Abstract: AbstractNatural surface gas seeps provide a significant input of greenhouse gas emissions into the Earth’s atmosphere and hydrosphere. The gas flux is controlled by the properties of underlying fluid‐escape conduits, which are present within sedimentary basins globally. These conduits permit pressure‐driven fluid flow, hydraulically connecting deeper strata with the Earth’s surface; however they can only be fully resolved at sub‐seismic scale. Here, a novel ‘minus cement and matrix permeability’ method using three‐dimensional X...
