It's not teeny, it's Eni -- and it's huge. One of Italy's largest companies, Eni operates in the oil and natural gas, petrochemicals, and oil field services industries and has expanded into power generation. Its main subsidiaries and affiliates include EniPower (power generation), Italgas (natural gas transmission), Saipem (oil field services), pipeline operator Snam Rete Gas, and Snamprogetti (contracting, engineering). As one of the world's leading oil enterprises, in 2010 Eni had proved reserves of 6.8 billion barrels of oil equivalent, most of it in Italy and in Africa. The Italian government owns 27% of Eni.
