Oil and Natural Gas Flashcards
1
Q
Maturation
A
The process through which organic materials are converted into oil and gas by temperature and pressure
2
Q
Migration
A
The movement of oil and gas from the source rock to the reservoir rock
3
Q
Reservoir Rock
A
Porous and permeable rock capable of storing large quantities of oil and gas
4
Q
Cap Rock
A
Impermeable rock above the reservoir rock that stops further migration
