Abstract

This paper presents the development and application of a production data analysis software that can analyze and forecast the production performance and reservoir properties of shale gas wells. The theories used in the study were based on the analytical and empirical approaches. Its reliability has been con- firmed through comparisons with a commercial software. Using transient data relating to multi-stage hydraulic fractured horizontal wells, it was confirmed that the accuracy of the modified hyperbolic method showed an error of approximately 4% compared to the actual estimated ultimate recovery (EUR). On the basis of the developed model, reliable productivity forecasts have been obtained by analyzing field production data relating to wells in Canada. The EUR was computed as 9.6 Bcf using the modified hyperbolic method. Employing the Pow Law Exponential method, the EUR would be 9.4 Bcf. The models developed in this study will allow in the future integration of new analytical and empirical theories in a relatively readily than commercial models.
