A Benefit Of Fracking

To many there isn’t one benefit from using fracking to extract gas from the ground.  but here’s one even the most total opponent of the technique might concede.

Modern Railways this month states the following.

The major rail operators in the US are all reporting reduced profits as coal volumes plummeted by up to 20% in the last year. Here, the shift in generation mix is being driven principally by the exploitation of shale gas now being produced on a massive scale as a by-product of crude oil exploitation. although a frighteningly high proportion of this gas is just flared, sufficient is being used in power-generation to undermine the need for coal, and for rail freight.

I would suspect the facts are correct. So fracking is cutting the need to burn coal, thus reducing global warming, as burning gas creates less CO2.

  1. Fracking is an existing system of extracting more oil from Oil Wells {by opening up the extraction zone deep underground} . . . Fracking becomes an Issue with Shallow Coal Seam Gas Wells {200 to 1000m} where Coal is already heavily fractured [with gas retained under pressure by water within the fractures] . . . when this pressure is released, gas follows easy pathways. In Oz, some rivers now have gas bubbling to the surface, some land areas are also releasing gas [tested by lighting discharge & now flaming . . . and some capped wells leak gas . . . Fracking ? make up your own mind.

  2. I went to a lecture at the London Geographical Society about fracking and the guy said that it’s all down to the geology. So in some places it will be safe and in others not. But we need more research. I think most of the fracking in the States is much deeper than the figure you quote.

  3. I cited Oz Fracking . . . which also leads to making sure that drilling design protects underground water : Drill a Steel Lined Outer for depth plus of water table with steel lined inner [fill in between with special concrete filler : then drill Coal Seam Well inside the inner . . . so the Coal Seam Gas cannot get into water table. The fracking problem occurs at bottom of well [directional drilling out horizontal some distance] . . . can open up fractures that eventually seep out to the surface [bypassing in some worst cases] & occasional gas releases. USA is recovery Shale Oil Gas [much deeper].

  4. For UK Coal Mines close to the ground [like the Sydney Metropolitan Area] care must be taken . . . Sydney Councils have now stopped Coal Seam Gas [Shallow, Easy to Drill wells & about 90% plus Success Rate] . . . Except some Test Wells & Pilot Wells were drilled in Local Parks among Urban Housing [imagine the ordours of sour gas & swamp gas . . . next door]. Then with Facking the risk of Gas comming thru unexpected pathways to surface . . . this could happen in UK, where townships grew up around Coal Mines . . . be careful . . .

    • Most of our fracking s being tested in non-coal mining areas in shale.
