Coal seam gas (CSG) is produced by extracting water from coal seams to release the pressure that holds the gas in place. This results in water coming to the surface. The water is known as ‘produced water’, ‘associated water’ or ‘CSG water’. A major challenge in managing CSG water is predicting how much water will be produced, and when and where, as the industry develops. The (then) Queensland Department of Environment and Resource Management (DERM) commissioned Klohn Crippen Berger Ltd (KCB) to develop a tool to forecast where, when and how much CSG water will be produced in the Surat and southern Bowen basins. This report describes how the tool was developed, how the tool works and the produced water estimates based on three industry-expansion scenarios for the period 2010–2060.
