The Canadian Oil Boom  

Posted by Big Gav in ,

Next month's edition of National Geographic has an article on the tar sands of Canada - The Canadian Oil Boom. How long the boom lasts if the current downturn continues is questionable of course. In the same issue is an article on Energy Conservation.

In Boucher's memory, though, the change begins that day in 1963, on the long trail his grandfather used to set his traps, near a place called Mildred Lake. Generations of his ancestors had worked that trapline. "These trails had been here thousands of years," Boucher said one day last summer, sitting in his spacious and tasteful corner office in Fort McKay. His golf putter stood in one corner; Mozart played softly on the stereo. "And that day, all of a sudden, we came upon this clearing. A huge clearing. There had been no notice. In the 1970s they went in and tore down my grandfather's cabin—with no notice or discussion." That was Boucher's first encounter with the oil sands industry. It's an industry that has utterly transformed this part of northeastern Alberta in just the past few years, with astonishing speed. Boucher is surrounded by it now and immersed in it himself.

Where the trapline and the cabin once were, and the forest, there is now a large open-pit mine. Here Syncrude, Canada's largest oil producer, digs bitumen-laced sand from the ground with electric shovels five stories high, then washes the bitumen off the sand with hot water and sometimes caustic soda. Next to the mine, flames flare from the stacks of an "upgrader," which cracks the tarry bitumen and converts it into Syncrude Sweet Blend, a synthetic crude that travels down a pipeline to refineries in Edmon­ton, Alberta; Ontario, and the United States. Mildred Lake, meanwhile, is now dwarfed by its neighbor, the Mildred Lake Settling Basin, a four-square-mile lake of toxic mine tailings. The sand dike that contains it is by volume one of the largest dams in the world.

Nor is Syncrude alone. Within a 20-mile radius of Boucher's office are a total of six mines that produce nearly three-quarters of a million barrels of synthetic crude oil a day; and more are in the pipeline. Wherever the bitumen layer lies too deep to be strip-mined, the industry melts it "in situ" with copious amounts of steam, so that it can be pumped to the surface. The industry has spent more than $50 billion on construction during the past decade, including some $20 billion in 2008 alone. Before the collapse in oil prices last fall, it was forecasting another $100 billion over the next few years and a doubling of production by 2015, with most of that oil flowing through new pipelines to the U.S. The economic crisis has put many expansion projects on hold, but it has not diminished the long-term prospects for the oil sands. In mid-November, the International Energy Agency released a report forecasting $120-a-barrel oil in 2030—a price that would more than justify the effort it takes to get oil from oil sands.

Nowhere on Earth is more earth being moved these days than in the Athabasca Valley. To extract each barrel of oil from a surface mine, the industry must first cut down the forest, then remove an average of two tons of peat and dirt that lie above the oil sands layer, then two tons of the sand itself. It must heat several barrels of water to strip the bitumen from the sand and upgrade it, and afterward it discharges contaminated water into tailings ponds like the one near Mildred Lake. They now cover around 50 square miles. Last April some 500 migrating ducks mistook one of those ponds, at a newer Syncrude mine north of Fort McKay, for a hospitable stopover, landed on its oily surface, and died. The incident stirred international attention—Greenpeace broke into the Syncrude facility and hoisted a banner of a skull over the pipe discharging tailings, along with a sign that read "World's Dirtiest Oil: Stop the Tar Sands."
