Coal Seam Gas
Metgasco has focused its coal seam gas evaluation efforts on the Walloon Coal Measures ("WCM"). These coal measures are extensive throughout the Surat basin (Queensland). The Clarence Moreton basin, in New South Wales, represents the southern extension of these coals.
The WCM have become major coal seam gas producers in Queensland with these coals now providing over 60% of the State's gas supplies. In the Clarence Moreton basin, the WCM consist of a sequence of fluvial, lithic-rich sandstones, interbedded with shales, carbonaceous shales and coals.
The WCM occur at a depth of between 200 m to 800 m, have high gas content, tend to be oversaturated with gas and have good seam thickness of between 2 - 9 metres. The Company has identified 11 coal seams within PEL 16. Gas composition analysis shows a very pure form of natural gas with approximately 98% methane (CH4) content or over and negligible carbon dioxide (CO2)
Conventional Hydrocarbons
The Clarence Moreton basin is one of the most underexplored petroleum basins in Australia. Metgasco considers that, in addition to the vast coal seam gas resources that it contains, that it is prospective for conventional hydrocarbon discoveries. Conventional hydrocarbons are considered to be hydrocarbon resources trapped in a sandstone reservoir by structural or stratigraphic traps.
