Description

Petroleum is found in the microscopic pores of sedimentary rocks such as sandstone and limestone. Not all of the pores in a rock will contain petroleum - some will be filled with water or brine that is saturated with minerals. Seismic surveys are used to try to predict where oilfields may be but the only way of making certain is by drilling.
