How Hydraulic Fracturing (Fracking) Works Video

Here’s a quite good six-minute video on fracking put out by Marathon Oil. It’s a very good intro to how the vertical wells are drilled, an explanation of how the lateral drill through the shale formation is done, followed by the fracking process itself in which water is injected into the well itself to open fissures in the shale which allow the oil to flow. It’s well animated, and there’s a lot of information packed into six minutes.
