On Applying Stochastic Simulation Technique to Reservoir Prediction

Stochastic simulation is a reservoir prediction technique based on geostatistics.Joint simulation of drilling information and impedance inversion contributes to enhancing predicted accuracy,which is suitable for the initial and late-mid stage of progressive exploration and development.Based on the analysis of reservoir log response and physical parameter and the analysis of histogram and variance,the application selects reasonable inversion parameter and goes ahead with stochastic simulation for predicting regularity of reservoir distribution.This shows that stochastic simulation technique contributes to improving reservoir inversion resolution.
