The '''temporal extent''' of the [[petroleum system]] is shown on the events chart and includes the age of the essential elements and processes, the preservation time, and the critical moment. By displaying together the time over which these separate events took place, the relation between forming and charging the traps containing the accumulations is easily evaluated.

A petroleum system events chart shows time on one axis and the essential elements and processes on the other. The time required for the [[Petroleum generation|generation]]-[[migration]]-[[accumulation]] process is the same as the age of the system. The chart also shows the preservation time and critical moment for the system. [[:file:petroleum-systems_fig3-6.png|Figure 4]] depicts the events chart for the fictitious Deer-Boar(.) petroleum system.
