  • 3. Shale Gas Controversy: WaterSource : various sources, retrieved from web February 2013
  • 4. Reliable information, data ?Source : various sources, retrieved from web February 2013
  • 5. Shale Gas – why water ?Shale gas: non–conventional gas : tightlow permeability→Idea: increase permeability shaleSolution : Frac shaleWater function– Lubricate: drilling mud– Deliver chemicals to keep well clean andincrease permeability– Pressure to fracture rock and enable gasto flow into the well– Carry sand (propant) to keep cracks open
  • 6. Industry challengedShale Gas Industry:– Natural Gas Price downward trend US– Operators must reduce costs, risks impacton environment and reputation– Water has become major concern– → Treat and re-use water : priorityWater Treatment Industry:– Caveat : every well is different !– Flowback, Produced water treatment andbeneficial re-use– Reduction costs and risks

Researchmay show much more water needed forspecific shale play.Total fresh water withdrawals in Nord-Pas-De-Calais in 2010: 533 Mm³ (1)Therefore shale gas exploitation couldhypothetically require ~ 6% of totalfresh water withdrawal in 2010.Agriculture water use Artois Picardie in2010 : 35 Mm³2003 2004 2005 2006 2007 2008 2009 20100100200300400500600700Agriculture Drinking Industry OtherWaterWithdrawalUsages(Mm³)Water Withdrawal Water Agency Artois PicardieBreakdown by Usage, 2003-2010
  • 12. Quantity : Produced WaterProduced water: (def. gas and oilindustry): water flowing to surfacethrough borehole.– Flowback frac fluid: 20%-70%– Formation water:• Varies according to shale rock• e.g. Marcellus shale, rock, drier thanBarnettLarge water volumes to manage– → Protect natural environment– → Cut natural water withdrawals, returnclean water to nature.
