Studies on the Estimation and Prospective Recovery of Coal Bed Methane from Raniganj Coalfield, India

Faster depletion of liquid hydrocarbons reserves makes coal bed methane a potential energy source. In the present investigation, coal samples were collected from a coal bed methane reservoir and proximate analysis was carried out to determine the ash content, volatile matter, and moisture content. Permeability and porosity of the coal was obtained to determine the gas content and flow characteristic of gas through the coal bed. Reserve and recoverable gas from the coal bed methane field under study was estimated from the adsorption-desorption experiments and simulation study. Future production rate of gas and water and dewatering time were predicted using Fekete coal bed methane software.
