In which layer will liquid petroleum be found in the oil trap shown in figure 4-1

Option (3)

Explanation:

In the given figure, it shows a structural anticlinal traps where the upper rock is a layer of impermeable shale and the below these oil layer is a porous reservoir rock. The petroleum oil is concentrated in the lower region above the reservoir rock and the natural gas is accumulated above this petroleum oil. These types of anticlinal traps are very common and highly significant to the hydrocarbon industries. These traps are long oval-shaped domes of land that are easily identified in topographic maps.

In the figure, the liquid petroleum is present is the layer D and layer C contains the natural gas.

Thus, the correct answer is option (3).
