We made a study on the influence of presumable CBM (Coalbed methane) commercial production on the natural gas trades in Asia. Some possible scenario cases and a special scenario case assuming LNG trade between China and Indonesia were calculated. First, the supply rates of various natural gases were calculated so that the sum of total supply cost in an importing country would become the lowest. And next, similar calculations ware carried out so that the sum of total supply cost of an importing country and the production cost of an exporting country would become the lowest respectively. The following results were obtained by these calculations.
(1) The climb rate of production cost of a conventional natural gas can be controlled by the alternative energy source CBM.
(2) The above influence of CBM production becomes apparent by considering the profits of both countries.
(3) CBM should play an significant role to satisfy ever increasing natural gas demand in the next 30 years in Asia.
