Coalbed Methane
Coalbed methane has become a
major source of natural gas in the United States. This resource is truly an
unconventional source of gas. In conventional reservoirs gas is stored by
either compression or solution. Coalbed methane is stored by the physical
process of adsorption. Further, most conventional reservoirs require the
migration of hydrocarbon fluids to a trap. Coalbed methane is generated in
place during the coalification process. These two features make coalbed methane
different to explore and develop.
Fairchild and Wells, Inc. has
been a pioneer in the understanding and prediction of coalbed methane reserves.
The coupling of the adsorbed gas in the coal with the flow in the natural
fracture system, yields unusual production characteristics such as increasing
gas flow with time, declining water ratios with time, and high sensitivity to
well spacing. All these features make coalbed methane evaluation very complex.
By understanding the process, FAW has become a leader in the evaluation and
prediction of coalbed methane reserves.
FAW experience has included
projects in all the major basins in the United States such as Black Warrior Basin
of Alabama, San Juan Basin of New Mexico and the Appalachian Basin of
Pennsylvania, West Virginia, and Virginia. Experience also includes several
other Rocky Mountain Basins, Eastern Europe, and Australia. These projects have
resulted in several technical papers and many presentations.
