Frack Me!

[KeithD]

......the gas leaks out into the other units, particularly drinking water aquifers, as it comes back up the well. Lots of outrage has been directed towards the fracking itself, but the worse culprit is a bad cement job (Faulty Wells, Not Fracking). Almost all of the TV spots, heart-breaking stories of homeowners, and burning faucets are actually from bad cement jobs, not the fracking."

You do know not one bit of evidence exists about this? Aquifiers are only in the top 10% of the drill hole. However plenty of evidence proves that none of these stories are a result of fracking. The burning faucet story was found to be natural methane in the aquifer. The people putting these stories about are just using passed on information with no solid basis of proof.

What I do know is that to fracture shale a lot of pressure is required. That pressure is sufficient to exploit a weak cement job and find its way to surface (or into aquifers). There have been a number of well documented examples of pressure in a well getting to surface from deep down, including the Maconda well and the Ocean Odyssey disaster some years back where weak cement jobs have been partly to blame. The Maconda well was a lot deeper than any of these proposed frack jobs in the UK.

If Fracking is handled well it can and will work but safe procedures are required to ensure that.

Another area for concern is the local geology in any region. Faulting will also provide potential conduits to surface.

Its actually great for me as Fracking will provide more work in the hydrocarbon industry but that doesn't stop me from forseeing fun and games for some folk in the future.

I am glad I am not living on top of the Bowland Shale formation.

3 areas for potential failure:

Poor cement jobs.

Faulted geology.

Poor procedures.
