With all the recent hype about hydraulic fracturing or “fracking” for natural gas, and concerns about possibilities of underground drinking water contamination, it may be easy to lose sight of the real physical work that takes place and the technology involved.

This video is the first of a two-part Chesapeake Energy video series that uses graphics to portray exactly what is done in drilling and pumping water into an underground shale.

This video focuses on the technology that drills a well and then coats it with cement as a sealant. In the video, the company stresses the benefits of horizontal, rather than vertical, well drilling.
