➪ The natural gas, being lightest, occupies the top of the trap and is underlain by the oil and then the water.

➪ A layer of impermeable rock, called the cap rock, prevents the upward or lateral escape of the petroleum.

➪ That part of the trap actually occupied by the oil and gas is called the petroleum reservoir.
