Carbonaceous mudstones associated with coal measures already exploited for gas present an attractive reservoir of methane. This project seeks to provide methods for accessing this gas. Mudstone associated with coal seam gas developments are very extensive and gas quantities may exceed even that in the coal itself. Further infrastructure and access permits are already in place for coal seam gas recovery. Unlike shale, which is fissile, mudstone is much softer, more malleable and plastic, and consequently will respond abnormally to hydraulic fracturing and propping, so new methods proposed to be developed in this project are needed for stimulation.

与已开采天然气的煤系相联系的碳质泥岩是一个有吸引力的甲烷储集层。该项目旨在提供获取这种天然气的方法。与煤层气发育有关的泥岩非常广泛，其含气量甚至可能超过煤本身的含气量。煤层气开采的进一步基础设施和准入许可已经到位。与易裂变的页岩不同，泥岩更柔软，更具延展性和可塑性，因此会对水力压裂和支撑产生异常反应，因此需要在该项目中提出新的增产方法。
