Question

why is a layer of oil is formed between natural gas amd water ​

Answer 1

Answer:

The source rock is the rock that contains the kerogen that the oil and gas forms from. The reservoir rock is the porous, permeable rock layer or layers that hold the oil and gas. ... This migration occurs because oil and gas are less dense than water.

Answer 2

Since oil is light, it floats above the water layer, which is why we find the oil layer above it. Oil floats on the surface of the water because it has a lower density than water.

Why is the layer of oil formed?

• In shallow seas millions of years ago, algae and plants coexisted.
• The organic material decayed, sank to the seafloor, mingled with other sediments, and was buried.
• The remains of these animals underwent a transformation into what we now know as fossil fuels over millions of years at great pressure and high temperature.
• Oil is found above the water layer because it floats above the water because it is lighter than water.
• Natural gas is frequently discovered on top of the oil since it is lighter.
• Like oil, some natural gas also flows freely to wells because the subsurface reservoir's inherent pressure pushes the gas through the rocks there.
