Field evidence shows that fractured porous media are comprised of randomly distributed natural and/or hydraulic fractures. Those complex fractures are of great importance to the management of water production, carbon sequestration, and petroleum resources.

In recent years, various methods have been tested experimentally and in theory to explore their potential in understanding the flow and transport dynamics in fractured porous media. For example, pressure/rate transient analysis (PTA/RTA) is a good approach to identify the flow regimes in fractured porous media based on the wellbore pressure/rate. However, mathematical models cannot efficiently consider all the important details, such as multi-phase flow, a number of fractures in the thousands, and randomly distributed fracture networks. In addition, due to the complexity and arbitrary nature of fracture geometry, it is still a challenge to study flow and transport dynamics in fractured porous media.

The Special Issue aims to gather recent studies on flow and transport dynamics in fractured porous media. It aims to bring together experimental and field observations with theory and numerical simulations to advance our understanding of flow and transport dynamics in fractured porous media with complex fractures.

Potential topics include but are not limited to the following:

• New concepts, theories, methods, experiments, and techniques in fractured porous media
• New experiments and modelling to characterise fractured porous media
• Pressure/rate transient behaviours in fractured porous media
• Advanced analytical methods and modelling for fractured porous media
