Coalbed methane (cbm) energy resources in Australia exceed $20b in value. One of the production issues with recovering cbm is fines that are created or exist in the coal, which block gas flow to the recovery wells and damage downstream equipment. Understanding how fines are created and migrate within gas wells and then overcoming this problem, the purpose of this research, could deliver additional gas production worth over $1.8billion and reduce maintenance costs related to cbm extraction by $25m per year.

澳大利亚煤层气（cbm）能源资源的价值超过200亿美元。开采煤层气的生产问题之一是煤中产生或存在的细颗粒，这些细颗粒会阻碍天然气流向采出井，并损坏下游设备。这项研究的目的是了解颗粒在气井中是如何形成和迁移的，然后克服这一问题，这可能会带来超过18亿美元的额外天然气产量，并将每年与煤层气开采相关的维护成本降低2500万美元。
