Method for Estimation of Gas Well Risk Productivity

Abstract

Abstract: Gas well productivity estimation is an important method for determination of open flow potential and working system, prediction of production performance and study of related gas reservoir engineering. Using its probability statistical approach, this paper analyzes the uncertainty distribution of net pay thickness and permeability in the reservoir, researches the impact of geologic parameter uncertainty on gas well binomial productivity equation. Case study shows that considering the geologic parameter uncertainty allows the gas well productivity estimation to be more precise, thus decreasing the possible risks in gas pool development.

Key words: gas well, productivity estimation, risk, calculation method
