The LNG plant managed by the Angola LNG consortium (Eni’s interest 13.6%) started up and delivered its first cargo in June 2013. The plant envisages the development of 10,594 bcf of gas in 30 years.

In 2013 the East Hub project was sanctioned in the Block 15/06, with an estimated mineral potential of over 230 million barrels. The development program includes the drilling of submarine wells that were linked to an FPSO with a capacity of 80 kboe/d. Peak production of 55 kbbl/d is expected in 2017. Development activities progressed at the West Hub project, with start-up expected at the end of 2014.

In Block 0 (Eni’s interest 9.8%), activities progressed to reduce flaring gas at the Nemba field. In 2015 once completed flared gas is expected to decrease by approximately 85% from current level. 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.

In the Block 14 KA/IMI (Eni’s interest 10%) the development activities progressed at the Lianzi field by means of the linkage to the existing production facilities.

The second phase of Kizomba satellites in the Development Area of former Block 15 (Eni’s interest 20%) 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.


Exploration activities yielded positive results in the offshore block Marine XII (Eni operator with a 65% interest) with the oil and gas discovery and the appraisal of the Nené Marine field and with the appraisal of the gas and condensates Litchendjili discovery. The overall discoveries potential is estimated in 2.5 billion boe in place. The block has a further significant oil and gas residual amount that will be assessed by the next exploratory and delineation campaign. The proximity to existing facilities, good productivity of reservoir and low cost will allow to fast track development, targeting start-up in 2015.

In 2013 Eni acquired the operatorship of Ngolo exploration block, which is part of the Cuvette Basin, in the joint venture with the Congolese state company Société Nationale des Pétroles du Congo (SNPC). Exploration activities will take place over a period of 10 years. The Cuvette Basin is one of the new themes of frontier exploration activities in Africa.

During the year, Eni redefined with the relevant authorities the extension of Madingo, Marine VI and Marine VII exploration and development permits, with the aligning of expiring date within the period 2034-2039, the dilution of Eni’s stake and an acquisition interest of a new high potential exploration permit. The approval of the relevant authorities is in progress.

Activities on the M’Boundi field (Eni operator with an 83% interest) moved forward with the application of Eni advanced recovery techniques and a design to monetize associated gas. Gas is sold under long-term contracts to power plants in the area including the CEC Centrale Electrique du Congo (Eni’s interest 20%) with a 300 MW generation capacity. These facilities will also receive in the future gas from the offshore discoveries of the Marine XII permit. In 2013 M’Boundi contractual supplies were approximately 106 mmcf/d (approximately 17 kboe/d net to Eni). Additional gas production will be re-injected within the Eni’s zero gas flaring programs.

During the year activities progressed to support the population in M’Boundi area. The social project for 25,000 people provides to improve education, health, access to water and energy.

Development program progressed at the Litchendjili sanctioned project in the block Marine XII.

The start-up is expected by the end of 2015, with a production plateau of approximately 12 kboe/d net to Eni. Production will also feed the CEC power station.


On July 26, 2013, Eni concluded the sale of a 28.57% interest in Eni East Africa (EEA) to China National Petroleum Corporation (CNPC). EEA retains a 70% interest in the Area 4 mineral property, located offshore of Mozambique. CNPC indirectly acquires, through its equity investment in Eni East Africa, a 20% interest in Area 4, while Eni retains operatorship and a 50% interest through the remaining stake. The total consideration was equal to €3,386 million (for further information see “Financial review”).

The exploration campaign of the year regarded the appraisal of the Mamba and Coral discoveries. In particular, the delineation of Mamba discovery used the results of the implementation of a propriety process, which includes a study on reservoir characterization, data processing (e-dva™) and analyses of seismic scale.

In 2013 Eni made the Agulha discovery, the tenth discovery in a new exploration prospect located in the southern part of Area 4. Management estimates that Area 4 may contain up to 2,650 billion cubic meters of gas in place. In 2014, Eni will continue appraisal activities, particularly regarding the new exploration prospect, where the drilling of two to three additional wells is planned.

Leveraging on Eni’s cooperation model, the construction of a gas fired power plant for domestic consumption is being planned with the support of the Mozambican government.

In addition, a significant program of ecosystems evaluation and the analysis of biodiversity started in the country. This program will be included in the development project of recent discoveries.

Eni continues its recruitment and local training program in order to support the activities of hydrocarbons exploration in the Country. In particular the training program that started with the University of Mozambique involved 75 students during the year.


In the OML 125 block (Eni operator with an 85% interest), the Abo – Phase 3 project started-up, with production of approximately 5 kboe/d net to Eni. This project was sanctioned at the end of 2012 and was used an innovative technology for the installation of the intelligent control at the producing wells for simultaneous production start-up from the different reservoir levels. This technology allowed a fast track installation with significant savings.

