• High IRR plays incentivize drilling activity
• Horizontal drilling activity is the largest driver of waste water production
• Frac volumes and geology determine flowback volumes
• Treatment, recycle, reuse and/or disposal used for wastewater
management, but typically disposal wells are the most cost effective
when viable
• Disposal well viability hinges on geology, water quality, water quantity
and economics

Produced Water Generation in Shale Plays:
Dependent on Geology of Shale Formation
High “Long Term” Produced Water Generating Play
Permian:
− Formation characteristics result in high produced water generation
− Higher volumes of natural formation water present in / near shale
Moderate “Long Term” Produced Water Generating Plays
Eagle Ford Shale
Bakken
− Formation characteristics allow less fluid production per MMCF/bbl
− Relatively dry formation
Low “Long Term” Produced Water Generating Plays
DJ, Utica, Marcellus Shale
Higher water production in South (West Virginia), lower in North (Pennsylvania)
− Shale formation characteristics tend to “trap” fluids
− Very dry formation
− Water is “bound to formation”

Disposal Wells vs Alternative Methods
 Disposal
− Provide producers affordable well-disposal of wastewater
− Water treatment separates solids and hydrocarbons from water prior to
disposal
− Certain facilities are pipeline connected, providing stronger customer
relationship with the producers
 Treatment for Re-Use
− Clean water can be re-used by producers for fracking, well drilling and
completion projects
− Offers producers an alternative to fresh water that minimizes the impact on
aquifers, particularly in arid regions of the U.S.
 Treatment for Discharge
− Cleans water to environmental discharge water quality
 Resource Recovery
− Create high purity brine from oilfield waste water
− Apply crystallization or chlor-alkali process
− Yields valuable chemical products in lieu of waste stream
