Coal bed methane for the future of gas reserves in Indonesia is one topic explained in BUMI Bulletin published by SKK Migas (Indonesia Special Task Force for Oil and Gas). This topic is very interesting because I never considered coal bed methane (CBM) as source of gas until now. CBM is hydrocarbon formed and kept in source rock, it does not move or migrate. In Indonesia, CBM reservoir is very wide and its resource and reserve is large.
