Sept 4 (Reuters) - Italy's Eni (ENI.MI) signed on Monday an agreement to sell its unit Nigerian Agip Oil Company (NAOC) to Nigerian counterpart Oando (OANDO.LG), the group said in a statement, in the latest move by an energy giant out of the country. Eni's NAOC, which focuses on oil and gas exploration and production, has interests in four onshore blocks and two onshore exploration leases in Nigeria, the group said. Similar approvals have been held back by legal and political issues in Exxon's and Shell's assets sales. After the disposal of NAOC, in line with the firm's 2023-2026 plan, Eni will retain the unit's 5% stake in the Shell Production Development Company (SPDC) joint venture operated by Shell, the group added.
