19 Mining and the Lake Eyre Basin environment 185 gas from the Cooper–Eromanga Basin in South Australia and Queensland peaked in 2002, leading to a significant increase in production of unconventional gas from CSG fields (Fig. 19.9). This explains why the Queensland Government has increasingly supported CSG as a major gas supply (Queensland Department of Natural Resources and Mines 2015), rather 0 100 200 300 400 500 1964 1974 1984 1994 2004 2014 Gas production (PJ/y ear ) 0 9000 18 000 27 000 36 000 45 000 2005 2007 2009 2011 2013 Gas reserves (PJ) (a) (b) Fig. 19.9.
