AWARDS
“EFD is the # 1 Program in the Energy IndustryDeveloping Innovative
Environmental Technology.”‐ Rig Zone
Focuses on field trials, documenting and reporting.
EFD Field Trials Programsince 2012
Societal Aspects associated with Oil & Gas
Where do many get their information?
Images tell stories….but don’t always lead to research.
Eternal Flame Fall, NY
Burning water faucets?!
Burning Springs, NY
What are the ‘real’ concerns?
EFD Societal Team Field Trials
What are some issues respondents reported as concerns with Oil and Gas Development?
Traffic Congestion Water Usage Chemicals
Groundwater Protection Emissions
Flaring Earthquakes
Industry can address these by:Traffic Congestion – temporary pipelines, dust control plans, scheduling
Water Usage – put water use in perspective, treatment, recycling options
Chemicals – FracFocus disclosure, EPA’s Design for Environment products
Groundwater Protection – spill containments systems, proactive measures
Emissions – minimize flaring, waste heat to power equipment
Earthquakes – pre‐lease investigation and lessen disposal by recycling produced/flowback water
Common Chemicals Used in Fracturing Fluids
Most Common Frac Additives
Composition CAS Number Total amt. in avgfrac (10k bbl)
Used in recycled water?
Alternate Use(non O&G)
Friction Reducer Polyacrylamide 9003‐05‐8 100 to 200 gallons. 50k to 70k ppm is upper limit
baby diapers, floc for drink water
Biocide Glutaraldehyde 111‐30‐8 50 to 100 gallons. decrease w/ increasing salinity
Medical disinfectant
Alternate Biocide Ozone, Chlorine dioxide, UV
10028‐15‐6 10049‐04‐4
Turbidity & v. high salinity hindrances
Disinfectant in municipal water
Scale Inhibitor (if needed)
Phosphonate & polymers
6419‐19‐8 & others 10 to 100+ gallons –depends on local
Specific ions like calcium are a problem.
Some cleaners and medical treatment
Gellants(hybrid / gel)
Guar & Cellulose 9000‐30‐0 9004‐62‐0 Depends on frac type ~1000 to 2000 lb.
Ca++ , Fex & TDS problem
Thickening ice cream / soup
Acid 5% TO 15% hydrochloric
7647‐01‐0 ~0 to 2000 gals not universally
Yes food prep, swimming pools
Acid Corrosion inhibitors
Quat. Ammonium salts, Coa CoaAmines, etc.
Various 2 to 40 gals if acid is used
Yes Industrial
Other measures industry can take to address issues…
Industry has come a long way….and can do more. Make Environmental Stewardship a HABIT!