Main activities progressed to support gas production to feed the Bonny liquefaction plant: (i) in the OMLs 60, 61, 62 and 63 blocks (Eni operator with a 20% interest), the Ogbainbiri flowstation was completed with a decline in flared gas of approximately 5 mmcf/d. This facility ensured to treat natural gas production of Ogbainbiri field. In the year, flaring down program includes a reduction of approximately 50 mmcf/d of gas flared leveraging on the upgrade of Idu flowstation completed at the end of 2012; as well as flaring down of Akri with a reduction of approximately 25 mmcf/d of gas flared; (ii) in the OML 28 block (Eni’s interest 5%), within the integrated oil and natural gas project in the Gbaran-Ubie area, the drilling campaign was completed. The development plan provides for the construction of a Central Processing Facility (CPF) with a treatment capacity of approximately 1 bcf/d of gas and 120 kbbl/d of liquids. Further development phases are planned to put in production the residual mineral potential in the area.

Other activity during the year concerned: (i) the Forkados-Yokri field (Eni’s interest 5%). The project includes the drilling of 24 producing wells, the upgrading of existing flowstations and the construction of transport facilities; (ii) Bonga NW field in the OML 118 block (Eni’s interest 12.5%). The activities include the drilling and completion of producing and infilling wells; (iii) programs to support local development for improving access to health and education and initiatives in agriculture development; (iv) technical support from the ESP Excellence Centre for data performance analysis in different production site of the country. Real-time monitoring at the producing wells allowed to avoid possible disruptions.

Eni holds a 10.4% interest in the Nigeria LNG Ltd joint venture which runs the Bonny liquefaction plant, located in the Eastern Niger Delta. The plant has a design treatment capacity of approximately 1,236 bcf/y of feed gas corresponding to a production of 22 mmtonnes/y of LNG on six trains. The seventh unit is being engineered as it is in the planning phase. When fully operational, total capacity will amount to approximately 30 mmtonnes/y of LNG, corresponding to a feedstock of approximately 1,624 bcf/y. Natural gas supplies to the plant are provided under gas supply agreements with a 20-year term from the SPDC jv (Eni’s interest 5%) and the NAOC JV, the latter operating the OMLs 60, 61, 62 and 63 blocks with an overall amount of approximately 2,825 mmcf/d (approximately 268 mmcf/d net to Eni corresponding to approximately 49 kboe/d). LNG production is sold under long-term contracts and exported to European and American markets by the Bonny Gas Transport fleet, wholly owned by Nigeria LNG Co.



On September 11, 2013, following the completion, test and delivery of all infrastructures, the first oil from the giant Kashagan (Eni’s interest 16.81%) field was produced. From October 2013 production has been halted due to a technical issue that occurred to the pipeline transporting acid gas from offshore to onshore facilities, without any impact on the environment and local communities. Recovery activities are ongoing. Management believes that from 2015 field production will recover to the originally expected level and the field contribution to Eni’s production profile for the year 2014 has been prudently assumed to be marginal.

The Phase 1 (Experimental Program) is targeting an initial production capacity of 150 kbbl/d; when the second treatment offshore train and compression facilities for gas reinjection will be completed and put online enabling to increase the production capacity up to 370 kbbl/d. The partners are planning to further increase available production capacity up to 450 kbbl/d by installing additional gas compression capacity for re-injection in the reservoir. The partners submitted the scheme of this additional phase to the relevant Kazakh Authorities.

In 2013 Eni submitted the development program of the Western section of the nearby Kalamkas discovery to the authorities. Sanction is expected in 2014 to start-up with the FEED phase.

Eni continues its commitment in the protection of the environment and ecosystems in the Caspian area with the integrated program for the management of biodiversity in the Ural Delta (Ural River Park Project – URPP). The project is almost completed and Eni’s aim to include it in the Man and Biosphere Program of UNESCO with positive consent of Kazakh Authority.

Within the agreement signed with the relevant authorities, Eni continues its training program for Kazakh resources management positions.

As of December 31, 2013, the aggregate costs incurred by Eni for the Kashagan project capitalized in the financial statements amounted to $8.2 billion (€5.9 billion at the EUR/USD exchange rate of December 31, 2013). This capitalized amount included: (i) $6.1 billion relating to expenditure incurred by Eni for the development of the oilfield; and (ii) $2.1 billion relating primarily to accrue finance charges and expenditures for the acquisition of interests in the North Caspian Sea PSA consortium from exiting partners upon exercise of pre-emption rights in previous years.

As of December 31, 2013 Eni’s proved reserves booked for the Kashagan field amounted to 565 mmboe, barely unchanged from 2012.


The Expansion Project of the Karachaganak field (Eni’s interest 29.25%) is currently under study. The project is aimed for a further developing gas and condensates reserves by means of the installation, in stages, of gas treatment plants and re-injection facilities to support liquids production plateau and increase gas sales. The development plan to increase re-injection capacity is currently in the phase of technical and marketing discussion to be presented to the relevant Authorities, with FEED expected in 2014.

In 2013 Eni launched an environmental monitoring program to identify the best available monitoring operations for biodiversity protection. Eni continues its commitment to support local communities by means of the construction of schools and educational facilities as well as health assistance for the villages located in the nearby area of Karachaganak.

As of December 31, 2013, Eni’s proved reserves booked for the Karachaganak field amounted to 470 mmboe, barely unchanged from 2012.
