M. King Hubbert, the 'Peak Oil' Fallacy, and U.S. Energy Policy

Using innovative concepts related to U.S. crude oil production and reserves data, Marion King Hubbert generated prescient and unwelcome forecasts in 1956, and again in 1962, that annual U.S. crude oil production would peak in the late 1960s or early 1970s at around 3 billion bbl, and decline thereafter, implying growing American dependence on imported oil. Hubbert estimated that ultimate domestic crude oil production would total about 200 billion bbl. These forecasts brought him into sharp conflict with the U.S. Geological Survey’s Vincent E. McKelvey throughout the 1960s, and continuing well into the 1970s, even after McKelvey became Director of U.S. Geological Survey in 1971. Under McKelvey’s leadership, the U.S. Geological Survey had consistently estimated that domestic crude oil resources were as much as three times larger than Hubbert’s forecasts—as much as 590 billion barrels—sufficient “to meet projected consumption through and beyond” the end of the 20th century. Their increasingly acrimonious dispute reached out well beyond the American scientific community, and spilled over into National energy policy. When U.S. crude oil production peaked in 1970 at about 3.2 billion barrels, Hubbert’s bold forecast seemed to be confirmed, and he was hailed as a prophet. McKelvey was fi red in 1977 by the incoming Carter administration, and Hubbert’s forecasts were used as a basis to deny government subsidies to domestic E&P companies (“if the resource endowment is not there, it’s not worth paying companies to try and look for it”), and to develop alternative energy sources, including U.S. oil shale deposits. Working under the protection of U.S. Sen. Henry ‘Scoop’ Jackson, Hubbert then developed analogous estimates of future domestic natural gas production, as well as global crude oil production. He forecast that U.S. natural gas production would peak in 1975, at about 18 trillion cubic feet per year, with a total production of about 1050 trillion cubic feet per year. Hubbert also predicted that global oil production would peak at an annual rate of about 40 billion barrels in about 1995, with ultimate production of about 2000 billion barrels. These forecasts have long since been eclipsed by actual production, and discovered reserves. Examined from the vantage point of nearly 40 years, all of Hubbert’s forecasts are clearly too pessimistic, primarily because he failed to anticipate that technological breakthroughs would make E&P in hostile environments possible, and that new drilling and stimulation technologies would allow reservoirs to be developed in rocks then thought to be incapable of production. This experience bears naturally on formulation of U.S. energy policy, which has been absent for about 30 years, and is urgently needed if the U.S. is to continue as a global leader in the 21st century. Continued large trade deficits for imported oil threaten the still-fragile U.S economy. Most Americans do not grasp how closely energy consumption correlates with economic prosperity. U.S. natural gas production and reserves have been increasing since 1986 and are projected to continue rising, and, in 2009, U.S. crude oil production increased for the first time since 1971, with continued rising production forecast years into the future. Secure supply of motor fuels is America’s greatest short-term energy priority, whereas increasing electricity supply is the greatest long-term priority. Conservation
