Fully Coupled Adsorption-Hydro-Mechanical Model for Wellbore Stability Analysis in Non-Saturated Shale Gas Reservoirs Using Dual-Pore Dual-Permeability Model

Key Points

• Wellbore stability improves with dual-pore modeling, crucial for safe extraction in shale gas reservoirs.
• Key metrics show significant reductions in stability risks, particularly under non-saturated conditions.
• Analysis of coupled adsorption and hydro-mechanical interactions highlights their importance in wellbore safety.
• Enhanced modeling approaches may enable better predictions, necessitating further validation under diverse field conditions.
