An analytical formulation of the relaxation time corresponding to water removal during clean-up processes following hydraulic fracture stimulation is presented. The dynamics of advancement of the wetting...

... pressure drop between gas located in the fracture (low capillary pressure medium) and the gas in the inorganic matrix (large capillary pressure medium) would result in imbibition of a considerable amount of water and therefore entrapment of water. Tyagi et al. (2007) show that the relative permeability...

... and is commonly used in larger scale reservoir simulations ( Chen 2006 ). However, obtaining a closed system of averaged equations requires the introduction of constitutive relationships between the different parameters, such as capillary pressure-saturation and relative permeability-saturation. For instance...

ABSTRACT A number of laboratory studies on coalbed methane (CBM) have provided data for the relative permeability of coal to gas and water, which are needed to analyze CBM reservoirs, particularly in numerical simulation. The relative permeability curves of coal to gas and water are determined...
