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
