Fuel, 1989•ElsevierVenezuelan crude oils of different viscosity were studied by pulsed nmr. Four phases with
different microdynamical properties could be distinguished through the measurement of
magnetic relaxation times T1 and T2. Their temperature dependence showed the known
BPP behaviour with a wide correlation time distribution caused by magnetic dipolar and
electron-proton interactions. When the temperature was increased, the transformation from a
viscous phase to a more liquid phase could be observed.
