Modelling the dynamic and anisotropic permeability of coal under CO2 geo-sequestration conditions (2011–2013)

Abstract:
This project addresses the gas transport in coal under dynamically changing geomechanical conditions, a bottleneck scientific issue for coalbed methane recovery from or carbon dioxide sequestration into coal. It will provide a new permeability model for enhancement of existing reservoir simulation by incorporating direction dependent behaviour, which is particularly important for gas production and storage. Such a model does not currently exist for coal. The objective is achievable by combining multiphysics simulation techniques with experimental information on coal fabric and its pore structure resulting from x-ray computer tomography technology, and the gas-sorption-induced coal deformability monitoring through direct measurement.
