Research into subsurface characterisation of sandstone and carbonate reservoirs is well developed, along with the methods of modelling fluid storage and transport within them. However some of these methods do not accurately represent the processes within Shale reservoirs.This doctoral research project aims to focus on creating an analytical model for gas flow through a shale reservoir. In Part A of the project, we aim to complete a technically rigorous model for flow through the porous matrix and planar fractures. Part B of the project aims to develop realistic functions for stress dependant permeability and transmissivity, then implement these in the model. In Part C, we aim to incorporate the flow model developed in parts A and B into a geomechanical fracture model. Specifically the multi-institutional numerical framework CSMP++.

砂岩和碳酸盐岩储层的地下特征研究以及模拟它们内部流体储存和运输的方法都很发达。然而，这些方法中的一些并不能准确地表示页岩油藏内的过程。这个博士研究项目的目标是创建一个页岩油藏天然气流动的分析模型。在该项目的A部分中，我们的目标是完成一个技术严谨的渗流模型，该模型用于渗流基质和平面裂缝。该项目的B部分旨在开发与应力相关的渗透率和透过率的现实函数，然后在模型中实施这些函数。在C部分中，我们的目标是将A部分和B部分中开发的流动模型融入到地质力学裂缝模型中。具体地说，多机构数值框架CSMP++。
