How Much Fresh Water Are Some Operators Using To Frack A Bakken Well? -- July 20, 2015

Data point from Triangle:

Fractured with:

• 26,532 bbls Slick Rock
• 35,636 bbls #22 Rock Solid
• 1,132 bbls brine
• 8,134 bbls #25 Rock Solid
• 2,903 bbls #23 Rock Solid
• 3,774 bbls SlickRock flush, 
• 67 bbls 15% HCL
• 708 bbls 7.5% HCL
• 677 bbls fresh water
• 115,307 lbs 40/70 white sand,
• 3,652,259 lbs 20/40 ceramic proppant 

USGS data points are linked here:

• Marcellus Shale, Pennsylvania, 4.5 million gallons (Risser, 2012, USGS Public Lecture, "Shale gas, Hydraulic Fracturing, and Induced Earthquakes")
• Wattenburg Sandstone, Colorado, 2.7 million gallons (Goodwin and others, 2012, Oil and Gas Journal)
• Barnett Shale, Texas, 2.8 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
• Eagle Ford Shale, Texas, 4.3 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
• Haynesville Shale, Texas, 5.7 million gallons (Nicot and Scanlon, 2012, Environmental Science and Technology)
• Bakken Formation, North Dakota, 1.5 million gallons (S. Haines, 2012, USGS personal communication)
• Horn River Shale, British Columbia, Canada, 15.8 million gallons (Horn River Basin Producers Group, 2010).

That comparison between Texas and North Dakota is quite interesting, considering the issue of water in Texas, and then the number of active rigs in Texas (400) vs North Dakota (75).
