Mudstones as methane sources: gas production from coal seam interburden

与已被开采为天然气的煤系有关的碳质泥岩是一个有吸引力的甲烷储层。该项目旨在提供获取这种气体的方法。与煤层气开发有关的泥岩非常广泛，其天然气量甚至可能超过煤本身。进一步的基础设施和准入许可证已经到位，用于煤层气回收。与易裂变的页岩不同，泥岩更软，更具延展性和塑性，因此会对水力压裂和支撑产生异常反应，因此本项目需要开发新的增产方法。

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.
