Methodologies for Investigating Gas in Water Bores and Links to Coal Seam Gas Development

Sep 2014. Methane in water bores is a major concern in areas of coal seam gas (CSG) development. There are risks associated with ignition and asphyxiation in closed spaces around bores that create real concern. There are also other risks, such as gas lock in pumps, colour and odour impacts from water quality changes, toxicity due to other gases and build up of gases affecting the integrity of the bores.

To address these risks, there is a need for an appropriate monitoring, management and response strategy, commensurate with the risks.

Responsibilities for these strategies are variably divided between the industry, government and private concerns. This report deals with the state of the art of methods for investigating gas in water bores and analysis of resulting data world‐wide and historical presence of gas in
water bores in the Surat and Bowen basins. Information from this report is to be used to investigate and respond to reports of increased gas content in individual water bores across a large area in Queensland.

For such work to be effective, a good understanding of the processes for and limitations of measuring gas in water bores is critical.
