viscosity which increased, the SARA analysis of the California oil sample
showed a decrease in saturates and aromatics while a substantial increase
of asphaltenes in the anode region. For the Canadian oil sample, as shown
in Figure 2.48, there was a significant increase in the saturate content and
a significant decrease in the asphaltene content of the oil both at the anode
and cathode regions. The aromatic and the resin contents do not show as
large a change from the control.
