The Cooper basin is well known and is close the core of the development of domestic gas supply in Australia.

From 1970 to 2010, something like 5200 PJ of gas has been sold ... thats an average of 130 PJ per year. In the 12 months to 2010 something like 74 PJ was sold so it is clear the Cooper basin is in decline.

Your point that the they could monetise the gas with sales of 20 PJ and then sit tight till the reserves were more critically valued by others is a good one imo .. even if slightly more per year was required to justify pipeline and extraction scale.
