Quantification of Multiphysics phenomena of Gas flow in organic rich shales

我们讨论了从页岩等名义上不透水的岩石中提取天然气的性质这一科学问题。我们的主要目标是开发一个完全耦合的微结构富集型热力学连续介质模型来预测页岩油藏在天然气生产过程中的多物理行为，并通过在三个澳大利亚盆地(包括Cooper、Perth和Beetaloo)的地层上进行具有代表性的实验来验证该模型，这些盆地的样品可供研究人员使用。我们采用理论-数值-实验相结合的研究方法来解决这个问题。这是国际上首次尝试开发这种经过实验验证的基于热力学的模型，特别是针对澳大利亚的页岩。

We address the scientific question of the nature of gas extraction from nominally impermeable rocks such as shales. Our main aim is to develop a fully coupled microstructurally enriched thermodynamic continuum model to predict the Multiphysics behaviour of shale reservoirs during gas production and verify the model with representative experiments conducted on formations from three Australian Basins including Cooper, Perth and Beetaloo, where the samples are available to the investigators. We approach this problem in a hybrid theoretical-numerical-experimental study. This is the first international attempt to develop such experimentally verified thermodynamic based model, particularly for Australian shales.
