Coal Bed Methane

What is CBM?

Coal Bed Methane (CBM) is a methane gas (CH4) occurring naturally in coal seams.  It is also called as Coal Seam Methane (CSM) or Coal Seam Gas (CSG). Coal Bed Methane is now recognized as a valuable energy resources, rather than just a challenge for underground coal mining.

Our Role in CBM Development

The CBM Services Division is supported by our Exploration, Geological & Laboratory Services, Environmental, Coal, and Occupational Safety & Health Divisions. Our Coal Laboratory Services Division, with their network of well equipped laboratories across Indonesia, is ISO-17025 accredited.

CBM in Indonesia

Indonesia has extensive coal resources, which have been estimated to hold up to 453 trillion cubic feet of Coal Bed Methane. These reserves are mainly located in Kalimantan and Sumatera.

The Indonesian government is considering implementation of special incentives for companies who develop Coal Bed Methane.

In addition to our own facilities and expertise, the company has various affiliations with internationally recognize companies and specialist consultants who can provide additional expertise in analyses, interpretation, and project planning and development.
