A semi-analytical model for gas–water two-phase flow in deep shale gas formation considering partially-propped hydraulic fractures with stress-dependent conductivities

Key Points

• Gas-water flow behavior is significantly influenced by hydraulic fractures in deep shale gas systems.
• The semi-analytical model effectively captures stress-dependent conductivities, impacting flow dynamics.
• Assessment using a semi-analytical framework provides insights into two-phase flow in complex geological settings.
• Highlights the importance of considering hydraulic fractures for optimizing gas extraction strategies.
