One of the things I have heard the most frequently since I began researching fracking brine is, that it is safe as long as the well casings do not fail. So, how often do well casings fail? Question and answer session and video below...
Q: How many well casings fail right off the bat, leading to methane migration?
A: 6.2%
Q: How many well casings fail over a 20 year time span?
A: 60%
Q: Do any well casings last forever?
A: They ALL fail over time.
Q: Where do these figures come from?
A: The Pennsylvania DEP
Q: Why doesn't the oil & gas industry fix these problems and make well casings that actually work?
A: They can't. There is no way to guarantee safety. Natural things like drilling through earth and stone cannot be controlled or predicted.
Q: Where can I learn more about this?
A: You can watch a Cornell University engineering professor, Dr. Ingraffea, explain if you would like. The video is embedded below.

ReplyDeleteThis You Tube video about the hydrofracture drilling process and why there is no way safety can be ensured is very informative and well worth the time it takes to watch it.
