Characterisation of tight sandstone using NMR T₂ response : permeability and capillary pressure

Nuclear magnetic resonance T₂ measurements for estimating permeability and drainage capillary pressure, particularly in tight sandstones, are investigated. An assessment of popular permeability models suggested that permeability is hard to predict universally. The best a model may achieve, compared...
