英文摘要	Stray gas migration resulting from oil and gas operations can have negative impacts on shallow groundwater resources and the atmosphere. The movement and architecture of free-phase gas can have important implications on the expected effect of stray gas migration. For example, free-phase gas can become trapped in the subsurface and then dissolve, or gas flow can reach the surface. In this study, intermediate-scale laboratory experiments in quasi-two-dimensional flow cells employing a modified light transmission method were used to better understand free-phase gas migration under gravity-destabilized conditions. Quantification of both gas movement and saturation improves our understanding of the expected source architecture of stray gas. The results of this study show that gas flow became discontinuous away from the source and that gas saturations decreased immediately following the stoppage of a leak. The results of this study will lead to enhanced knowledge concerning mass transfer to groundwater both spatially and temporally. © 2020 Elsevier Ltd
