  1. GOVERNOR’S SMALL BUSINESS FORUM Apache Corp. JUNE 4, 2014

  2. Drilling Permit Applications – Burleson Co. http://www.texas-drilling.com/burleson-county Note – the size of each dot is about 600 times larger than an actual well site on this map scale.

  3. Barrier Failure or Well Integrity Failure • Single Barrier Failure => No Leak Path? => No Well Integrity Failure • Unless All Barriers Fail, A Leak Will Not Happen • Wells are Designed with Multiple Barriers. • Number of Barriers Depends on the Hazard Level.

  4. Hydraulic Fracturing • What is it? • Hydraulic fracturing involves injection of water. sand, polymer (an adsorbent in diapers and a drinking water purifier) and a small amount (+/- 100 ppm) of a biodegradable biocide into a well to create a fracture in oil and gas bearing rock or to reopen natural fractures that are already there. • Well depths for this operation may vary from 4000 ft to over 10,000 ft. (separation of over ½ mile to nearly two miles) - typical frac height is less than 300 ft (top to bottom) • Water tables in these areas are shallower than 1000 ft. The main biocide we use has been approved for well use in the North Sea – carries the Gold band (safest) rating.

  5. How Close Does the Top of a Frac Come to Ground Water?

  6. Common Frac Chemicals

  7. Mining (coal, oil, gas, minerals) Water Usage? Note: this does not include the effects of water recycling from produced water back to frac water. Water Use in In Perspective: Texas has over half fracture jobs done each year in US – need 80 to 100 billion gallons of water total. City of Houston loses 22 billion gallons per water per yr. in leaks. Texas cities lose 200+ billion gallons per year in leaks. Amount of water in TX to fracs less than 1.6% of total.
