Coalbed methane is an unconventional gas resource that consists on methane production from the coal seams. The unique coal characteristic results in a dual-porosity system. CBM reservoir performance is also influenced by the interrelationship of reservoir, geologic, and operation parameters. Coalbed methane production data is considered a complex and difficult to analyze especially at the early stages of the recovery.;This study was conducted to develop a simple and reliable tool to predict the performance of CBM in The Northern Appalachian Basin. To achieve this objective, four steps were performed. A unique set of gas production type curves for coalbed methane was developed as a simple and economical tool for small producer to evaluate economic feasibility, increase recovery, and maximize efficiency. A correlation for peak gas rate estimation was also proposed as an alternative to forecast gas production without having production data. This approach was performed as a contribution to the development and growth of gas reservoirs in the Northern Appalachian Basin.
