there is a growing need for oil in the world. So people are looking for it everywhere. They look for oil

in deserts, in the mountains and under the sea. Quite often they find nothing, but the search for oil always

goes on. What are the largest oil producers in the world? The U.S, the U.S.S.R., and countries of the
