Hydraulic Fracturing a.k.a. Fracking, is a very poorly understood and yet, much-feared process. It strikes dread into many hearts but most people don't even know what it is. The process of fracking begins by drilling a well vertically to the depth of the oil and gas reserves which are usually found 1 - 2 miles (1.6 – 3.2 km) below the surface. Once the vertical column has been opened, the drill is turned 90 degrees and drilling continues in the horizontal direction for thousands of feet. Once … [Read more...] about What is Fracking and how does it work?
