Abstract
It has been found that after introducing two parameters, the Pareto distribution model can accurately describe the statistical characteristics of the observed pool size distributions with progressive increases in exploration maturity. Based on several exploration exampies one may analyze the trend of the distribution parameters with changes in exploration maturity, thus estimate the parent pool size distribution. The proposed generalized Pareto distribution model is a dynamic method that establishes the relationship among the pool size distribution, exploration maturity (human factor), and basin richness (geological factor) ) . This model can be used to estimate pool size, number of pool and to predict the amount of exploration effort of finding those pools in future exploration. The method has been applied to quantitative resource assessments in Songliao basin and Sichuan basin.
