The above chart shows the footprint changes from surface to subsurface over a thirty year period, but the industry writes about the strategic distances (well spacing and more well spacing) from each well head. Any Google Earth drive by shows the insane SURFACE build out of all these fracking horizontal wells. Now there is also a water footprint that is becoming very important to the all of us stakeholders…
The two most common methods of flow back brine treatment is…
1) thermal desalination (boil and evaporate?…uuugh) and
2) membrane desalination techniques (now Dow is in the shale play/recycle water game)
The WaxachachieTX blogspot reported in 2008 of two Railroad Commission approved frac water recycling projects…http://www.waxahachietx.com/news/water-project-ok-d/article_5fe7aa7c-03d8-51bb-a310-eb97059cdae1.html (my notes in boldface)
“The first pilot program, by Fountain Quail Water Management of Jacksboro, was approved in 2005 and has been a technical success (technical success? meaning NOT cost effective?). Fountain Quail, using a mobile heated distillation system (that probably vents the nasties into the open airshed), processed more than 1.6 million barrels of frac fluid to recover 1.3 million barrels of reusable water.”
Here is a video link (click on video labeled “Pioneers in Water Recycling”) where Devon worked with Fountain Quail on frac water recycling. They were not shy in this video to expound on how hard it is to recycle this stuff.
Fast forward almost a decade later 2014, Devon’s “Water Principles” uses the fail language of “where feasible”…..uuh ohh!
- Educating and working closely with governmental authorities, communities, businesses and members of the public concerning water usage needs and the necessity of water management
- Identifying usage needs, determining resource availability and monitoring water use
- Applying conservation practices and identifying opportunities to improve water use efficiency
- Supporting research to develop fresh water minimization practices for our operations
- Employing economically and operationally feasible alternatives to fresh water usage
- Advocating for appropriate regulations on water use and reuse
- Continuing to employ prudent operating practices to ensure the protection of surface and groundwater
- Planning for operations to continue if water availability becomes constrained

So I emailed Devon asking what percentage of fracking waste related fluids is getting recycled, what methods they are using, and what percent of Devon jobs is actually recycling the waste waters….I don’t expect them to answer me back.
