s ClO2 treats the entire system
10
SWD Treatments• Benefits
– Wellbore integrity maintained
– Lowered pressures– Increased injection
rates– Decrease operational
downtime
11
Poseidon/working tank treatments• Benefits
– Eliminates SRB’s which negatively impact performance of cross-linked gels.
– Treats iron contamination to avoid interference with cross-linked gels.
12
Water flood treatments• Benefits
– Maintain quality of product produced
– Increased production– Wellbore integrity maintained– Maintain or increase injection
rates– Maintain or decrease
pressures– Corrosion of well mechanics
avoided– Decreased production down
time
13
Production well treatments• Benefits
– Increase production– Maintain wellbore
integrity– Avoid corrosion of
well mechanics– Decrease production
down time
14
Pipeline Treatments• Benefits
– Decreased pressures– Increased production
flows– Increased life span
of the pipeline
15
Spearhead treatments• Benefits
– Treat formation with indigenous or man-made H2S
– Prevent sour wells– Achieve higher
production

PureLine Equipment
17
Equipment• Why use PureLine equipment?
– 25 Years Experience– Oilfield ready - small chemical plant - designed to
make ClO2 on demand– Generates 1 lb. – 80 lbs./hour– 95% efficient– All processes have dual components– Few moving parts
• High reliability and low maintenance

How can PureLine help?
• Pre-assessment review.– Gather background information to
formulate risk assessment plan.– Are you doing the right things to
minimize your risks now?• Water supply
– Up-front water quality testing• Disinfected completions equipment
– How clean is your frac equipment?• Healthy Wells/Pipelines
– How do you prevent down-time?• Day to day procedures
– Treatment/maintenance schedule
23
Next steps…• Follow up presentation:
– Greg Simpson: wrote the handbooks on ClO2
– Brian Wrenn: consultant for BP spill• Water sampling and fluid compatibility testing:
– Water quality testing to determine appropriate ClO2 chemistry
– Gel sample testing to confirm ClO2 will not interfere with fluid system
– Procedure designed to treat specific application• Pilot study:
– A trial will be conducted with on site testing– Follow-up testing is conducted to ensure PureLine
achieves desired results.• Finalize equipment needs and chemical deliveries
