摘要：
The authors present a rigorous method to analyze and interpret production rate and pressure data of low-permeability gas wells using type curves. The method is based on the type curve analysis method presented by Blasingame et al. (1991), but imports the wellbore storage coefficient, which influences the flow behavior of low-permeability gas wells significantly, for the first time. This work fills a significant void in the inventory of decline curve type curves, and the method is applicable to production analysis for cases taken from low-permeability gas wells.
