This list of oil fields includes some major oil fields of the past and present. Countries by proven oil reserves 2017. The list is incomplete; there are more than 25,000 oil and gas fields of all sizes in the world. [1] However, 94 % of known oil is concentrated in fewer than 1,500 giant and major fields. [2]
In common usage, deposits rich in oil are known as oil fields, and deposits rich in natural gas are called natural gas fields. In general, organic sediments buried in depths of 1,000 m to 6,000 m (at temperatures of 60 ° C to 150 °C) generate oil, while sediments buried deeper and at higher temperatures generate natural gas.
