Formatted Abstract/Summary
Coal bed methane (CBM) fields in sedimentary basins are possible repositories for anthropogenic CO2, with the added economic benefit of enhanced recovery of CBM. CO2 is stored in coal as adsorbed molecules on micropore surfaces, but will also dissolve in formation water (solution trapping) and react with Ca, Mg and Fe-bearing minerals in the coal. Dissolution and precipitation reactions will buffer the pH decrease associated with injection of CO2 and may result in the formation of carbonates (mineral trapping). In the current study we have investigated mineral paragenesis and the physico-chemical conditions under which diagenesis occurred in CO2-rich and CO2-poor coal seams and adjacent strata of the Gunnedah and Bowen Basins.
