Quizplus · Accepted Answer

Oil can be found in sedimentary rock formations that are buried several kilometers below the surface. The greatest depth at which oil is found is about 6.5 km below the surface. This is because oil is formed from the remains of organic matter that have been buried and subjected to heat and pressure over millions of years. At depths greater than 6.5 km, the temperature and pressure are too high for oil to form and remain stable.
