The Future Of Oil

Extreme oil—from the deep Atlantic to the Arctic, from fracking in the U.S. to tar sands in Canada—is replacing dwindling supplies and extending the age of petroleum. But it comes at a heavy economic and environmental cost we may not be able to bear.

THE WATERS OF THE ATLANTIC Ocean 180 miles east of Rio de Janeiro are a cobalt blue that appears bottomless. But it only seems that way. Some 7,000 feet beneath the choppy surface lies the silent sea floor, and below that is 5,000 feet of salt rock, deposited when the continents of South America and Africa went their separate ways 160 million years ago.

Underneath it all is oil. By one count, the pre-salt reservoirs off the central coast of Brazil hold as much as 100 billion barrels of crude; that’s another Kuwait. It’s why former Brazilian President Luiz Inácio Lula da Silva called the pre-salt finds a “gift of God,” and it’s why the massive Cidade de Angra dos Reis floating oil-production facility—operated by Petrobras, Brazil’s state-run oil giant—is anchored in the Atlantic, pumping 68,000 barrels of crude a day from one of the deepest wells in the world. The platform deck is so big you could play the Super Bowl on it, if not for the nest of interlocking pipes and valves that circulate oil, methane, and steam throughout the ship. As I tour the deck in an orange safety jumper, a Petrobras engineer named Humberto Americano Romanus urges me to put a hand to one of the oil pipes. I can feel it pulse like an artery, the oil still warm from the deep heat of the earth. It’s 50 barrels a minute passing through here,” he says over the din of the platform. “That’s a lot of oil.”

But not enough. Demand for oil is still rising—set to grow 800,000 barrels a day in 2012 despite a still sluggish global economy. Meanshile, production from places like Russia, Iran, and Kuwait seems to be plateauing. The rigs that have gathered along the coast of Brazil are drilling deeper than ever before, through layers of salt rock, in some of the most complex and risky operations the industry has ever seen. “This reservoir is very heterogeneous, very challenging,” says Jose Roberto Fagundes Netto, general manager of research and development for Petrobras. “But we know an accident is unacceptable.” A well blowout like the one that caused the BP oil spill in 2010 would be even harder to contain in the deeper pre-salt waters.

This is the new world of extreme oil. Petrobras can af­ford to push the frontiers of offshore drilling because the price of Brent crude, a benchmark used by oil markets, in 2011 averaged $111, the highest average cost since the Drake well in Titusville, Pa., began spewing wealth in 1859, launching the petroleum era. From that time on, even despite J.D. Rockefeller’s attempt to monopolize it, oil has experienced also-year price slide, interrupted by periodic spikes. The prices of all commodities fluctuate, but oil’s irreplaceability—it’s the fuel that makes us go­—ensures that those spikes hurt. In 2011 oil soared in part because of geopolitics, especially the threat that Iran would block the Gulf of Hormuz and cut supplies. That uncertainty contributed to a risk premium of perhaps $20 or more a barrel. A promise by Saudi Arabia in late March to bring spare oil production onto the market has done little to calm prices.

In the U.S., consumers face an extreme-oil paradox. We need more oil to achieve energy independence—and we’re producing it in places like the Bakken shale forma­tion in North Dakota—even as we are using less of it. A combination of recession, conservation, and improved auto efficiency has helped the U. S. shed demand impres­sively. But demand in China, India, and other developing nations has replaced it. Result: plentiful but expensive oil that translates into painfully high gas prices. In 2011 the average cost for a gallon of unleaded was $3.51, the highest on record, up from $2.90 a year before. That takes a chunk out of household budgets and threatens an al­ready underwhelming economic recovery.

Not that long ago, the big worry about fossil fuels was how rapidly supplies were waning. Now new and unconventional sources of oil are filling the gaps. Ul­tra-deepwater reserves like those found off Brazil offer the promise of billions of barrels. Technological break­throughs have unlocked what’s known as tight oil in the shale rock of North Dakota and Texas, reversing what seemed like a terminal decline in U.S. oil production. Alberta’s vast oil sands have given Canada the world’s second largest crude reserves, after Saudi Arabia’s, and offer the U.S. a friendlier crude dealer. As global warm­ing melts the Arctic sea ice, an unexpected dividend is access to tens of billions of barrels of oil in the waters of the far north. “We’ve seen a paradigm shift over the past decade,” says Daniel Yergin, chairman of the research group IHS CERA. “You look at tight oil and oil sands and deepwater, and you see the results.”

