Abstract:
Traditional porosity-based models for estimating gas diffusivity in geologic media often fail to account for the effects of temperature-dependent sorption. This work presents a revised framework for diffusivity estimation that incorporates temperature effects on gas sorption, providing more accurate predictions of gas transport in subsurface environments across a range of temperatures.
