Anisotropic behaviour of coal for coalbed methane recovery and CO2 geosequestration

Abstract:: Coalbed methane is recognised as a major source of clean energy supply in Australia. New reservoir models that underpin predictable, sustainable and economic recovery of coalbed methane, or injection of carbon dioxide into coal for geosequestration and enhanced coalbed methane recovery, require as input data information on the directional and dynamic response of coal to gas removal or addition. This data does not currently exist. The project develops new methods to measure, interpret and report the directional interaction of mechanical stress, gas sorption and strain on the coal fabric and its pore structure, on bulk coal as a composite material, and on the cleats and fractures that govern the fluid flow in it.
