Abstract
Magnetic resonance imaging is used to investigate, at the pore scale, the dissolution and mobilisation of discrete non-aqueous phase liquid (octanol) ganglia trapped within porous media by capillary forces, by a mobile aqueous phase. Dissolution Bs observed to be described by a m ass-transfer limited model, Mobilisation of entrapped ganglia commence s at lower flowrates when a surfactant is introduced into the mobile a queous phase.
