CAMBRIDGE, Mass., November 14, 2006 – In contrast to a widely discussed theory that world oil production will soon reach a peak and go into sharp decline, a new analysis of the subject by Cambridge Energy Research Associates (CERA) finds that the remaining global oil resource base is actually 3.74 trillion barrels -- three times as large as the 1.2 trillion barrels estimated by the theory’s proponents -- and that the “peak oil” argument is based on faulty analysis which could, if accepted, distort critical policy and investment decisions and cloud the debate over the energy future.
“The global resource base of conventional and unconventional oils, including historical production of 1.08 trillion barrels and yet-to-be-produced resources, is 4.82 trillion barrels and likely to grow,” CERA Director of Oil Industry Activity Peter M. Jackson writes in Why the Peak Oil Theory Falls Down: Myths, Legends, and the Future of Oil Resources. The CERA projection is based on the firm’s analysis of fields currently in production and those yet-to-be produced or discovered.
“The ‘peak oil’ theory causes confusion and can lead to inappropriate actions and turn attention away from the real issues,” Jackson observes. “Oil is too critical to the global economy to allow fear to replace careful analysis about the very real challenges with delivering liquid fuels to meet the needs of growing economies. This is a very important debate, and as such it deserves a rational and measured discourse.”
“This is the fifth time that the world is said to be running out of oil,” says CERA Chairman Daniel Yergin. “Each time -- whether it was the ‘gasoline famine’ at the end of WWI or the ‘permanent shortage’ of the 1970s -- technology and the opening of new frontier areas has banished the specter of decline. There’s no reason to think that technology is finished this time.”
The report emphasizes the importance of focusing on the critical issues. “It is not helpful to couch the debate in terms of a superficial analysis of reservoir constraints. It will be aboveground factors such as geopolitics, conflict, economics and technology that will dictate the outcome.” The report also points to such aboveground questions as timing and openness to investment, infrastructure development, and the impact of technological change on demand for oil.
Undulating Plateau
The new report describes CERA’s liquids supply outlook as “not a view of endless abundance.” However, based on a range of potential scenarios and field-by-field analysis, CERA finds that not only will world oil production not peak before 2030, but that the idea of a peak is itself “a dramatic but highly questionable image.”
Global production will eventually follow an “undulating plateau” for one or more decades before declining slowly. The global production profile will not be a simple logistic or bell curve postulated by geologist M. King Hubbert, but it will be asymmetrical – with the slope of decline more gradual and not mirroring the rapid rate of increase -- and strongly skewed past the geometric peak. It will be an undulating plateau that may well last for decades.
During the plateau period in later decades, according to the CERA analysis, demand growth will likely no longer be largely met by growth in available, commercially exploitable natural oil supplies. Non-traditional or unconventional liquid fuels such as production from heavy oil sands, gas-related liquids (condensate and natural gas liquids), gas-to-liquids (GTL), and coal-to-liquids (CTL) will need to fill the gap.
Critical Issue
CERA argues that understanding the difference between a plateau and a peak followed by a precipitous decline, as well as the timing of events, is critical to the global energy future. “Corporations, governments, and other groups, including nongovernmental organizations, need to have a coherent description of how and when the undulating plateau will evolve so that rational policy and investment choices can be made,” according to the report.
“It is likely that the situation will unfold in slow motion and that there are a number of decades to prepare for the start of the undulating plateau. This means that there is time to consider the best way to develop viable energy alternatives that would eventually provide the bulk of our transport energy needs and ensure that there is a useable production stream of conventional crude for some time to come,” CERA concludes.
