Note:
* This is not an exhaustive list, and there are many other significant oil fields in these areas.
* Oil recovery figures are estimates and may vary depending on the source.
* Trap types are not mutually exclusive, and many fields exhibit combinations of different trap types.
* The terms "Giant" and "Large" refer to field size, with giants typically recovering more than 500 million barrels of oil.
This information should provide a general overview of the major oil fields and trap types in these regions. It is important to consult specific geological data for more detailed information about individual fields.
