Understanding the controls on coal seam distribution and geometry is fundamental for planning coal seam gas production. In the Jurassic Surat Basin of South East Queensland, Australia, the spatial continuity of coal seams in the Walloon Coal Measures is highly variable and often difficult to map and predict, even with closely …

Australia has relatively large supplies of coal seam gas (CSG) resources, especially in Queensland and New South Wales. CSG has been produced in Queensland from the Bowen Basin since 1997 and in the Surat Basin since 2005. Exploration has occurred in other Queensland basins, New South Wales, and other parts of Australia where there are

With the first phase of the …

The coal seam gas (CSG) industry is expanding rapidly in the Surat and Bowen Basins of Queensland. CSG production involves pumping water from the coal seams to release the gas adsorbed to coal particles. The reduction in water pressure in the coal seams will cause some reductions in water pressure in overlying and underlying aquifers because …

To produce coal seam gas (CSG), wells are drilled into underground coal seams, bringing water (CSG water) from the seams to the surface. This process reduces pressure in the seams which allows CSG to be released. The quality of CSG water quality varies greatly, however it is generally rich in salts and other minerals.

Solid production in coal seam gas (CSG) wells has posed significant financial and technical challenges to operators working on Walloon Subgroup, Surat basin, Queensland, Australia (Ge et al., 2018).

This study used compositional and stable isotopic analysis to test hypotheses on the distribution and origins of Walloon Subgroup coal seam gas (CSG) in the eastern Surat Basin, Queensland, Australia. The Middle Jurassic Walloon Subgroup play differs from many other low-rank CSG plays—particularly in methane carbon isotopic signature, …

Cumulative management area. Under the Water Act 2000 (Water Act), a cumulative management area (CMA) can be declared if an area contains two or more resource tenures, including tenures on which coal seam gas (CSG) and mining activities operate, and where there may be cumulative impacts on groundwater resulting from …
