ECLIPSE Coalbed Methane (CBM)

Optimize your CBM development

The naturally occurring methane within coal seams can in some cases be economically produced using oilfield technology. In these coalbed methane projects, wells are drilled into the coal seam to produce gas. Considerable reserves of this unconventional natural gas are present in many parts of the world.

The coal beds are naturally fractured systems with the gas adsorbed into the coal matrix. Primary production occurs by initially dewatering the natural fractures, and thus reducing the pressure in the fracture system. The reduced pressure in the fractures allows gas desorption from the surface of the coal to the fracture. Gas diffuses from the bulk of the coal towards the fracture surface.

For dual porosity, the Coalbed Methane option uses a modified Warren and Root model to describe the physical processes involved in a typical coalbed methane project.
