Many world oil companies such as Exxon Mobil, Chevron, BP, Amoco, Conoco, Arco are from Standard Oil Company. An oil company owned by the Rockefeller family.
These oil companies exploit oil and gas all over the world including Africa and Indonesia. Sometimes they make US president that they help in presidential campaign to make “War for Oil” such as to Iraq. They also try to attack Libya to get its oil but fail until now.
