Pressure perturbations from geologic carbon sequestration: Area-of-review boundaries and borehole leakage driving forces

摘要: Abstract We investigate the possibility that brine could be displaced upward into potable water through wells. Because of large volumes CO 2 to injected, influence zone elevated pressure on potential conduits such as well boreholes extend many kilometers from injection site—farther than plume itself. The traditional approach address leakage related fluid is set an area fixed radius around well/zone and examine wells other potentially open pathways located in “Area-of-Review” (AoR). This suggests AoR needs defined terms for a given perturbation drive flow any system rather some arbitrary rise. present analysis focuses changes density/salinity fluids leaking wellbore.
