This is an indepth article and worth a read. You can see Molopo's share in the pie graph.Bit to long to post here and the charts will probably not paste knowing my luck and expertise.Lots about Gladstone.
Heres the first couple of paragraphs for a taste.
Dubbed "girlie gas" by skeptics in the early 1990s, Australia's coal seam gas (CSG) sector has risen in the space of 2 decades to be one of the country's major energy resources, particularly in the eastern states. The numbers are huge. The estimated potential in situ CSG unconventional resource contained in eastern Australia is on the order of 418,000 petajoules or 400 tcf (where 1 petajoule is equivalent to 0.957 bcf). This resource lies primarily in the Surat, Bowen, and Galilee basins of Queensland and the Sydney, Gunnedah, and Clarence-Moreton basins of northern New South Wales.
