Oil Runs Through It...for Now: Shaybah, one of Saudi Arabia's oil fields, which all told can produce 10.5 million barrels of oil a day. The Saudis say they can boost production to 12.5 million barrels a day, or 15 million, or more. But there is a limit to how much you can ask of the earth, and it is fast approaching, some experts say.

"One thing is clear," warns Chevron, the second-largest American oil company, in a series of new advertisements, "the era of easy oil is over."

In the past several years, the gap between demand and supply, once considerable, has steadily narrowed, and today is almost negligible. The consequences of an actual shortfall of supply would be immense. If consumption begins to exceed production by even a small amount, the price of a barrel of oil could soar to triple-digit levels. This, in turn, could bring on a global recession, a result of exorbitant prices for transport fuels and for products that rely on petrochemicals -- which is to say, almost every product on the market. The impact on the American way of life would be profound: cars cannot be propelled by roof-borne windmills. The suburban and exurban lifestyles, hinged to two-car families and constant trips to work, school and Wal-Mart, might become unaffordable or, if gas rationing is imposed, impossible. Carpools would be the least imposing of many inconveniences; the cost of home heating would soar -- assuming, of course, that climate-controlled habitats do not become just a fond memory.

But will such a situation really come to pass? That depends on Saudi Arabia. To know the answer, you need to know whether the Saudis, who possess 22 percent of the world's oil reserves, can increase their country's output beyond its current limit of 10.5 million barrels a day, and even beyond the 12.5-million-barrel target it has set for 2009. (World consumption is about 84 million barrels a day.) Saudi Arabia is the sole oil superpower. No other producer possesses reserves close to its 263 billion barrels, which is almost twice as much as the runner-up, Iran, with 133 billion barrels. New fields in other countries are discovered now and then, but they tend to offer only small increments. For example, the much-contested and as-yet-unexploited reserves in the Alaska National Wildlife Refuge are believed to amount to about 10 billion barrels, or just a fraction of what the Saudis possess.

Until quite recently, the only reason to fear a shortage was if a boycott, war or strike were to halt supplies. Few people imagined a time when supply would dry up because of demand alone. But a steady surge in demand in recent years -- led by China's emergence as a voracious importer of oil -- has changed that.


{excerpt}
This demand-driven scarcity has prompted the emergence of a cottage industry of experts who predict an impending crisis that will dwarf anything seen before. Their point is not that we are running out of oil, per se; although as much as half of the world's recoverable reserves are estimated to have been consumed, about a trillion barrels remain underground. Rather, they are concerned with what is called ''capacity'' -- the amount of oil that can be pumped to the surface on a daily basis. These experts -- still a minority in the oil world -- contend that because of the peculiarities of geology and the limits of modern technology, it will soon be impossible for the world's reservoirs to surrender enough oil to meet daily demand.


{excerpt}
The popular notion of reservoirs as underground lakes, from which wells extract oil like straws sucking a milkshake from a glass, is incorrect. Oil exists in drops between and inside porous rocks. A new reservoir may contain sufficient pressure to make these drops of oil flow to the surface in a gusher, but after a while -- usually within a few years and often sooner than that -- natural pressure lets up and is no longer sufficient to push oil to the surface. At that point, ''secondary'' recovery efforts are begun, like pumping water or gas into the reservoirs to increase the pressure.


{excerpt}
This process is unpredictable; reservoirs are extremely temperamental. If too much oil is extracted too quickly or if the wrong types or amounts of secondary efforts are employed, the amount of oil that can be recovered from a field can be greatly reduced; this is known in the oil world as ''damaging a reservoir.'' A widely cited example is Oman: in 2001, its daily production reached more than 960,000 barrels, but then suddenly declined, despite the use of advanced technologies. Today, Oman produces 785,000 barrels of oil a day. Herman Franssen, a consultant who worked in Oman for a decade, sees that country's experience as a possible lesson in the limits of technology for other producers that try to increase or maintain high levels of output. ''They reached a million barrels a day, and then a few years later production collapsed,'' Franssen said in a phone interview. ''They used all these new technologies, but they haven't been able to stop the decline yet.''

"The Stone Age didn't end for lack of stone, and the oil age will end long before the world runs out of oil."

{excerpt}
... the need to produce more oil is coming from two directions. Most obviously, demand is rising; in recent years, global demand has increased by two million barrels a day. (Current daily consumption, remember, is about 84 million barrels a day.) Less obviously, oil producers deplete their reserves every time they pump out a barrel of oil. This means that merely to maintain their reserve base, they have to replace the oil they extract from declining fields. It's the geological equivalent of running to stay in place.

"You look at the globe and ask, 'Where are the big increments?' and there's hardly anything but Saudi Arabia," he said. "The kingdom and Ghawar field are not the problem. That misses the whole point. The problem is that you go from 79 million barrels a day in 2002 to 82.5 in 2003 to 84.5 in 2004. You're leaping by two million to three million a year, and if you have to cover declines, that's another four to five million." In other words, if demand and depletion patterns continue, every year the world will need to open enough fields or wells to pump an additional six to eight million barrels a day -- at least two million new barrels a day to meet the rising demand and at least four million to compensate for the declining production of existing fields. "That's like a whole new Saudi Arabia every couple of years," Husseini said. "It can't be done indefinitely. It's not sustainable."


{excerpt}
Husseini, for one, doesn't buy that approach. "Everybody is looking at the producers to pull the chestnuts out of the fire, as if it's our job to fix everybody's problems," he told me. "It's not our problem to tell a democratically elected government that you have to do something about your runaway consumers. If your government can't do the job, you can't expect other governments to do it for them."

When a crisis comes -- whether in a year or 2 or 10 -- it will be all the more painful because we will have done little or nothing to prepare for it.
