The work represents a synthesis published and printed in two volumes (the 1st volume in 2002, the second one, in 2004) under the aegis of Mica Valahie Publishing House in Bucharest. Being elaborated on the basis of some documents discovered in the Romanian and foreign archives, the two volumes cover the period up to 1929 in the first volume and the period from 1929 to 2005 in the second one. The paper reveals the role and place of Romanian oil in the evolution of the national and worldwide history, especially during the World War between 1939 and 1945 and in the development of the so-called “cold war”. The book insists upon the prospects of the specific “black gold” evolution.In the addendum there are to be found some interesting documents and the complete bibliography of oil.
