Abstract

Before developing and producing a shale gas resource, it is critical to research estimated ultimate recovery (EUR). This research splits shale gas well production into five flow stages, to better understand the variables influencing EUR following shale gas fracturing and qualitatively evaluate the effect degree of each element on EUR. We fully examine contemporary research on the influencing variables of EUR following shale gas fracturing from three perspectives: geology, engineering, and production, and explain in detail 13 major regulating parameters impacting EUR in different flow phases. Based on the analytic hierarchy process (AHP), an  evaluation model for the primary regulating elements of EUR following shale gas fracturing has been constructed. To test the novel model, actual data from  production wells in a shale gas field in China was used. The optimal well for the current production system after shale gas fracturing is determined, and suggestions and improvement directions for the remaining gas wellsâ production systems are proposed.
