【Abstract】 The properties of volatility in the model for petroleum real options and the role of volatility in calculation of petroleum option values were discussed. A practical model for estimating the volatilities in the different stages of petroleum real options was presented. The model fits the facts of petroleum industry and is easily operated. On the basis of traditional net present value method and Monte Carlo theory, a method for calculating the stage volatilities in the petroleum real option model was given. The petroleum production and market oil price were considered as two stochastic factors in the model. The analysis results demonstrate the validity of the method.更多还原