Those results could be the problem. While unconven­tional sources promise to keep the supply of oil flowing, it won’t flow as easily as it did for most of the 20th cen­tury. The new supplies are for the most part more expen­sive than traditional oil from places like the Middle East, sometimes significantly so. They are often dirtier, with higher risks of accidents. The decline of major conven­tional oil fields and the rise in demand mean the spare production capacity that once cushioned prices could be gone, ushering in an era of volatile market swings. And burning all this leftover oil could lock the world into dangerous climate change.

Just how dangerous? Oil is responsible for about 40% of the carbon emissions from fossil fuels worldwide, so continued dependence on crude will make it that much more difficult to deal with climate change. And some of those new sources of crude are particularly dirty, in­cluding the much-hyped Canadian oil sands, which can produce as much as 15% to 20% more greenhouse gases than conventional oil. “I’m less concerned about the en­vironmental consequences of pursuing what’s left,” says Michael Klare, an energy expert and the author of The Race for What’s Left. There will be oil, but it will be expen­sive’ dirty, and dangerous.

The Bakken Boom
If you want to find oil in the U.S., or a job, for that mat­ter, head to North Dakota. The Peace Garden State is experiencing a remarkable oil boom in the midst of high gas prices, with production rising from 98,000 barrels a day in 2005 to more than 510,000 barrels by the end of 2011. Thanks to shale oil in the Bakken formation, the petroleum workforce has risen from 5,000 in 2005 to more than 30,000 people. North Dakota’s unemployment rate is the nation’s lowers, 3.2%, and so many would-be roughnecks have flooded the state that workers are housed in temporary “man camps,” like Wild West mining settlements. “You can go straight to those fields and get a good-paying job,” says Scott Tinker, the state geologist of Texas. “The demand is there.”

So is the supply, thanks to innovations in hydraulic fracturing and horizontal drilling that have opened up reserves of oil previously considered unobtainable. Using a process similar to one employed in shale-gas exploration, which ahs flooded the U. S. with cheap natural gas, rigs drill down first and then horizontally into shale layers before fracturing the rock to release the tightly bound oil. “The same massive investment we saw with shale gas is now happening with tight oil,” says Seth Keinman, an analyst with Citigroup who recently wrote a research note on the potential of tight oil. “And it’s going to play out in the same massive way.”

Tight oil has helped revitalize the American drilling industry and it could contribute significantly to global supplies, with the International Energy Agency (IEA) projecting that U.S. tight-oil production could reach 2.4 million barrels a day by 2020.

Thanks as well to greater efficiency. In 2011 the U.S. imported just 45% of the liquid fuels it used, down from a peak of 60% in 2005, and just 1.8 million barrels a day come from the Persian Gulf. If domestic oil production continues to rise, the U.S. could actually approach a goal that has long seemed a political fantasy: energy independence.

But how much more the U.S. will be able to produce is up for debate. While tight-oil reserves are plentiful, wells tend to dry up quickly, which means a lot of drilling is needed to keep the oil flowing. Even if the U.S. can’t achieve energy independence, the oil-sand resources of Canada, already America’s biggest oil supplier, could further reduce imports from the Middle East. High oil prices have boosted investment in the oil sands, and the Energy Informa­tion Administration (EIA), the analytical arm of the U.S. Energy Department, projects that oil-sand production will rise from 1.7 mil­lion barrels a day in 2009 to 4.8 million barrels in 2035—more than Iran’s current output.

So does that mean the return of $2-a-gallon gasoline? Nope. It’s true that reducing oil imports is good for the U.S. economy. Ameri­cans spent $331.6 billion-the size of the entire agriculture industry ­on oil imports last year, up 32% from 2010. Cutting imports keeps that money in the U.S., reducing a trade deficit that hit $560 billion last year. It’s also, of course, good for international oil companies like Shell and Chevron, which are increasingly being squeezed out by massive state-owned companies. You may not like Exxon because of the pump price or its oversize profits, but how much love do you have for autocratic petrostates like Iran or Russia? Exxon’s growth trickles down; the oil-and-gas industry created 9% of all new jobs last year, according to a report by the World Economic Forum, even as oil companies booked multibillion -dollar profits.

