Research Methods of Main Parameter Sensitivity Differences in China’s Dynamic Oil and Gas Reserve Estimation under SEC Standards

International oil and gas companies listed in New York must publish the information of reserves under SEC (United States Securities Exchange Commission) standards every year. For greatly improving reserve, reserve value substitution rate, this article not only equations have been determined but also models established. The verified as correct. Based on these models, multivariate function calculus method, limit method recurrence adopted to research parameter sensitivity differences rules, adjustment directions, degrees linkage rules. is significant, because there are great between China’s management mode, estimation system financial system. It just that cause frequent parameters during process submissions each As a result, reaches some conclusions. Above all, has clarified quantitative conditions lead initial production begin stronger weaker than price exponential, hyperbolic harmonic decline types. Furthermore, common exponential Moreover, rules found most significant whose least will largest increase. In addition, disclose expand analysis took previous statistical mapping main method.
