In the oil industry, in general, and in Mexico, in particular, the use of heavy
crudes in the refining process has increased considerably. The processing of these
heavy crudes implies an important technological challenge, and their transportation can
sometimes be complicated. Among the alternatives for transporting this type of crude is
the formation of invert emulsions in which ILs can play an important role, which is
discussed in this chapter.
