Coal Bed Methane (CBM) is an emerging energy resource in Australia, which has multi-billion dollar CBM reserves. Gas is clean burning, produces little greenhouse gas and almost no disruption to surface activities (like farming) during extraction. These environmental benefits, with low cost, make gas the fuel of choice for power and heat worldwide. This project seeks to assist development of CBM engineering from deep coal seams. These contain the most gas, but are technically more difficult to develop than shallower reservoirs. In particular, it examines how natural and induced stress fields can be used to improve productivity, by understanding the relationships between different coal types, their environment and gas production rate.

煤层气是澳大利亚的一种新兴能源，拥有数十亿美元的煤层气储量。天然气是清洁燃烧的，几乎不会产生温室气体，在开采过程中几乎不会破坏地表活动(如农业)。这些环境效益和低成本使天然气成为全球电力和热能的首选燃料。该项目旨在辅助深部煤层煤层气工程的发展。这些气藏含有最多的天然气，但从技术上讲，比起较浅的油气藏更难开发。特别是，它研究了如何通过了解不同煤炭类型、环境和产气率之间的关系，利用自然应力场和诱导应力场来提高生产率。
