Shale gas: 'The dotcom bubble of our times'  

Posted by Big Gav in

The UK Daily Telegraph has a jaundiced look at the shale boom - Shale gas: 'The dotcom bubble of our times'.

Rather oddly, hardly anyone seems to have asked the one question which is surely fundamental: does shale development make economic sense?

My conclusion is that it does not.

That Britain needs new energy sources is surely beyond dispute. Between 2003 and 2013, domestic production of oil and gas slumped by 62pc and 65pc respectively, while coal output decreased by 55pc. Despite sharp increases in the output of renewables, overall energy production has fallen by more than half. A net exporter of energy as recently as 2003, Britain now buys almost half of its energy from abroad, and this gap seems certain to widen. ...

We now have more than enough data to know what has really happened in America. Shale has been hyped ("Saudi America") and investors have poured hundreds of billions of dollars into the shale sector. If you invest this much, you get a lot of wells, even though shale wells cost about twice as much as ordinary ones.

If a huge number of wells come on stream in a short time, you get a lot of initial production. This is exactly what has happened in the US. The key word here, though, is "initial". The big snag with shale wells is that output falls away very quickly indeed after production begins. Compared with “normal” oil and gas wells, where output typically decreases by 7pc-10pc annually, rates of decline for shale wells are dramatically worse. It is by no means unusual for production from each well to fall by 60pc or more in the first 12 months of operations alone.

Faced with such rates of decline, the only way to keep production rates up (and to keep investors on side) is to drill yet more wells. This puts operators on a "drilling treadmill", which should worry local residents just as much as investors. Net cash flow from US shale has been negative year after year, and some of the industry’s biggest names have already walked away.

The seemingly inevitable outcome for the US shale industry is that, once investors wise up, and once the drilling sweet spots have been used, production will slump, probably peaking in 2017-18 and falling precipitously after that. The US is already littered with wells that have been abandoned, often without the site being cleaned up. Meanwhile, recoverable reserves estimates for the Monterey shale – supposedly the biggest shale liquids play in the US – have been revised downwards by 96pc. In Poland, drilling 30-40 wells has so far produced virtually no worthwhile production.

In the future, shale will be recognised as this decade's version of the dotcom bubble. In the shorter term, it's a counsel of despair as an energy supply squeeze draws ever nearer. While policymakers and investors should favour solar, waste conversion and conservation over the chimera of shale riches, opponents would be well advised to promote the economic case against the shale fad.
