On econology we have already talked about this type of gas as especially an ecological and sanitary disaster with contempt of the people !!!

Finally, with 400million years of accumulation of carbon compounds by life underground, we have under this earth, much more of these gases, coal and oil, than it is necessary to burn all the oxygen of our atmosphere, dramatically faster than this oxygen is renewed and suffocate us, if we resist a dramatic warm-up !!!

Yes, but on the other hand, the less we will have to import energy, the happier we will be (trade balance) because it is not tomorrow the day before that alternative energies will cover all our needs.

Apart from emigrating to a country where you must not heat ....

Will be climatic, it's the same ... Or endure, what we could do in a cave at home!

There are not enough caves for everyone, especially in the lowlands! :D

The air conditioning has the advantage, although the techniques are still underdeveloped to be able to be powered by solar energy, according to the needs.

We can store the heat of summer underground for the winter, and it works collectively for sure in Canada and Germany for eternity !!

Alas for the planet, but it is confirmed. Unconventional gas risks seriously competing with renewable energies.
Only positive thing, he will also become a serious competitor for nuclear power.

Energy: natural gas called to play a key role for the planet

Natural gas is promised a bright future. It is the only fossil fuel whose demand will exceed in 2035 that of 2008, and this in all scenarios, estimates the International Energy Agency, in its annual report published yesterday. World gas demand, which fell in 2009 for the first time in 40 years, is expected to pick up this year, with 2% growth. This "golden age" of gas is due in particular to the growth of unconventional gas production in the United States. An area in which Chevron has just made an investment of 4,3 billions of dollars. This rise in power calls into question the competitiveness of nuclear energy and renewable energies.

Quite and with video links, read: https://www.econologie.com/forums/gaz-de-sch ... t9986.html

Not convential it's a bit vague as a definition. Article Factory new talk about unconventional gas and so it's more correct:

What does the term "unconventional gas" cover?

This name refers to three types of gas accumulations. First, there is Tight Gas. These are traditional tanks, sandstone or chalk type, but are very compact and very low permeability. This low permeability makes the gas difficult to extract. It is then necessary to use horizontal wells to increase the contact area through which the gas can enter the well. It may even be necessary to perform hydraulic fractures and inject small, very strong beads that prevent the fracture from closing. Then there is Coal Bed Methane, known as firedamp. This gas is absorbed by the coal. To extract it, the principle consists in digging wells as far as possible in the coal seam, perpendicular to the fractures of the latter, so that the gas joins the well by the fractures.

Finally, the type of unconventional gas that makes the news is shale gas. Instead of being stuck in a tank, the gas is trapped in the source rock where it formed, that is to say in a rock that is not very permeable. It is therefore necessary, here too, to make horizontal wells and fracture the rock.

Shale Gas is everywhere in the world. What is new is the ability to produce it economically. In the United States, research began twenty years ago. It is the technical maturation of know-how, combined with tax incentives, that has allowed this development. A development that no one has anticipated, except for small companies who were the promoters. They have invested in this niche, with a significant impact on national and global production today.


I think that we could very well add behind the "unconventional" the methane hydrates because, even if in the end we get methane, so natural gas, their extraction method is very different and their potential is much greater than that of shale gas ...

We had a topical example on hydrates a few weeks ago (remember in the Gulf of Mexico): https://www.econologie.com/forums/louisiane- ... t9659.html
