Coalbed methane gas is extracted by a process called degasification, which is required to prevent explosions during the coal mining process. Until recently, coalbed methane gas was not commercially marketable. As such, it was not expressly referenced in the chain of title in Kennedy v. Consol Energy Inc., 116 A.3d 626 (Pa. Super. Ct. 2015).

Fractures, or cleats, within coal beds are usually filled with water. Deeper coal beds contain less water, but that water is more saline. Removing water from the coal bed reduces pressure and releases methane. Large amounts of water, sometimes saline brine, are produced from coalbed methane wells.

Methane was produced from a few coal seam wells in Wyoming, Kansas, and West ia during the early part of the twentieth century; however, the first deliberate attempts to complete wells as coalbed-methane (CBM) producers did not occur until the early 1950s in the San Juan basin of New Mexico.

Coal bed methane is methane trapped in underground coal seams.This type of methane can be accessed using drilling techniques similar to those used in the collection of shale gas.In these deposits, the methane is attached to the surface of the coal.Generally, the seams are also covered in water which must be pumped out to obtain the methane.

Coalbed methane (CBM) is a form of natural gas that occurs in coal beds. During the coalification process, large amounts of gas (mainly methane) are formed biologically in the coal deposits and released during coal extraction. Although CBM production is a complementary aspect of coal mining, it has only started to gain attention in recent years.
