What is coal bed methane?
Coal bed methane is natural gas that occurs in coal beds and has been generated during the conversion of plant material to coal (the process known as coalification).
Coal bed methane is produced from a broad range of coal from low rank subbituminous coal through to high rank bituminous coal.
What are the key ingredients for CBM production?
Known, thick, abundant and laterally continuous coal beds
Coal-bearing areas with coals of appropriate rank
Indications of favourable reservoir for accumulation and preservation of coal bed methane
Relatively shallow deposits ~ less than 1,000m
Evidence of fracturing and faulting in coal, correct geothermal gradient
The presence of gas fields producing from coal-bearing rocks

| CBM drilling |
Brightway CBM drilling mud recycling system is normally with the capacity as 350 GPM and 500 GPM.
The main relative equipment are shale shaker, mud cleaner, centrifuge,mud gas separator, tank, etc.
