"Following cased hole geophysical logging operations, Carolina #1 has intercepted a total of 21m of pay zone (coal and carbonaceous shale) at a depth interval ranging between 830 and 990m. Net coal thickness has been estimated 17m in this pay zone according to 1.75 gr/cm3 density cut-off."

qq, in my untrained opinion there are many factors that determine the CSG economics of a coal seam/s. The 'net coal' figure is a description of how much gas bearing coal they believe they intersected. The seams vary in size, but cumulatively are added up to obtain a 'net; figure as the vertical well intersects all the seams down to a drilled depth. Depending on the 'gas content' of the coal and lateral extent of the coal seams, you can then make a determination of how much actual gas is in place. You can see the actual coal seams on the technical presentation (slide 18 ---- http://www.blueenergy.com.au/_dbase_upl/CSG%20and%20CMM%20Conference%20Presentation.pdf).

The exctracability of this gas is then driven by how permeable (think sponge like) the coal is which I believe is determined by many things such as how the coal was formed and changed with pressures, as well as what depth and pressure the coal is currently under. Other infrastructure considerations at the surface then also apply, such as access to market (pipeline).

Not advice, just my unqualified opinion.
