-The oil fields can be secundarious, when has been formed in a remote location and flows to the place where is now, thismovement changes its properties. It is very important because the continuous arrival of hydrocarbons to the tramp of petroleum allow the accumulation of this, in a quantity and concentrationimportant for doing very economical the extraction of the crude.
