  2. Predicting the timing of peak oil - Wikipedia

    In 1956, Hubbert confined his peak oil prediction to that crude oil "producible by methods now in use." [13] By 1962, however, his analyses included future improvements in exploration and production. [14] All of Hubbert's analyses of peak oil specifically excluded oil manufactured from oil shale or mined from oil sands. A 2013 study predicting ...

    The standard Hubbert curve.For applications, the x and y scales are replaced by time and production scales. U.S. Oil Production and Imports 1910 to 2012. In 1956, Hubbert proposed that fossil fuel production in a given region over time would follow a roughly bell-shaped curve without giving a precise formula; he later used the Hubbert curve, the derivative of the logistic curve, [6] [7] for ...

    These methods are often more time-consuming than entering the values into a VCF calculator; however, due to the variance in methodology and computation of constants, the tables published by the American Petroleum Institute are preferred when dealing with the purchase and sale of crude oil and residual fuels.

    Crude oil production has since risen sharply from 2009 through 2014, so the rate of US oil production in October 2014 was 81% higher than the average rate in 2008. [ 12 ] The actual U.S. production curve deviates from Hubbert's 1956 curve in significant ways:

  6. Forecast either to existing data (static forecast) or "ahead" (dynamic forecast, forward in time) with these ARMA terms. Apply the reverse filter operation (fractional integration to the same level d as in step 1) to the forecasted series, to return the forecast to the original problem units (e.g. turn the ersatz units back into Price).

  7. Fan chart (time series) - Wikipedia

    en.wikipedia.org/wiki/Fan_chart_(time_series)

    In time series analysis, a fan chart is a chart that joins a simple line chart for observed past data, by showing ranges for possible values of future data together with a line showing a central estimate or most likely value for the future outcomes. As predictions become increasingly uncertain the further into the future one goes, these ...

  8. Demand sensing - Wikipedia

    en.wikipedia.org/wiki/Demand_sensing

    Demand sensing is a forecasting method that uses artificial intelligence and real-time data capture to create a forecast of demand based on the current realities of the supply chain. [ 1 ] [ 2 ] Traditionally, forecasting accuracy was based on time series techniques which create a forecast based on prior sales history and draws on several years ...

  9. Box–Jenkins method - Wikipedia

    en.wikipedia.org/wiki/Box–Jenkins_method

    In time series analysis, the Box–Jenkins method, [1] named after the statisticians George Box and Gwilym Jenkins, applies autoregressive moving average (ARMA) or autoregressive integrated moving average (ARIMA) models to find the best fit of a time-series model to past values of a time series.
