In coal seam gas (CSG) reservoirs, the hydraulic conductivity of the connected pore space is governed by two-phase flow patterns under the combined influence of microstructure and interfacial tension. The conventional knowledge and techniques for dual phase/multiphase flow modelling carried out at the macro scale have significant limitations in CSG flow analysis and can yield variable results for CSG process design and production. Jie Yi's PhD project aims to improve our understanding of coal gas-water two-phase flow dynamic behaviour in complex coal seams at the micro-pore scale to improve the efficiency of CSG exploitation through predictable numerical simulations on advanced supercomputers.
