The cornucopian’s believe the so-called revolution in the shale oil and gas markets will be the saviour to our ever declining conventional oil resources globally, the one that supports and underpins our on-going economic ability to continue business as usual.
If you take the US as an example of the false euphoria, look at the reality:
Since peak oil production in 1970, the number of operating oil wells in the U.S. has stayed roughly the same while the average productivity per well has declined by 42 percent.
Since 1990, the number of operating gas wells in the U.S. has increased by 90 percent while the average productivity per well has declined by 38 percent.
Shale plays suffer from the law of diminishing returns. Wells experience severe rates of depletion, belying industry claims that wells will be in operation for 30-40 years. For example, the average depletion rate of wells in the Bakken Formation (the largest shale oil play in the US) is 69% in the first year and 94% over the first five years.
The very high decline rates of shale gas wells require continuous inputs of capital—estimated at $42 billion per year to drill more than 7,000 wells—in order to maintain production. In comparison, the value of shale gas produced in 2012 was just $32 billion.
The recent announcement of one of Australia's biggest energy find reminds me of the spin verses reality that usually follows these so-called revolutionary discoveries in the energy field.
So despite all of the rhetoric in the article, one of the key drivers of a societies wellbeing has been ignored, interesting!
