4.Flowback and Produced Water

5.Wastewater Treatment and Waste Disposal

Water Acquisition

Water Acquisition• Intake to meet impingement mortality

and entrainment standards

Same Line (Permanent)

Water Trucks – 100 barrelsYellow Frac Tank – 500 barrels

Conveyance: No One Likes Water Trucks…

Baseline Data and Permits• Baseline Surface Water, Groundwater, Air, Topography• Construction Permits (pads, roads, impoundments, gas

treatment/compressor stations)…any disturbance!−Notification −Cultural Resources−T&E Species (plants and animals [bats, rattlesnakes…])−All about E&S Controls (Erosion and Sediment Controls)−Set Backs (from schools, drinking water, etc.)

• Freshwater Extraction: Pass-bys based on Q7,10 flows• Hauling Permits and Permitted Routes• Wastewater Treatment (Flowback and Produced Water)

NORM TENORM – Technically Enhanced NORM

New Developments/Old Concerns• In 2014: Next EPA Study Potential Impacts of Hydraulic

Fracturing on Drinking Water Resources

• Use Less Water and/or Natural Gas Liquids or Nitrogen Foam – Decrease Dependence on Water…Less Wastewater.

• Decrease Additives or Use More Environmentally Friendly Additives.

• Seismic Events? Mostly due to wastewater injection (OH)

• No More Photos of Ignited Kitchen Faucets PLEASE!

• Mechanical Integrity Tests on annulus

Stray Gas?No Bubbles…No Troubles

“Fracking…Hydraulic Fracturing (HF)

• > 60 years: more than 1 million wells in 27 states

• 90 percent of oil and gas wells use HF technology

• 99.5 percent water/sand mix

• 3 to 5 million gallons of water fractures the shale.

• Well casing protects water supply

• PA Chapter 78 upgrades reflect best practices in well casing

42 | MARCELLUS SHALE COALITION

Vertical Setbacks – from Frac Zone

• At least 1,000 feet from top of Frac Zone to Freshwater Aquifer (blue stripe at top)

• At least 2,000 feet from top of Frac Zone to Ground Surface

Access Road w/ Erosion and Sediment Control Structures

Rock Construction Entrance to Public Roadway

Erosion and Sediment Control Measures Under Construction (RCE)

Well Pads – E&SC Considerations

• Keep clean water offsite. Control water onsite and filter and re-infiltrate onsite or filter before it goes offsite. Reduce TSS!

• Sediment traps may be better choice than sediment basins

• No compost filter socks or silt fence unless very flat

• Clean water diversion swale up gradient to level spreaders

• Riprap-lined channels around pad to sediment traps

• Infiltration basins used when soil types are conducive

• Stormwater Management - due to the increase in impervious area

Access Roads – Design Considerations/E&S

• Assume Road Width for Two-way Traffic

• Rock Construction Entrance (RCE) ±130’ Wide at Public Road

• Radius of the Tapered Curve of RCE ±50’

• 50-foot Radius into Well Pad and Tank Pad

• Coming off the state/local road with the access road - assume 10' @ -4% from EOP (driveway pipe/culvert will be placed at this point).

• 10% max grade preferred

• Roadside ditches (lined with riprap) placed on the upslope side of the access roads

• Road is in-sloped at 2%

Freshwater Procurement

• Basin Approach to Water Management

• Water Consumed and Not Returned to the Basin

• Water Used and Returned to the Basin

• Do Not Move Water Between Basins…Invasive Species

• Extraction Limits per Day

• And, “Pass-by” when source is low, can’t take any water

Flowback and Produced Water StorageTanks or Impoundments?

• High Risk Fluids

• Compatibility Issues (TDS)

• Bolted Stainless Steel Tank Capacity – 45,000 barrels

• Impoundment Capacity – 300,000 barrels

• Temporary Impoundment – 100,000 barrels

Watch for:• Incompatibility with Liners• Scaling and Precipitation Potential

Don’t want any leaks

Thank you!

The Marcellus Shale recently surpassed the 12 BCF per day mark as outlined in various press reports based on the latest Energy Information Administration data. If the Marcellus Shale region were a country, it would be the eighth largest natural gas producer in the world. In other words, the Appalachian Basin is the region for business development, investment, and advocacy – with MSC membership at the heart of it all.
