  1. Water and Hydraulic Fracturing 12/18/2013 CATEE Conference San Antonio, TX Dr. Calvin Finch Texas A&M Water Conservation and Technology Center

  2. Water Components • Water for Drilling • Water (Solution) for Fracturing • Outflow (Contaminated)

  3. How Much Water? • 3-7 million/gallons /well • 60,000 acre feet at peak year (TWDB) • 3,800 wells in 2013 • 85,000 more will be drilled

  4. Water Options • Fresh Water • Brackish Water • Treated Water • Propane and ?

  5. Treated Water Major source in Permian Basin fracing because of lack of fresh water available Only 2% on Eagle Ford because of available fresh water • Heat exchange • Lined pit (chlorine shock) • Passive filtration • Ozone bubbling • Configurable filtration train (customized)

  6. Attitudes in Texas Generally sympathetic to need for energy production and desirability of economic activity but not unanimous.

  7. Hugh Fitzsimmons WintergardenWater District Board Member • 25 Artesian wells, now none • Fracing requires more water than we have • Disposal wells are threats

  8. Darrell Brownlow – Landowner and Hydrologist • Agriculture has been mining Carrizo Aquifer water and now Fracing is drawing from an area with much less water available • More short term and long term planning needed

  9. One answer to the concerns and uncertainty. Local and Regional Water Planning

  10. Local Planning • Compare timing of need in fracing, agriculture, municipal uses to reduce conflict • Encourage use of alternate water sources in water sensitive areas, more recycling, transportation of water

  11. Regional Planning • Make sure groundwater districts have access to adequate water modeling services and expertise • Scientific inventory of available water, and analysis of impact that fracing will have. • Seek alternative sources if use of water for fracing is long term threat.

  12. Legislation • Dialogue on what is needed and attempt to present unified front. • Pipelines for flow back or treated water?
