A Fully Coupled Hydromechanical Model for CO₂ Sequestration in Coal Seam: the Roles of Multiphase Flow and Gas Dynamic Diffusion on Fluid Transfer and Coal Behavior

Figure 1

Results of relative permeability from Watanabe et al. [17], Fahad et al. [18], Bennion and Bachu [19], and Lian et al. [20]. Several traditional relative permeability models, such as the X-curve model [21], Corey model [22], and Brooks-Corey model [23] are also shown. (Note: For the same symbol, red refers to gas relative permeability, while blue refers to water relative permeability.)