But contrary to what the drill-here, drill-now crowd says, oil companies could punch holes in every state and barely make a dent in gasoline prices. Even a more en­ergy independent U.S. can’t control prices, not with a thirsty China competing on the globalized oil market. “Energy security is fine, but it doesn’t have that much meaning in a globalized economy,” says Guy Caruso, a former head of the EIA. “More production adds fungi­bility to the world market, but we’re still vulnerable to shocks in other countries.” The oil the U.S. uses may be American, but that doesn’t mean it will be cheap.

The True Price of Oil
Then there’s the environmental cost. Oil has never ex­actly been clean, but the new sources coming online tend to be more polluting and more dangerous than conven­tional crude. Producing oil from the sands in northern Alberta can be destructive to the local environment, re­quiring massive open-pit mines that strip forests and take years to recover from. The tailings from those mines are toxic. While some of the newer production methods eschew the open-pit mines and instead process the sands underground or in situ, which is much cleaner, they still require additional energy to turn oil sands into usable crude. As a result, a barrel of oil-sand crude usually has a 10% to 15% larger carbon footprint than conventional crude over its lifetime, from the well to the wheels of a car. Given the massive size of the oil-sand reserve—nearly 200 billion recoverable barrels-that’s potentially a lot of carbon. It’s not surprising that environmentalists have loudly opposed the Keystone XL pipeline, which would send 800,000 barrels of oil-sand crude a day to the U.S. “There’s enough carbon there to create a totally different planet,” says James Hansen, a NASA climatolo­gist and activist.

Tight-oil production isn’t as polluting as extracting from oil sands, but it does make use of fracking, which has quickly become the most controversial technique in energy. Fracking fluids contain small amounts of toxic chemicals, and there have been allegations in Pennsylvania—where fracking has been used to produce shale nat­ural gas—that it contaminates groundwater. The federal government is considering stricter regulations on the practice. “The federal rules have loopholes, and the state rules are too weak,” says Amy Mall, a senior policy ana­lyst for the Natural Resources Defense Council. “”There are risks to groundwater, and there are risks to air.” So far, there have been few complaints of water pollution from tight-oil wells in North Dakota and Texas, though both those states have notably oil-industry-friendly attitudes.

If tight-oil production spreads to more densely popu­lated states like Ohio and California, both of which have shale plays, we could see those states gripped by the same controversies that have come with shale gas in Pennsyl­vania and New York. Sparse North Dakota is struggling to deal with the sudden influx of workers and equipment as well as the air pollution that results from tight-oil pro­duction. Even the oil industry is realizing that it needs to assuage public concerns. “We cannot ignore parts of the public that don’t trust our industry and our ability to operate safely,” Statoil CEO Helge Lund said at a 2011 energy conference. “This is a fundamental issue affect­ing us all”

The offshore drilling in Brazil’s pre-salt reservoirs and in the Arctic waters being opened up by climate change is cleaner, but as seen with the Deepwater Hori­zon spill, if something goes wrong, it means catastrophe. If you think cleaning up an oil spill in the Gulf of Mexico was tough, try doing it in the remote, forbidding Arctic. But even greater than the immediate environmental danger posed by unconventional oil is the larger risk to the climate. One of the expected consolations of peak oil was the assumption that running out of conventional crude would finally force us to develop carbon-free alter­natives such as wind and solar. Extreme oil means there will still be enough—more than 1 trillion barrels by one estimate—to keep cooking the planet if we decide to burn it all. Deborah Gordon, an expert at the Carnegie En­dowment for International Peace, says that “21st-century oil is not 20th-century oil. New, unconventional oils are going to recarbonize global petroleum supplies.”

So this is the future of oil: as costly as it is polluting. But if we can’t ensure cheap oil, we can become more resilient when fuel becomes expensive. That requires continued improvements in energy efficiency. The U.S. has made some strides recently in that area (new vehicles get better mileage now than ever before), but it still lags behind the rest of the world. Obama’s push to increase corporate average fuel-efficiency standards for vehicles to 55 miles per gallon by 2025 is vital. After all, doubling the mileage of your car is the equivalent of cutting the price of gasoline in half. Other kinds of energy alterna­tives must be developed to break the monopoly of crude, for environmental and economic reasons. Diversifying your energy supply is as wise as diversifying your port­folio. “We’ve got to develop every source of American en­ergy, not just oil and gas but wind power and solar power, nuclear power and biofuels,” Obama said in a speech in March 2011. “That’s the only solution to this challenge.”

From Brazil to Bismarck, human ingenuity (and tens of billions of dollars in investment) has extended the age of oil, as well as our anxiety about it. There’s no reason the same formula can’t eventually bring it to an end-on our terms.
