Quizplus · Accepted Answer

The greatest depth at which oil is found is about 6.5 km (4 miles) below the surface, in the Earth's crust. This is where the temperature and pressure conditions are ideal for the formation of petroleum from organic matter. Oil is not found at the Moho (the boundary between the Earth's crust and mantle) or at the base of the lithosphere (the rigid outer layer of the Earth including the crust and upper mantle).
