Get Fracking! 5W1H Method

Get Fracking!
Invented it
Has made a killing from it
Will lose out
Petroleum engineers have been fracking for over a hundred years. They've known for ages that fissures in source rocks improve the flow of oil into reservoirs and so increase recoverable reserves. So already in the 1860s engineers were packing nitroglicerine underground and detonating it. But it was the first oil shock that made the US government and oil industry seriously interested. Research in the 1980s produced the hydraulic fracking of today, with Texan gas company Mitchell Energy being the first to come up with economically viable "slickwater fracking".
The oil and gas companies from the Southern USA (especially Texas, Florida and Oklahoma) who pioneered the technique (like Mitchell Energy) and bought up drilling rights in areas previously considered of no value.
Landowners on the big gas bearing shale formations in the USA - the Marcellus Shale, mostly in Pennsylvania, and the Barnett Shale, further south
The oil majors who got into the game late and overpaid for US acquisitions
Companies with competing, but more costly, energy assets, like deepwater offshore oil and gas and coal mines
Russia, whose Gazprom has contributed massively to state wealth, if and when the shale revolution hits Europe. Same will go for Algeria, that has profited handsomely from supplying mainland Europe in gas. Countries with big conventional gas reserves a long way away will also feel a new pinch. Western Australia, Central Asia, Iran and Qatar will all be hit.
Are the reserves
All over the world, including places like China and Western Europe that have traditionally thought of themselves as being energy poor
The UK has two major shale formations - one in the North West, in Lancashire and under the Irish Sea - the other in the South, stretching from the South Downs to Dorset and Somerset. Production in the economically depressed North West is greeted with more enthusiasm than in the rolling countryside of the booming and over-crowded South of the country.
Will it come onstream in the UK?
2015, according the Chancellor's autumn statement this year.
Will energy bills fall?
Household bills in the UK may not fall that much - certainly they are unlikely to fall as have done wholesale prices in the US. The government will set royalty rates at the level the market will bear, and that'll be close to current levels. (In the US, the owner of the land owns the resources underground. No single owner has the monopoly power to set prices, so they tend to be lower.) There is also a battle raging at the heart of government between the Treasury and the Department of Energy and Climate Change (DECC). DECC wants 80% reductions in greenhouse gas emissions by 2050, so wants energy prices kept high. The Treasury is more interested in government finances and growth. But whoever wins, continuing high gas prices are likely to be the result. There might be some pass-through of benefits to large industrial users, but don't expect household bills to fall.
Do you engineer it safely?
Everyone agrees that fracking needs careful engineering. Methane leaks need to be stopped by building sound concrete casing around the bore-holes. This will also stop groundwater contamination. The quantity of nasty chemicals used to keep the fractures open (acids, emulsifiers) could be reduced significantly. Some engineers have even suggested that air could be used instead of water to fracture the shale.
Will it contribute to ending the economic crisis?
Cheap domestic energy will create an investment boom that could kick-start the economy. The existence of cheap high-quality energy will make heavy industry and manufacturing investment more attractive which will have the much-vaunted longer term effect of rebalancing the UK's economy away from financial services. Already in the US there is a move to "on-shore" production of steel and chemicals because of the availability of cheap energy.
Are governments so keen?
doesn't Greenpeace like it?
do some more moderate greens like it?
In the UK, the Treasury could make a killing from Shale gas. All underground resources are owned by the state which has proved adept in the North Sea, for example, at setting royalties - the money paid by the operator to the government - just at the point at which it just makes sense for oil companies to keep exploring and producing. The government will do just the same with onshore shale operations. The North Sea oil bonanza allowed the Conservative government of the 1980s to keep taxes low, to beat the coal mining unions and to balance the books. What statesman wouldn't want a repeat of that?
Greens used to get some comfort from the idea that "peak oil" was upon us. Fossil fuels would run out, so even if the mainstream wasn't going to take renewables seriously for good environmental reasons, the coming shortage would make everyone pay attention. But shale gas changes all that. We won't be forced into really green energy - solar, wind, geo-thermal - any more.
There's not much hope of seriously denting our greenhouse gas emissions until a cheap clean alternative fuel is found argue some moderate, realist greens. Shale gas is better than oil and coal for making electricity and it gives us the 30 year window to develop the technologies we need - better solar, wind, nuclear (maybe even fusion) and efficient bio-fuels.
Is it?
Are the big pro's?
and con's?
There are environmental worries
it makes earthqukes
It produces CO2 when you burn it
It might leak methane when you drill for it
It uses huge amounts of chemically spiked water
It can mix methane gas and other nasty substances like lead and zinc that run-off from the shale into drinking and irrigation water
Caudrilla, the UK company that's been exploring Lancashire's Bowland Shale, was stopped from any more fracking in 2011 when it caused 2 tremors measuring 2.6 on the Richter scale. There's no doubt the fracking caused the tremors, though there is great doubt that such small tremors can cause any damage.
Natural gas (methane) is cleaner than coal - it produces 4 times less carbon dioxide for each unit of energy than coal or oil - but it is still far from being a green, renewable energy source.
Methane is a much more potent greenhouse gas than carbon dioxide. So although gas is cleaner to burn than coal, that might all be for nought if there are leaks from the wells.
Lots more cheap energy
200 years' worth worldwide, according to the International Energy Agency. Gas prices in the US - where the industry is most advanced - have fallen from 8p/therm to 2p/therm. It's no longer economical in the US to burn coal in power stations.
Basic Geology
Basic Engineering
You drill a hole some 6000ft down then drill several holes horizontally across. You inject water under high pressure to fracture the shale, and, once that has drained away, inject sand, acid and other chemicals down to maintain the opening of the fractures. It is through these crack that the gas will collect. A separate well is drilled and lined to bring the gas to the surface where it connects up to a pipeline.
Over hundreds of millions of years, living matter has been deposited at the bottom of lakes, riverbeds, swamps and seas. The material has been trapped and weighed down by the pressure of more millions of years of sediment. In that pressure cooker, the trees, plants, shells, seaweeds etc turn into oil, coal and gas. The oil industry has known for over a century how to find wells and seams where this valuable stuff has concentrated. But there's lots of it that is much more diffusely stored in the old sediment. Shale - mostly layers of clay and slate - can trap a whole lot of it in gas form a bit like a sponge traps water. What has been discovered in the last 20 years is how to wring that sponge. The technique in use today is called "slickwater fracking" in which soapy water is injected at high pressure into the shale rock to create veins that the gas can flow through and eventually be expelled out through a drill hole.
