Abstract
Venezuelan crude oils of different viscosity were studied by pulsed n.m.r.. Four phases with different microdynamical properties could be distinguished through the measurement of magnetic relaxation times T 1 and T 2. 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.
