Why Recycle
Lower Ranch, County, State, Fed Hwy traffic
Use of less Potable Water
Lower costs for Oil & Gas Operators
Less injection well volume

Facts to Consider
Water vol/well: approx 6 million gals (O&GJ July’12 PDittrick quote Pres of Breitling O&G)
Number of Wells in Eagle Ford Shale:
- 3500 permitted in 2013 to date (EFS.com)
- 11,000 wells permitted since ’08 (Fuelfix Sept 19,’13 JHiller)
- 85,000 more will be drilled in EFS (per Drillinginfo CEO in Fuelfix 9/19/13 article)
Truck traffic: 500-1500 trips per well; TxDot reports 1184 truck trips/well
(EFS Task Force RRC Study Chap 2, p24 Study)
Water truck traffic variables:
volume of well, piping, recycling, reuse, logistics, storage, SWD injection
SWD’s: Injection well volume (EWS results show 80-95% reductions)
Aquifer: water usage reduced with “life of field” Recycling
