A unique designation or name is important to identify a person, place, item, or idea. As geologists, we name rock units, fossils, uplifts, and basins. The name for a specific petroleum system separates it from other [[petroleum systems]] and other geologic names.

The name of a petroleum system contains several parts that name the hydrocarbon fluid system:

The name of a [[petroleum system]] contains several parts that name the hydrocarbon fluid system:

* The source rock in the pod of active source rock

* The [[source rock]] in the pod of active source rock

* The name of the reservoir rock that contains the largest volume of in-place petroleum

* The name of the [[reservoir]] rock that contains the largest volume of in-place petroleum

* The symbol expressing the level of certainty

* The symbol expressing the level of certainty

==Level of certainty==

==Level of certainty==

A petroleum system can be identified at three levels of certainty: known, hypothetical, and speculative. The level of certainty indicates the confidence for which a particular pod of mature source rock has generated the hydrocarbons in an accumulation. At the end of the system's name, the level of certainty is indicated by (!) for known, (.) for hypothetical, and (?) for speculative.
