Coalbed methane is the methane rich gas found naturally within coal seams. Such methane is held in place on the coal surface as a free or sorbed gas by the pressure of the surrounding rock and pore water. By controlling the release of this pressure, the methane can be harvested and burned for electricity generation or pumped to the national grid. The present study examines the economic potential of utilising coalbed methane from virgin coal seams at a study area in South Wales and selling that to a power station for electricity generation. The model takes into account several parameters the most important of which are the methane content of the coal, the permeability of the coal, the drainage area of the boreholes, the CAPEX and the OPEX. A decline curve analysis using the exponential decline technique for estimating the future gas production of the study area and the UK Navigant gas projection prices are used to estimate the economic potential of the operation. The results show that methane recovery from virgin coal seams can be considered as an economic option for power generation for the selected study area.
