What/who is EFD?
Societal perception
Issues/Aspects of Oil & Gas
How can these issues be addressed?
Environmental Stewardship in O&G
-
EFD ProgramA collaborative effort
Industry – Academia ‐ GovernmentEnvironmental Organizations
Providing unbiased science to identify, develop and transfer
critical, cost effectivetechnologies for safe andenvironmentally friendly
developments.

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!
