Energy From Shale is yet another generic new front group created by America’s Natural Gas Alliance (ANGA) to advertise the illusion that the highly polluting process of shale gas production is really shiny, clean and green. They recently launched their first PR effort, asking us to “Think About It.” Believe me, ANGA, I have.
Even when done correctly, fracking cannot be done safely.
All cement wellbore seals, every last one of them, will fail over time. Cement simply doesn’t last forever. Steel can crack. Even if drillers get everything exactly right the first time, cement will become porous due to heat and pressure. Earthquakes, whether caused by nature or deep waste injection wells, hold the potential to damage seals. In about 50-60 years tops, according to gas industry estimates, most wellbore seals will fail, eventually enabling pathways for fluids and gases to communicate with aquifers, geological formations or the environment.

The good news is, drillers have the technology to reseal and replug failed wellbores. The bad news is, they have to do it fairly often. More than 5% of wellbore seals fail immediately. (more…)
