An investigation of carbon sequestration/ECBM potential in Australian coals: a simulation study for Sydney Coal Basin.

Shrivastava, Rahul January 2006 (has links)
Title page, abstract and table of contents only. The complete thesis in print form is available from the University of Adelaide Library. / A 2002 report by Australian National Greenhouse Gas Inventory suggests that since 1990 Australia's net emissions of carbon dioxide equivalent from stationary combustion sources are on the rise and they are likely to rise even at a higher rate in keeping with continued economic and industrial growth. In order to reduce Australian CO₂emissions, there is a need to identify and explore large-capacity storage locations for CO₂ sequestration. In that context, Australian coal seams, notably the coal-bed methane (CBM) reservoirs in Sydney and Bowen Basins, could potentially be attractive sites to sequester large volumes of greenhouse CO₂ emissions while also recovering the methane gas, a relatively cleaner source of fossil fuel. This study investigates the deliverability and economic feasibility of CO₂ sequestration through CO₂-Enhanced CBM recovery (CO₂-ECBMR) in the Camden area, Sydney coal basin. The results of the study show that the CO₂-ECBMR impacts the absolute pelmeability of the Camden area significantly. Because of a good reticulated fracture system, the CO₂ breakthrough from the producers is faster. The enhancement of CH₄ recovery by preferential adsorption of CO₂ occurs simultaneously with the abatement of CH₄ recovery by overall decrease in permeability in the CBM reservoir. Hence, the actual CH₄ is produced under the overall effect of these two competing processes, with the operating parameters like producer-injector spacing and injection pressure affecting their relative dominance over each other. The study also addresses the opportunities of a niche for CO₂ sequestration in these coals, which will be dictated mainly by the factors of sequestration economics and status of these coals being "unmineable". The results derived from the study could help the design of an optimum operating strategy in implementing the CO₂ sequestration and enhanced CBM recovery in Sydney Basin, Australia and elsewhere. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1259968 / Thesis (Ph.D.) -- University of Adelaide, Australian School of Petroleum, 2006
