Natural Gas: Alternative Energy Of The Future

The Economist has this nice article about natural gas.

The article goes to show that the world isn't running out of energy. It's just a matter of markets aided by technology, adapting to the current conditions.

Here's an excerpt, (all bold highlights mine)

``The source of America’s transformation lies in the Barnett Shale, an underground geological structure near Fort Worth, Texas. It was there that a small firm of wildcat drillers, Mitchell Energy, pioneered the application of two oilfield techniques, hydraulic fracturing (“fracing”, pronounced “fracking”) and horizontal drilling, to release natural gas trapped in hardy shale-rock formations. Fracing involves blasting a cocktail of chemicals and other materials into the rock to shatter it into thousands of pieces, creating cracks that allow the gas to seep to the well for extraction. A “proppant”, such as sand, stops the gas from escaping. Horizontal drilling allows the drill bit to penetrate the earth vertically before moving sideways for hundreds or thousands of metres.

``These techniques have unlocked vast tracts of gas-bearing shale in America. Geologists had always known of it, and Mitchell had been working on exploiting it since the early 1990s. But only as prices surged in recent years did such drilling become commercially viable. Since then, economies of scale and improvements in techniques have halved the production costs of shale gas, making it cheaper even than some conventional sources.
More from the Economist,

``The Barnett Shale alone accounts for 7% of American gas supplies. Shale and other reservoirs once considered unexploitable (coal-bed methane and “tight gas”) now meet half the country’s demand. New shale prospects are sprinkled across North America, from Texas to British Columbia. One authority says supplies will last 100 years; many think that is conservative. In 2008 Russia was the world’s biggest gas producer; last year, with output of more than 600 billion cubic metres, America probably overhauled it. North American gas prices have slumped from more than $13 per million British thermal units in mid-2008 to less than $5. The “unconventional”—tricky and expensive, in the language of the oil industry—has become conventional.

``The availability of abundant reserves in North America contrasts with the narrowing of Western firms’ oil opportunities elsewhere in recent years. Politics was largely to blame, as surging commodity prices emboldened resource-rich countries such as Russia and Venezuela to restrict foreign access to their hydrocarbons. “Everyone would like to find more oil,” says Richard Herbert, an executive at Talisman Energy, a Canadian firm using a conventional North Sea oil business to finance heavy investment in North American shale. “The problem is, where do you go? It’s either in deep water or in countries that aren’t accessible.” This is forcing big oil companies to get gassier."

My comments:

As we have repeatedly said, politics has been the fundamental reason for the elevated prices in oil, caused mainly by geological restrictions or limited access (mentioned by the article) combined with artificial demand from inflationism and or policies, such as subsidies (not mentioned in the article).

Nevertheless, because people adjust to the circumstances they are faced with, such as the pain of higher prices and political constrains, the perpetual desire to satisfy human needs makes possible for ingenuity to pave way for innovative technology which would allow for more access to supplies or substitution.

In the case of natural gas, since there is a recognition, out of the existing technologies, of the abundance of reserves, higher oil prices will likely compel producers to compete to convert erstwhile uneconomical resources into utilizable reserves, ergo "forcing big oil companies to get gassier" as the article mentioned.

And if successful, which I am optimistic of, this will have a spillover effect to the midstream (processing, storage, marketing and transportation) and the downstream (retail outlets, derivative products, etc...). In other words, part of the transformation would likely see global transportation evolve to natural gas as default fuel.

So in the future, we should expect natural gas to also play a big role in the transition to diversify energy sources.

The following chart caught my eye. If the technology to access shale oil becomes universally commercial, guess where the bulk of reserves are?

In Asia Pacific!
