The petroleum system is a unifying concept that encompasses all of the disparate elements and processes of petroleum geology. Practical application of petroleum systems can be used in exploration, resource evaluation, and research.

The [[petroleum]] system is a unifying concept that encompasses all of the disparate elements and processes of petroleum geology, including: the essential elements ([[source]], [[reservoir]], [[seal]], and [[overburden rock]]) and processes ([[trap formation]], [[generation]]-[[migration]]-[[accumulation]]) and all genetically related petroleum that originated from one pod of active [[source rock]] and occurs in [[show]]s, [[seep]]s, or [[accumulation]]s;<ref name=Magoonanddow_1994>Magoon, L.

A petroleum system encompasses a pod of active [[source rock]] and all genetically related oil and gas accumulations. It includes all the geologic elements and processes that are essential if an oil and gas [[accumulation]] is to exist.

These essential elements and processes must be correctly placed in time and space so that organic matter included in a source rock can be converted into a petroleum accumulation. A petroleum system exists wherever all these essential elements and processes are known to occur or are thought to have a reasonable chance or probability to occur.
