TRANSCRIPT
Long Term World Oil Supply(A Resource Base/Production Path Analysis)
Executive Summary
- These pages summarize a recent EIA presentation on when world conventional oil production will peak and the effect of different estimates of the world conventional oil resource base.
- A larger resource base generally leads to a later production peak. World oil resource base estimates have trended upward over the years, from 600 billion barrels estimated in the early 1940’s to as high as 3,900 billion barrels estimated this year by the U.S. Geological Survey (USGS).
- To illustrate the important factors affecting estimates of the peak production year, EIA postulated 12 scenarios based on three current USGS world conventional oil resource base estimates (2,248, 3,003 and 3,896 billion barrels - corresponding to high, mean and low probabilities of occurrence) and four world oil production annual growth rates (0, 1, 2 and 3 percent.)
- Using a relatively simple algorithm, peak production years were estimated. The peak production year estimates ranged from 2021 to 2112 across the 12 scenarios. For example, using the USGS mean (expected) resource base estimate (3,003 billion barrels) and an annual production growth rate of 2 percent (similar to the current rate), the estimated peak production year is 2037.
- EIA’s estimates for production peaks occur later than those generated by other analysts, some of whom predicted the production peak will occur as early as 2004. EIA’s analysis indicates instead that world conventional oil production may increase two decades or more before it begins to decline.
Executive Summary (Continued)
Executive Summary (Continued)
- EIA’s relative optimism is based on:
(1) use of the current USGS world conventional oil resource estimates, which are both larger and more technically sound than past resource estimates used by others, and
(2) use of a methodology for estimating the post-peak production path that is based on the reserve to production (R/P) ratio observed in the United States since oil production peaked in 1970.
- Other factors, e.g., choice of different production curve hypotheses, market dynamics, technological advances, and economic policies, could change the results, perhaps substantially.
