In 2012, the Upstream Gas Function initiated the process of certifying the reserves of the assets it had under development, for which the Function used an independent certifier, DeGolyer & McNaughton. On the basis of the assessment performed in 2012 and taking account of the disposal of the stake held in SeverEnergia in 2013, Enel’s share is equal to 18 million barrels of oil equivalent of proven reserves and 46 million barrels of oil equivalent of proven and probable reserves. Projects under development at the end of 2013 are located:

  • in Algeria, where the Group is participating in hydrocarbon exploration and production licenses with a stake of 18.4% of the “Isarene” permit in partnership with Petroceltic International and Sonatrach (a Algerian state-owned company) and 13.5% of the “South-East Illizi” permit in partnership with Repsol (as the operator) and GDF Suez;
  • in Egypt, where the Group has a 10% share, in partnership with Total (as the operator) and BG, in exploration activities in an offshore field off the Nile Delta;
  • in Italy, through Enel Longanesi Development, where the Group has 12 exploration applications, 5 permits and 1 concession application. In 2013, continuing its studies, the Group entered a joint venture with Mac Oil, acquiring 70% of the exploration permit for Montottone, in the Marche region, and submitted two new applications for offshore exploration permits in the Gulf of Taranto and the Adriatic Sea. The authorization procedure for the application for the hydrocarbon extraction concession at Bagnacavallo is pending, with production expected to begin at the end of 2016.
