Application of stochastic modeling to oil and gas reserve calculation

Based upon stochastic modeling technology is a method of oil and gas reserve calculation. The difficulty in correctly acquiring parameters during the reserve calculation of complex reservoir by the traditional volume method is avoided when using immediate calculating method by stochastic grid model of the reserve parameters. Several values of reserves got through this method are Monte-carlo realizations that obey a certain distribution of statistical probability. A probability distribution curve of reserves can be got based on processing the results by constant probability statistics, and the reserve estimate can be made by the characteristic value of the curve. The application shows that the reserve calculated through this method is more objective and dependable.
