The Coalbed Methane (CBM) in the Northern Bowen Basin, Australia was explored by MGC Resources Australia Pty. Ltd. (MGCRA) from 1990 to 1995 in order to confirm the volume and cost of CBM as a raw material sufficient for the methanol production plant. Unfortunately this project did not get promising results. The failure causes are attributed to the unexpected low permiabilities, heterogeneous permiability distributions, existence of secondary minerals in the coal cleats or fractures and of undersaturated gas adsorption zones. To overcome these problems and to improve the CBM productivity, some R & D ideas are discussed in this paper regarding the exploration methods, permeability improvement, well completions and others.
