Mangoon and Dow (1994)
Natural system that encompasses pod of active source rock and all related oil and gas and which includes all the geologic element and processes that are essential if a hydrocarbon accumulation is to exist.
Magoon 1987
The Petroleum system emphasizes the genetic relation between a particular source rock and resulting petroleum accumulation……..
Secara garis besar Petroleum system dapat dibagi menjadi 2 sub systems yaitu :
1. Generative sub system
2. Migration and entrapment sub system
Migration and entrapment sub system
Element : Generated hydrocarbon
Processes :
Expulsion (Primary migration)
Source rock : Carrier bed
Expulsion model, expulsion and generation, expulsion Effeciency
Secondary migration
Within carrier bed to traps
Migration model, driving force, ristricting force, PC
Entrapment sub system
Element :
Migrated hydrocarbon
Trap geometry
Reservoir rocks
Seal rock
Processes :
Migration
Trapping
