Oil exploration is a particularly arduous venture involving geological evaluation and assessment. Modern geologists analyze surface rocks with the help of three tools to ascertain whether oil is indeed present below the surface. The first tool is sensitive gravity meters that survey changes in the earth’s gravitational pull, indicating the presence of oil.

Magnetometers are also deployed to gauge changes in the earth’s magnetic field that are caused by the flow of oil beneath the surface. Lastly, explorers can use seismology. The process involves sending shock waves through the surface of the soil, passing through the layers of rock, before finally being reflected back to the earth’s surface. The reflected waves are then assessed for variations in speed and strength caused by hydrocarbons.
