Summary/Abstract There is a lively debate between 'concerned' and 'unconcerned' analysts regarding the future availability and affordability of oil. We critically examine two interrelated and seemingly plausible arguments for an unconcerned view: (1) there is a growing amount of remaining reserves; (2) there is a large amount of oil with a relatively low average production cost. These statements are unconvincing on both theoretical and empirical grounds. Oil availability is about flows rather than stocks, and average cost is not relevant in the determination of price and output. We subsequently implement a bottom-up model of regional oil production with micro-foundations in both natural science and economics. An oil producer optimizes net present value under the constraints of reservoir dynamics, technological capacity and economic circumstances. Optimal production profiles for different reservoir drives and economic scenarios are derived. The field model is then combined with a discovery model of random sampling from a lognormal field size-frequency distribution. Regional discovery and production scenarios are generated. Our approach does not rely on the simple assumptions of top-down models such as the Hubbert curve - however it leads to the same qualitative result that production peaks when a substantial fraction of the recoverable resource remains in-ground.

Global oil depletion: a review of the evidence / Sorrell, Steve; Speirs, Jamie; Bentley, Roger; Brandt, Adam   Journal Article
Sorrell, Steve Journal Article

Publication 2010.
Summary/Abstract Within the polarised and contentious debate over future oil supply a growing number of commentators are forecasting a near term peak and subsequent decline in production. But although liquid fuels form the foundation of modern industrial economies, the growing debate on 'peak oil' has relatively little influence on energy and climate policy. With this in mind, the UK Energy Research Centre (UKERC) has conducted an independent, thorough and systematic review of the evidence, with the aim of establishing the current state of knowledge, identifying key uncertainties and improving consensus. The study focuses upon the physical depletion of conventional oil in the period to 2030 and includes an in-depth literature review, analysis of industry databases and a detailed comparison of global supply forecasts. This Communication summarises the main findings of the UKERC study. A key conclusion is that a peak of conventional oil production before 2030 appears likely and there is a significant risk of a peak before 2020.

Oil futures: a comparison of global supply forecasts / Sorrell, Steve; Miller, Richard; Bentley, Roger; Speirs, Jamie   Journal Article
Sorrell, Steve Journal Article
0 Rating(s) & 0 Review(s)
Publication 2010.
Summary/Abstract This paper compares and evaluates fourteen contemporary forecasts of global supply of conventional oil and provides some observations on their relative plausibility. Despite the wide range of modelling approaches used and multiplicity of assumptions made, it is shown that forecasts can be usefully compared along two dimensions, namely: shape of future production profile and assumed or implied ultimately recoverable resource of conventional oil. Other differences between forecasts are either secondary or are components of these two parameters. The paper shows how large differences in the assumed size of the resource make relatively little difference to the timing of a global peak in conventional oil production. It also examines the impact of rates of discovery, reserves growth and depletion on the forecast date of peak and shows how forecasts that delay this peak until beyond 2030 rest on assumptions that are at best optimistic and at worst implausible.
