A Numerical Study of Thermal-Hydraulic-Mechanical (THM) Simulation with the Application of Thermal Recovery in Fractured Shale Gas Reservoirs

Abstract

We presented a general multi-physics model for shale gas flow in fractured systems, first the first time, with fully coupled thermal-hydraulic-mechanical (THM) properties. The impact of gas adsorption, real gas properties, gas flow in nano-scale pore space and geomechanics effects on total gas flow capacity are investigated. We also showed that by elevating shale rock temperature, the characteristic of gas adsorption behavior can be substantially altered.
