coal bed methane - Schlumberger Oilfield Glossary

Natural gas, predominantly methane [CH 4 ], generated during coal formation and adsorbed in coal. Natural gas adsorbs to the surfaces of matrix pores within the coal and natural fractures, or cleats, as reservoir pressure increases.

Stimulation Techniques of Coalbed Methane .Traduire cette page

Coalbed methane (CBM) plays an important role in securing world energy supply and transiting electricity generation from fossil fuel to renewables. CBM reservoirs are generally very tight and require effective stimulation to achieve economic extraction. In recent years, an increasing number of coal seam stimulation techniques were developed, but selecting the most suitable stimulation ...

China produced 17.1 billion cubic meters (BCM) of methane sourced from coal seams in 2015, of which 4.43 BCM is from wells drilled from the surface. This level of production is a clear indicator that China has gone into early stage large-scale coalbed methane (CBM) development. CBM resources in China have been extensively investigated since the 1980s. Research has focused on the geological ...

Black Warrior Riverkeeper - Coalbed Methane & .

The first drilling for coalbed methane – aka natural gas – in Alabama occurred in the Black Warrior Basin in the 1970s. Initially, this practice served as a way to degasify coal seams prior to mining them, to attempt reducing the potential for explosions in mines. The gas was simply vented into the atmosphere. In the early 1980s, when it was realized natural gas has tremendous energy ...

Methane from Coal. The natural gas methane is a byproduct of coalification -- the process where plant materials were gradually buried, compressed, and heated, resulting in the various ranks of coal. In Pennsylvania, natural gas is extracted from coal as coalbed methane and as coal mine methane. Coalbed methane comes from (unmined) coal ...

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.

Coal bed methane - Energy Education

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.

13% of the land in the lower 48 United States has some sort of coal under it, and nearly all of this coal contains methane. Methane gas, a hazard in underground coal mining, is normally wasted into the atmosphere. A process developed during the search for non-conventional fuels permits the extraction of this natural gas from the coal beds. Coalbed methane is produced in 7 counties in Alabama ...

Coalbed methane - WikiMili, The Free Encyclopedia

Coalbed methane is distinct from a typical sandstone or other conventional gas reservoir, as the methane is stored within the coal by a process called adsorption. The methane is in a near-liquid state, lining the inside of pores within the coal (called the matrix). The open fractures in the coal (called the cleats) can also contain free gas or can be saturated with water.
