| Coal Bed Methane (CBM) |
||||||
| is a natural gas containing |
||||||
| virtually 100% methane |
||||||
| (CH4) produced from coal |
||||||
| seam
reservoirs. |

|

|
|
| CBM
is often produced at |
||||||
| shallow depths and is often |
||||||
| produced with large volumes |
||||||
| of water of variable quality. |

|
|
| CBM is an increasingly important part of the Nation’s |
||||||
| energy
portfolio; it can be produced in an |
||||||
| environmentally protective manner but it presents |
||||||
| unique challenges for owner/operators and regulators. |
