About 25% of the crude oil and 80% of the natural gas imported into the U. S. come Canada. For how long? Not very.
Petroleum and Natural Gas Watch, November 2, 2006, Vol. 5, Number 8
Sating America's prodigious energy appetite depends on the continued availability of Canadian energy sources. About 25% of the crude oil and 80% of the natural gas imported into the United States come from our very accommodating neighbor to the north. More than half of the fuel pumped out of Canadian wells heads south to keep us Yankees warm and happily tooling about on our highways.
Even though the Canadian economy is no less dependent on hydrocarbon energy than ours, Canada has been drilling as many wells as necessary to keep the high-maintenance American economy humming. If this pedal-to-the-metal production policy were applied to a non-strategic product like, say, maple syrup, few people would care about the consequences. But there is nothing on the horizon to replace the nonrenewable high-density energy sources that Canada so generously sends our way.
This begs the question: how long can Canada go on behaving like America's most compliant energy colony?
Not very long, according to David Hughes, a petroleum geologist with the Geological Survey of Canada. Speaking before the World Peak Oil Conference held in Boston last week, Hughes painted a remarkably pessimistic picture of Canada's energy future, especially regarding natural gas.
Despite record drilling activity, natural gas extraction volumes have slipped from the peak set in 2002, and output per well is now declining at an annual rate of 28%. Put another way, just to keep the output from declining this decade, producers must complete nearly one-third more wells in 2007 than in this year, and then repeat that achievement in 2008, 2009 and 2010.
That would be a daunting challenge even if there were rigs and drilling crews standing by. As it now stands, there is no spare capacity of this sort anywhere in North America.
With only eight years of proven reserves left in Canada, Hughes suspects that natural gas output is about to fall off a cliff. Barring a miracle or two, Canada will soon experience challenges in providing for its own citizens, let alone producing surplus volumes bound for American furnaces.
A potentially wrenching resource conflict is now brewing on our continent, thanks to the North American Free Trade Agreement (NAFTA), under which Canada effectively gave up sovereignty over its fossil energy inheritance. As a signatory, Canada is prohibited from cutting back energy exports, even in the event of a domestic supply crunch. But how long would Canada honor its obligations under NAFTA if doing so resulted in its citizens freezing to death? American policymakers would be wise to explore how that scenario might play out.
If that weren't enough, natural gas is also the key to expanding the production of oil from the tar sands of northern Alberta, the only oil-producing region left in North America that can increase output. It is the only available fuel for producing the pressurized steam needed to separate bitumen, a low-grade oil, from sand. Shrinking natural gas supplies would quickly reduce the flow of bitumen into the U.S., further complicating Canada's energy dilemma.
The irony of sacrificing a premium energy source to make more low-grade fuel for export was not lost on Hughes, who closed with a quote from a Canadian energy executive. "Using natural gas to produce oil from tar sands is akin to turning gold into lead."
