Coalbed methane resources and reservoir characteristics from the Alberta Plains, Canada

Coal mine methane: A review of capture and utilization practices with benefits to mining safety and to greenhouse gas reduction

“…A special form of parting is composed of altered volcanic ash layers (tornstein) which represent volcanic events of short duration and therefore are nearly isochronous horizons, such as in the Ferron group in Utah, which may also be found within coal seams (Lamarre, 2003). Rock partings or parting layers create density variations in the coal, which are a function of mineral material, or ash, within the coal seam (Beaton et al, 2006;Manchioni, 2003). Most importantly in relation to fluid and gas flow, these partings create strong discontinuities in the petrophysical fabric (porosity and permeability) within the coalbed methane reservoir.…”

Produced fluids and shallow groundwater in coalbed methane (CBM) producing regions of Alberta, Canada: Trace element and rare earth element geochemistry

“…The production of natural gas from coal (NGC) or coalbed methane (CBM) from shallow coals is a relatively new industry in Alberta (Canada) and represents a vital new source of natural gas supply in North America Beaton, 2002;Beaton et al, 2006). Coalbed methane exploration in the province of Alberta has rapidly increased since 2000.…”

Life cycle assessment of hydrogen production from underground coal gasification

“…Furthermore, CO 2 sequestration can be combined with UCG, mainly because of the close proximity of CO 2 sequestration sites with the un-mineable coal reserves [17][18][19]. Therefore, keeping in mind the abundant coal reserves in Alberta, http which are estimated to be in the range of 2-3 trillion tons, 1 UCG along with carbon capture and sequestration (CCS) can potentially be an environmentally benign H 2 production pathway [20][21][22][23]. More recently, the feasibility and the operation of UCG for syngas production in Alberta was successfully demonstrated by Swan Hills Synfuels LP [24].…”
