In page Enrico Mattei:

"

In 1949 Mattei made an astonishing public announcement: the soil of the Po Valley in Northern Italy was rich in oil and methane, and Italy would solve all its energy needs using its own resources. Through the Italian press, he then encouraged the idea that the nation (still suffering from the consequences of World War II) would soon become rich. Agip's financial value immediately grew in the stock exchanges, and the company (owned by the state but operating as a private company) became at once solid and important. The reality was a little different; in the territory of Cortemaggiore, in the Valley of Po, a certain amount of methane had been found together with a small quantity of oil.[citation needed]
