METHOD FOR PERMEABILITY PREDICTION OF SHALE GAS

摘要

This disclosure relates to a system and method for applying a prediction of permeability of shale gas in porous media at different pressure conditions to a shale gas production. The method uses a molecular model that accounts for slippage and adsorption effects under the different pressure conditions including simulated gas flows in a large computational domain representing a sample of shale rock. This system and method provides a computationally efficient processing to determine permeability variations of shale gas with the different pressure conditions.
