Hydraulic fracturing (fraccing) is a technique used to enhance gas flow from CSG wells in areas where the coal seams have low permeability. It involves injecting a mix of water and sand (typically 99%) and 1%industrial chemicals into the coal seam under high pressure in order to create small fractures that allow the gas to flow more readily to the well. Media attention has focused on the potential impacts of fraccing and many community members have expressed concern that valuable...

CSG companies and the Queensland Government collect data about the volumes of various types of groundwater use. This data helps estimate groundwater extraction volumes used in groundwater models which inform decisions regarding the management of the industry and plan water allocations. For example, the Queensland Government model is used to identify which private water bores are likely to have declining groundwater levels as a result of CSG industry activities and compensation for water loss is negotiated between the companies and...

The amount of water (flux) entering an aquifer as recharge is a critical factor in determining how water table levels change, the sustainable yields for groundwater extraction, and the impact of extractive industries on groundwater availability. However, the processes that govern this flux remain difficult to quantify, and are therefore considerable sources of uncertainty in modelling the groundwater balance and conducting impact assessments. Due to the geological complexity of the Surat and Bowen Basins, recharge can occur via multiple pathways...

There continues to be a significant level of community concern regarding the potential environmental impacts of the developing CSG industry in Australia. While large-scale CSG development is a recent phenomenon in Australia, the industry has a long term history in both Canada and the USA (where CSG is known as coal bed methane or CBM). This project will review the literature on the environmental impact of coal seam gas development in Australia, Canada and the USA. The US CBM industry...

The Australian Government is undertaking a programme of bioregional assessments in order to better understand the potential impacts of coal seam gas and large coal mining developments on water resources and water-related assets. The science-based studies follow a methodology to develop multi-layered records of the natural environment in specific bioregions. The studies will analyse the ecology, hydrology, geology and hydrogeology of bioregions, with explicit assessment of potential direct, indirect and cumulative impacts on water resources both above and below ground...

The CSG industry uses a range of technologies to monitor factors such as gas production, pressure and water quality. One method is by drilling monitoring wells that are costly, require land access and maintenance, and only provide information at one location. This research is seeking to identify monitoring technologies that are more cost effective, provide more geographic coverage and are also less disruptive for landholders. During 2014 the research team used modelling techniques to evaluate several different non-seismic geophysical techniques...

A technical feasibility study was completed to determine if there is sufficient groundwater quality data available to develop a Water Chemistry Atlas with the capability to address key technical questions regarding regional water quality trends and provide valuable information to government, industry and the community. Key steps included: Developing a test database structure for the Atlas and use of a subset of data from the Office of Groundwater Impact Assessment (OGIA) water quality database for trial purposes. using a range...

This paper overviews the storage and treatment processes used by the Sydney Catchment Authority and Sydney Water to provide drinking water for the 4.5 million citizens of Sydney. At the moment the treated water from Sydney Water comfortably meets Australian Drinking Water Health Guidelines. Fears have been expressed that if activities like long-wall coal mines and coal seam gas recovery proliferate within Special Areas and in catchments, surface water could become contaminated and pose a difficulty in ultimate water treatment...

On 6 November 2013, Deakin University's School of Law presented the first-ever conference at The Sofitel Hotel examining the future of Coal Seam Gas and Unconventional Gas Regulation in Victoria. Around 85 participants attended the Melbourne event, which included a series of discussion papers, presentations and a panel debate on the emergent regulatory issues relevant to coal seam gas and unconventional gas mining. It was a rigorous and thoughtful debate that opened the conversation around issues such as: Comparative regulatory...

This paper discusses the main causes of subsidence with particular emphasis on the effects associated with CSG extraction, including: The most common subsidence problems occurring in different engineering scenarios, and discusses: The main characteristics of the coal seam gas extraction, including the most common methods employed for gas extraction, the main mechanisms of subsidence related to CSG extraction, and their potential impacts. The influence of the different extraction configurations, their similarities compared to other mining activities, the potential ‘worst’ case...
