Give Russian equivalents to the following English ones.

gasoline fold
opening up fault
to recover = to mine = to produce thrust faults
oil = petroleum unconformity
mixture salt dome
decompose fracture
hydrocarbons trap
organic matter sediment
specific conditions accumulate

Give definitions to the following terms.


petroleum kerogen
crude oil porous
natural gas permeable
hydrocarbons source rock
migrate trap

State whether the following sentences are true or false.

1. A restricted basin is not the place for the kerogen to collect.

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.

10. Shorter hydrocarbon chains are oil.

Put the facts into the correct order showing how oil becomes oil.

1. Hydrocarbon chains are freed.

2. Kerogen is developed.

3. The matter becomes buried.

4. Longer chains break into shorter ones, and methane remains.

5. The petroleum is forced into nearby sediments.

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.
