Before a petroleum system can be investigated, it must be identified as being present.
Petroleum system identification
To identify a petroleum system, the explorationist must find some petroleum. Any quantity of petroleum, no matter how small, is proof of a petroleum system. An oil or gas seep, a show of oil or gas in a well, or an oil or gas accumulation demonstrates the presence of a petroleum system.
Procedure: identifying a petroleum system
The table below outlines the steps required to identify a petroleum system.
Step | Task | |||
---|---|---|---|---|
1 | Find some indication of the presence of petroleum. | |||
2 | Determine the size of the petroleum system by the following series of steps:
| |||
Step | Task | |||
a | Group genetically related occurrences of petroleum by using geochemical characteristics and stratigraphic occurrences. | |||
b | Identify the source using petroleum-source rock correlations. | |||
c | Locate the general area of the pod of active source rock responsible for the genetically related petroleum occurrences. | |||
d | Make a table of accumulations to determine the amount of hydrocarbons in the petroleum system and which reservoir rock contains the most petroleum. |
3Name the petroleum system.
