This study presents a set of production type curves for CBM reservoirs that would help the producers to predict the production from their CBM wells. As a consequence, the producers would be able to make better, more informed decisions regarding the CBM resources in the region. A reservoir model that incorporates the unique flow and storage characteristics of CBM reservoirs was employed in this study to develop the type curves. The type curves provide a reliable tool to predict the production performance of CBM reservoirs during dewatering phase. The application and issues concerning the production performance of CBM reservoirs are also discussed.;In order to achieve the objective of this study, four steps were performed: (a) Development of a base model for Coalbed methane production in Northern Appalachian, (b) development and verification of the dimensionless groups for water production type curves, (c) generation of the CBM water production type curve, and (d) validation of the CBM water production type curve.;A modified correlation for peak gas rate estimation was also proposed as an alternative to forecast gas production along with a correlation for computing initial (maximum) water production rate.
