Angola
Eni has been present in Angola since 1980. In 2013, Eni’s production amounted to 87 kboe/d. Eni’s activities are concentrated in the conventional and deep offshore, over a developed and undeveloped acreage of 21,489 square kilometers (4,443 square kilometers net to Eni).
The main producing blocks with Eni’s participation are: (i) Block 0 in Cabinda (Eni’s interest 9.8%) North of the Angolan coast; (ii) Development Areas in the former Block 3 (Eni’s interest 12%) in the offshore of the Congo Basin; (iii) Development Areas in the Block 14 (Eni’s interest 20%) in the deep offshore west of Block 0; (iv) Development Areas in the former Block 15 (Eni’s interest 20%) in the deep offshore of the Congo Basin; and (v) Block 15/06 (Eni operator with a 35% interest) with ongoing development activities.
Eni retains interests in other non producing concessions, particularly the Lianzi Development Area (Block 14K/A Imi Unit Area - Eni’s interest 10%), Block 35/11 (Eni operator with a 30% interest) and in Block 3/05-A (Eni’s interest 12%), onshore Cabinda North (Eni’s interest 15%) and the Open Areas of Block 2 awarded to the Gas Project (Eni’s interest 20%).
Exploration and production activities in Angola are regulated by concessions and PSAs.
In the next four years, management expects to increase Eni’s production in Angola reflecting additions from ongoing development projects.
Block 0
Production Block 0 is divided into Areas A and B. In 2013, production from this block amounted to approximately 303 kbbl/d (approximately 30 kbbl/d net to Eni). Oil production from Area A, deriving mainly from the Takula, Malongo and Mafumeira fields amounted to approximately 19 kbbl/d net to Eni. Production of Area B derives mainly from the Bomboco, Kokongo, Lomba, N’Dola, Nemba and Sanha fields, and amounted to approximately 11 kbbl/d net to Eni.
Development Activities progressed to reduce flaring gas at the Nemba field in the Area B. In 2015 once completed flared gas is expected to decrease by approximately 85% from current level. In the Area A, the development activities of the Mafumeira field included the installation of production and treatment platforms and underwater linkage. Start-up is expected by the end of 2015. Infilling activities and near-field exploration are underway on the whole block in order to mitigate the natural field production decline.
Block 3
Production Block 3 is divided into three production offshore areas. In 2013, production from this block amounted to approximately 50 kbbl/d (approximately 3 kbbl/d net to Eni).
Development Concept Definition studies are underway in the Punja and Caco-Gazela discoveries.
Block 14
Production In 2013, Development Areas in Block 14 produced approximately 139 kbbl/d (approximately 18 kbbl/d net to Eni), accounting for approximately 20% of Eni’s production in Angola. It is one of the most fruitful areas in the West African offshore, recording 9 commercial discoveries to date. Its main fields are: (i) Kuito, started-up in 1999, flowing at approximately 3 kbbl/d net to Eni in 2013; (ii) Landana and Tombua, started-up in 2009, flowing at approximately 9 kboe/d net to Eni. Production is supported by a Compliant Piled Tower (CPT) provided with treatment facilities; (iii) Benguela-Belize/Lobito-Tomboco, started-up in 2006, flowing at approximately 6 kbbl/d net to Eni. Production from these fields is supported by a CPT provided with treatment facilities for Benguela-Belize and an underwater linkage system for Lobito-Tomboco. Oil produced is treated at the Malongo plant. Associated gas of the area will be re-injected in the Nemba reservoir and later it will be delivered via a transport facility to the A-LNG liquefaction plant (see below).
Development The activities concerned mainly the Lianzi field in the Block 14K/A Imi (Eni’s interest 10%), through the linkage to the existing facilities. Concept Selection activities are ongoing at the Malange and Lucapa recent discoveries.
Block 15
Production The Block produced approximately 385 kbbl/d (approximately 33 kbbl/d net to Eni) in 2013. Block 15 is considered the most interesting area in the West African offshore with recoverable reserves estimated at 2.55 bbbl of oil. Production derives mainly from the Kizomba discovery area with: (i) the Hungo/Chocalho fields, started-up in August 2004 as part of phase A of the global development plan of the Kizomba reserves; (ii) the Kissanje/Dikanza fields, started-up in July 2005, as part of Phase Kizomba B; (iii) satellites Kizomba Phase 1 project, started-up in 2012. These fields are operated by FPSO units. In 2013, the fields of Kizomba area produced approximately 278 kbbl/d (approximately 27 kbbl/d net to Eni).
Other main fields in Block 15 are Mondo and Saxi/Batuque fields which produced approximately 107 kbbl/d (approximately 6 kbbl/d net to Eni) in 2013.
In the medium term, phased development of satellite discoveries will mantain the current production plateau of the area.
Development The second phase of Kizomba satellites progressed as planned. The project provides to put into production three additional discoveries that will be linked to the existing FPSO. Start-up is expected at the end of 2015.
Block 15/06
The activities concerned the development of two West Hub projects, sanctioned in 2010, and East Hub project, sanctioned in 2013.
The West Hub project includes the development of the Sangos, Cinguvu and Mpungi discoveries that will be added in the consecutive phase of the Vandumbu discoveries, which increases the potential of the hub to up to 200 mmbbl. First phase of West Hub project provides for the drilling of 21 subsea wells (12 producers and 9 injectors) linked to an FPSO unit with a capacity of 100 kbbl/d with start-up expected at the end of 2014 that will be added of the Vandumbu discoveries connected to the same FPSO. Peak production is expected at 80 kbbl/d in 2016.
The East Hub project provides for the development of the Cabaça South-East discovery with potential resources estimated at over 230 mmbbl. Development activity provides for the drilling of 10 subsea wells which will be linked to an FPSO unit with a capacity of 80 kbbl/d. Peak production is expected at 55 kbbl/d in 2017.
Further development phases are planned to start-up nearby discoveries.
Exploration activities yielded positive results in the area with the oil Vandumbu 1 discovery.
The LNG business in Angola
During the year, the LNG plant managed by the Angola LNG consortium (Eni’s interest 13.6%) started-up and delivered its first cargo in June 2013. LNG plant has a processing capacity of approximately 1.1 bcf/d of natural gas, producing 5.2 mmtonnes/y of LNG and over 50 kbbl/d of condensates and LPG. The plant envisages the development of 10,594 bcf of gas in 30 years.
Eni is part of the Gas Project (Eni’s interest 20%) that will apprise and explore further potential gas discoveries to support the feasibility of a second LNG train or other alternative projects to market gas and associated liquids.
