The Alberta Energy Regulator estimates 91 billion tonnes of coal resources exist at a depth suitable for mining. An additional 2 trillion tonnes of coal at depth exist in the Alberta Plains that may be suitable for coalbed methane (CBM) exploration. Coal in the Alberta Foothills and Alberta Mountains would also significantly add to this tonnage. In total, it is estimated that 14 trillion cubic metres (500 tcf) of gas in place exist in all of the coal in Alberta.
The Alberta Plains contains seven major coal zones:
Our report on the regional evaluation of the coalbed methane potential of the foothills/mountains of Alberta describes the geology and CBM potential of the foothills and mountains of Alberta.
Two of our reports (Coalbed Methane Potential of Upper Cretaceous-Tertiary Strata, Alberta Plains and Production Potential of Coalbed Methane Resources in Alberta) describe the geology, chemistry and CBM potential of the major coal zones in the Alberta plains.
The below diagrams are from the above reports and a large coal database. They show the general coal distribution, net coal thickness and CBM potential for each major coal zone in the Alberta plains.
