When people talk about Peak oil or peak anything, they only look at current prices and the available quantity of declared reserves, which they see as fixed and which they equate with neo-Malthusian insights of shortages.
They do this without comprehending the economic value of resources and without understanding the concept of human action—or that people don’t just standstill in the face problems, we react by working to resolve such unease via the price mechanism.
People, via the markets, respond to prices. This means when scarcities are projected via price signals, the market resorts to either conservation (rationing) or substitution.
This brings us to the announcement by the US EIA that shale gas production is a global phenomenon, with US having been the pioneer in its development.
The EIA writes, (bold highlights mine)
The use of horizontal drilling in conjunction with hydraulic fracturing has greatly expanded the ability of producers to profitably produce natural gas from low permeability geologic formations, particularly shale formations. Application of fracturing techniques to stimulate oil and gas production began to grow rapidly in the 1950s, although experimentation dates back to the 19th century...
The development of shale gas plays has become a “game changer” for the U.S. natural gas market. The proliferation of activity into new shale plays has increased shale gas production in the United States from 0.39 trillion cubic feet in 2000 to 4.87 trillion cubic feet in 2010, or 23 percent of U.S. dry gas production. Shale gas reserves have increased to about 60.6 trillion cubic feet by year-end 2009, when they comprised about 21 percent of overall U.S. natural gas reserves, now at the highest level since 1971
Shale gas production from the US has been exploding. (From the EIA) This accelerated progress has been buttressed by (free market induced) technological enhancements.
Shale reserves have likewise been expanding along with production. This proves the case of the growing economic value of Shale gas.
Shale Gas reveals of the substitution process in action.
Now for the global perspective, more from the EIA.... (bold highlights mine)
It appears evident from the significant investments in preliminary leasing activity in many parts of the world that there is significant international potential for shale gas that could play an increasingly important role in global natural gas markets... In total, the report assessed 48 shale gas basins in 32 countries, containing almost 70 shale gas formations...
The estimates of technically recoverable shale gas resources for the 32 countries outside of the United States represents a moderately conservative ‘risked’ resource for the basins reviewed. These estimates are uncertain given the relatively sparse data that currently exist and the approach the consultant has employed would likely result in a higher estimate once better information is available.
What does all this tell us?
The energy market is working quite well, despite numerous interventions applied by governments.
The diffusion of technological advancements combined with the attendant economies of scale enhances the commercial viability of these projects, which if the EIA is correct, would mean more nations utilizing their natural shale gas resources. This also means reserves will grow as usage grows, enabled by technology.
In short, shale gas is gradually being recognized as an economically valuable energy resource.
Shale gas is probably one of the possible candidates to compete, replace, if not compliment fossil fuel as a major energy source.
Only the markets will say.
Oh, I almost forgot: Please remember changes happen at the margins.
