George Mitchell: Texas energy baron 1997 discovered hydraulic fracturing ▪ Hydraulic fracturing, or “fracking,” (a drilling process that injects millions of gallons of water, sand and chemicals under high pressure into a well, cracking the rock and to release natural gas and oil. ▪ 45 barrels of water per minute into the well at a pressure of 6,500 lbs/in 2 ▪ 250 ft sections each individually fractured ▪ 2003 horizontal drilling became a widespread drilling process in Texas

Recoverable Natural Gas in Major U.S. Shale Gas Basins is approx. 649.2 trillion cubic feet Marcellus: 262 trillion Haynesville 251 trillion Barnett 44 trillion ▪ Barnett Shale: by end of 2008 had 12,000 wells that were producing 4.8 billion cubic feet per day of natural gas, which is equivalent to 875,000 barrels of oil per day. Resources are so big that companies are calling drilling in shale the “Gas factory.”
