1. Models of Canadian Oil and Gas Prices
2. Modelling Risk and Value in Unconventional Oil Play
1. In most oil and gas economics, the biggest uncertainty is the commodity price. To provide this information, many experts produce very detailed price forecasts. These forecasts tend to follow very smooth trends. Unfortunately, both recent and past events have shown that hydrocarbon prices can change very rapidly. As well, several competing trends can be found in oil and gas prices. Long-term historical data indicates that hydrocarbon prices tend to revert back to historical averages. However, short-term price fluctuations are unpredictable. To address this need, a price fluctuation model has been developed for the Canadian oil industry. A random walk model with mean-reversion was developed and tuned to fit Canadian hydrocarbon prices. Starting with the current spot price, the model will generate a random but equiprobable prediction of future prices. The model can be used as input into a Monte-Carlo simulation. Alternately, the model can be run multiple times in order to generate "high", "low", and "expected" price predictions.
2. In the current lower commodity price environment, characterizing and quantifying risk and understanding value expectations are of great importance to producers, investors and creditors. It is common practice in industry to exclusively use deterministic methods in well and field performance prediction and ultimate recoverable volume estimation, as well as in commodity price forecasting and cash flow forecasting. This can lead to an incomplete understanding of value expectations, and often, an underestimation of the breadth of possible outcomes. We discuss a general probabilistic workflow for characterizing risk and value in unconventional resource plays, including stochastic decline analysis and price forecasting methods, geostatistical considerations, and suitable performance metrics to inform decisions. To illustrate some of the benefits this method offers over conventional deterministic methods, we pose several relevant example questions relating to risk and value assessment and proceed to answer them upon completion of this process.
