Coalbed Methane
The maceral composition of coals may impact the ability of coal to generate and/or store natural gases, primarily methane. The USGS is actively pursuing studies to elucidate the role of maceral content on gas generation and storage, primarily in the Gulf Coast region of the United States. Coal samples from coalbed methane test wells are desorbed to measure actual stored gas content, microscopically analyzed for organic content, and subjected to adsorption isotherm analyses to measure the coal’s ability to store gas. These comparative studies allow predictions of the role of maceral content on gas storage and may help in understanding gas generation.
