2. Decomposition does not stop when the oxygen is gone.
3. The oil continues migrating in porous and permeable rocks.
4. The traps are important steps in the process of oil accumulation.
5. Structural geology is the subject for the students to miss.
6. Structural traps are of two types.
7. Stratigraphic traps are the ones that occur by nature.
8. It takes thousands of years for the petroleum to be made.
9. There are some specific conditions for the organisms to be met.

6. The organic matter begins to decompose.
7. Kerogen is broken down.
8. The petroleum will stop migrating if rocks are not porous or permeable.
9. Dead organisms accumulate on the ocean floor.
10. The petroleum will collect in a trap.
11. Kerogen is altered through high temperature and high pressure.
12. The petroleum will migrate in the rocks which are porous and permeable enough.
