A novel technique for forecasting the supply and extraction life-cycles of a depleting fossil fuel resource has been developed. The supply side utilises a skewed-normal production-profile model that yields a better representation than earlier approaches. A simple model for extrapolating crude oil and natural gas demands has also been devised: it is based on the so-called modified logit function . The predicted crude oil and natural gas balances, for the period up to ad 2010, indicate the disparities between the rates of indigenous production and future consumption for Denmark. These forecasts depend on the present estimates of the remaining crude oil and natural gas reserves. It will consequently be necessary to revise periodically the present projection as more reliable reserves estimates become available.NOTATIONA Coefficient in the skewed-normal production-profile equationDKr Danish kronern Shape factor in the skewed-normal production-profile equationP Rate of production from the resource reservoir (Mtoe/annum)R Remaining reserves (Mtoe)t Period from the start time, t z e r o (years)t m a x Year of peak rate of productiont z e r o Year immediately before large-scale production occurredt ∞ Period of exhaustion of the resource, i.e. since t z e r o (years)URR Ultimately recoverable part of the resource (Mtoe)URR c Ultimately recoverable part of the resource, as calculated from the presented equations (Mtoe)URR e Ultimately recoverable part of the resource, as estimated on technical and economic grounds (Mtoe)α Peak positioning factor for the skewed-normal production-profile equation (=n/t m a x )
