This just in from the Christian Science Monitor. … Another reason why the price of oil is down … AGAIN!
I’ve posted a link a couple of paragraphs to the really long article. The rest of the article criticizes drilling because of possible pollution. There are two parts to the pollution aspect. One is to recover the fracking chemicals that are added to the several million gallons of water used to fracture the shale to release the natural gas (or to minimize their use) to prevent them from getting into local aquifers and water sources.
[They have really accurate “horizontal drilling” … the drill pipe turns 90 degrees and goes horizontal for a mile or so … and then they pump in a few million gallons of water at 10,000 psi to fracture the tight shale. Then they remove the water which brings with it the chemicals as well as salt from underground salt deposits. And all of that stuff in the water has to be removed.]
The other aspect is to include in the land lease to the natural gas driller/ landsman two provisions: water testing before and after AND obligation of the oil and gas folks to protect and provide drinking water supply to the landowner and neighbors. The knowledge base and the technology are there … they just need to be included in the terms and conditions and “addendums”.

Water and chemicals injected at high pressure can extract more gas – and possibly pollute drinking water.

After decades of declining US natural-gas production, an advanced drilling system so powerful it fractures rock with high-pressure fluid is opening up vast shale-gas deposits.
Instead of falling, US gas production is rising, with up to 118 years’ worth of “unconventional” natural gas reserves in 21 huge shale basins, an industry study in July reported. Such reserves could make the nation more energy self-sufficient and provide more of a cleaner “bridge fuel” to help meet carbon-reduction goals urged by environmentalists.
Shale gas reserves have a powerful economic lure. Companies, states, and landowners could all reap a windfall in the tens of billions. Some also predict lower heating costs for residential gas users as production increases.
