http://nafeez.blogspot.co.uk/2012/12/the-frack-farce.htmlNafeez Ahmed is a writer I have much admired – Bestselling Author, International Security Scholar, Investigative Journalist on the Deep Politics of the “War on Terror” in the context of the Crisis of Civilization – but someone I would not have immediately thought would have expressed my gut instincts about the economics of fracking in the UK; or to put it another way, do the economics of shale gas really add up?
Nafeez takes a look at the unfolding story of doubts about the reliability and durability of US shale gas reserves which have been “inflated” under new Security and Exchange Commission (SEC) rules introduced in 2009. The new rules allow gas companies to claim reserve sizes without any independent third party audit. This is very much the case here in the UK right now. The overestimation of reserve sizes is being used to obscure the dodgey economics of fracking.
The first problem is production rates, which start high, but fall fast. Nafeez cites eminent authorities who have noted that production at wells drops off by as much as 60 to 90 percent within the first year. It is, however, something that any undergraduate geologist would readily understand and expect. This makes long-term profitability difficult, even in the UK context in which the gas markets will not allow any significant drop in gas prices even with greater supply. (I will explain this later). The industry has run into a crisis because it borrowed to finance the set up and production costs on the basis of its fanciful estimates of what it could extract from reserves of essentially uncertain size and accessibility. Prices are therefore rising fast again to save the companies bacon!
Nafeez neatly sums up the lesson we need to learn fast:
Returning to the differences between the US and UK gas markets.
Because of the way the wholesale gas market works in the UK, shale gas production (even at the most optimistic estimates) will have little impact on the price consumers pay.
The upshot of all this is that there these mechanisms are skewed to ensure that UK consumers will see negligible benefits from shale gas, but the producers will have potentially huge profits. The opposite has been the case in the USA. The Shale Gas boom has seen their wholesale gas price plummet, but this has hit profitability of the producers causing many out of production after just 2 or 3 years.
In conclusion – the economics are dodgey ofr the producers; the benefits to the consumer will be negligible; and we all know the environmental consequences will be dire. I strongly suspect that once we get past the speculative phase that tin-pot companies like Coastal Oil & Gas/UK Methane are ankle deep in at the moment, the serious players will realise that the whole escapade simply does not add up – especially on crowded little islands with passionate activists on their case every step of the way. They are not usually that stupid – unlike someone I could name:
