$this->bbcode_second_pass_quote('Tanada', 'F')racked shale may be as abundant as shown on that map, but if they are all going to follow the steep decline rates seen so far in the USA how long will it take until this bubble runs out?
Yup. Thats what I'd like to know as well. How much oil from tight shales? How long will it last?
$this->bbcode_second_pass_quote('Tanada', 'I')n the mean time fracked shale oil is keeping the oil price relatively stable, what happens if tight oil can not replace conventional decline? That's right, peak oil.
Exactly. So far tight oil has helped postpone peak oil by ca. 9 years. Thats OK with me....I'm in no hurry for the global economy to collapse. AND if KSA and/or Russia and/or Alaska and/or Australia and/or EU and/or Africa and/or South America all start producing oil by fracking shales, how much longer will peak oil be postponed? Have we got another 10 years of stable or even slowly rising global oil production to look forward to?
Where are we headed? In order to answer that question
you've at least got to ask how much longer can fracked oil from tight shale postpone peak oil? 
How much longer?

$this->bbcode_second_pass_quote('Plantagenet', '')$this->bbcode_second_pass_quote('JV153', 'T')he sweet spots are ok, but once it goes beyond that it's over.
Absolutely right.
So where are the sweet spots for frakking in other countries? You have to understand that first, and then get a grip on the timing of development of those shales, before you can say when it will be over.

You seem to have forgotten something. The above statement is a best case scenario.
1) Fracing requires lots of water, drilling equipment and all the related ancillary equipment and chemicals. The US fraced more LTO wells last year then the entire rest of the world combined. The US has all that equipment and oil production because that oil industry
grew up in a favourable environment with high EROEI's and plenty of other raw materials, which only just now is becoming less favorable (that's why they're fracing

).
2) Fracing would increase oil consumption dramatically in every country where it would be done, which would require increased imports of oil - from ? (Russia (?) which is having economic sanctions imposed upon it

)
3) Europe has heavy environmental restrictions that would prevent it
even if it had the equipment and the fuel do it. These restrictions would have to go.
4. African countries don't have the heavy industry needed for oil drilling - the equipment would have to be brought in from the US. African countries also aren't exactly known for being flush with cash.
5. China - China seems to enjoy a favourable relationship with the US and has cash reserves to buy US drilling equipment and expertise. Environmental restrictions are lax in China. I could see fracing happening in China, otherwise I don't see it happening. Saudi Arabia also has a good relationship with the US and plenty of cash.
So.. widescale fracing will happen when US oil companies are permitted to come in and start extensive fracing operations, bringing in the necessary equipment, and
the necessary fuel requirements are met. In return, since fracing will produce so much cheap oil, the US will get a nice share of the produced oil along with significant quantities to be used in Europe, Africa and South America (or else what's the point). Sounds almost plausible

I take your point, but you also seem to have forgotten something. You are the one who posted the rosy scenario about utilization of "sweet spots" quoted above, not me. I just asked you to elaborate on your scenario quoted above.
ANYWAY, here's my opinion: its hard to know whats going to happen with future global oil production levels given the high level of uncertainty about the future magnitude of oil production obtainable by frakking tight shales, particularly in areas outside the US. I'm surprised more people don't acknowledge this now, especially since no one in the peak oil movement foresaw the importance of frakking, and yet here we are 9 years past the 2005 date that was supposed to mark the peak of global oil production, and its still slowly increasing. Why is that? A big reason is the success of frakking in the US. And yet people don't think this technology will be applied elsewhere in the world? Really?
Its easy for you to make a list of things that might inhibit the widespread use of frakking to produce oil from tight shales outside the US. Peter S. posted a similar list earlier in this thread. Buts its also easy to generate a list of reasons why countries overseas will almost certainly follow the US in using this technology to produce oil, i.e.
1. countries that adopt frakking might be able to get rich by taxing oil production
2. countries that adopt frakking can produce good-paying jobs for their people
3. countries that adopt frakking can develop oil industry related economic activity in their countries
4. countries that adopt frakking can improve their strategic position vis-a-vis their neighbors
5. countries that adopt frakking can gain energy security
6. and there are hundreds of other knock-on positive effects from growing wealthy etc. etc.
I think widespread frakking of tight shales will almost certainly spread around the world, starting with those shales that are geologic "sweet spots." The Vaca Muerto tight shale in Argentina, discussed above, is an example of this new overseas use of frakking. This will help cushion the reduction of oil production from conventional oil fields. AND I think Gail and other peakers are making a mistake not to consider this factor.
