Item 13
For the diagram below, assume fracking has not been used with the oil and gas well.

The figure presents a diagram of 6 rock layers that contain oil and natural gas. Beginning at the bottom and moving upwards, the rock layers are as follows. Rock layer D is at the bottom, and rock layer C is directly above it. Oil is located in the upper portion of rock layer C, and natural gas, or C H 4, is located directly above the oil, still in rock layer C. Rock layer B is located directly above rock layer C, and it contains the same type of rock as layer D. Moving upward, the next two rock layers are unlabeled. Rock layer A lies at the top, and it contains the same type of rock as layers B and D. A well has been drilled down into the area of natural gas, or C H 4.

There are different kinds of rocks. The Rock layer that can be porous but must have very low to no permeability is Clay.

  • Clay is known to be a type of soil that has high porosity but little is found of permeability.

This implies that this low permeability  therefore acts as a barrier for water to be unable to flow through and the water found within it is said to be trapped.

The type of rock with low permeable are unfractured intrusive igneous and metamorphic rocks, sandstone, limestone and others.
