This project aims to deliver a better model for coal relative permeability to improve the management of coal seam gas reservoirs. Coal relative permeability is a key factor in reservoir models; however, current understanding of relative permeability is wrong for coal systems and predictions based on it are misleading. Relative permeability is currently carried over from conventional gas reservoirs as a function of the degree of water saturation only. This misunderstands the physical differences between coal and other rocks as gas reservoirs, fails to recognise the determinants of coal relative permeability, and misrepresents the flow system. This project seeks to provide a phenomenologically-based understanding and functional relationship for coal-relative permeability based on the principles than govern physical flow interactions.

该项目旨在提供一个更好的煤相对渗透率模型，以提高煤层气藏的管理。煤的相对渗透率是储层模型中的一个关键因素，然而，目前对煤系统相对渗透率的理解是错误的，基于它的预测是误导的。相对渗透率目前仅作为水饱和度的函数从常规气藏传递过来。这种观点忽视了煤与其他岩石作为气藏的物理差异，没有认识到煤的相对渗透率的决定因素，并且错误地描述了流动系统。该项目旨在提供一个基于现象学的理解和功能的关系，煤的相对渗透率的基础上的原则，而不是管理物理流动的相互作用。
