Through the Lens: Fracking
Posted October 31, 2011
What does hydraulic fracturing look like? The slideshow embedded below takes an up-close look at fracking - the breakthrough technologies and procedures used to produce natural gas from shale rock formations thousands of feet below the surface.
My favorite photo: A detail shot of sand grains in a worker's palm. Fracking fluid is 90 percent water, 9.5 percent sand and 0.5 percent chemicals. Once the rock is fractured, sand in the mixture keeps the cracks open so natural gas can escape and be collected. The term "hydraulic fracturing" sounds pretty traumatic, but cracks in the rock are no bigger than the grains of sand.
