The truth about fracing. (If you have a problem with the industry spelling using a hard "c", you can take your antics up in public with the Celtics). Adding a "k "is a nice propaganda tool to infer.... well you know, the thing. All rock is naturally fractured. At subterranean depths those fractures are compressed. Rock also has characteristics of permeability and porosity; Hydraulic fracturing is simply the use of hydraulic pressure from a column of fluid to open up those fractures and "prop" them open with sand or other proppants like ceramic beads. The chemicals used in frac water solutions are the same as those used to kill bacteria in city drinking water. Guar gum and xanthum gum used in foods are used as thickeners to keep the proppant uniform in the solution so that it actually goes into the fractures that are opened.
