Eni’s onshore operations

Eni operates in the onshore areas of the Niger Delta through its oldest subsidiary in Nigeria – the Nigerian Agip Oil Company (NAOC). NAOC operates under a joint venture agreement, popularly referred to as the NAOC JV. It is comprised of the Nigerian Petroleum Development Company (NPDC), with 60% interest, NAOC (20%), and Oando (20%).  

The JV’s concessions lie in areas that fall within the territories of four Nigerian states, namely Bayelsa, Delta, Imo and Rivers States, covering a total area of 5,313km2. 

The company’s operations in these four states is broadly categorized, according to terrain, into two areas, namely the Land Area (LAR) and the Swamp Area (SAR). Activities in Imo, Rivers, and some parts of Delta state fall under LAR, while those in Bayelsa and some other parts of Delta state (specifically Burutu and Bomadi Local Government Areas) fall under SAR. 

NAOC, on behalf of the JV, operates four onshore oil blocks - OML 60, OML 61, OML 62 and OML 63 – across these four states.  The company is also the operator of two onshore exploration leases, namely OPL 282, in which it holds a 90% interest, and OPL 135, in which it holds a 48% interest. 

In addition, NAOC holds a 5% participating interest in the Shell Production Development Company Joint Venture (SPDC JV). The other partners in this JV are Shell Petroleum Development Company (30%), NNPC (55%,) and Total E&P Nigeria (10%). SPDC is the operator of this JV. 

NAOC’s production assets include 11 flow stations, 2 Gas Plants, 1 Oil Center and 1 Export Terminal. The Export Terminal, located at Brass in Bayelsa State, has a storage capacity of 3,558,000 barrels, with 2 single point mooring-buoys for loading tankers.

The flow stations

The flow stations and Oil Center are connected to the Brass Oil Terminal through a 460 km pipeline network, while an additional 180 km pipeline network carries Natural Gas Liquids (NGL) and fuel gas to Indorama Petrochemical Company at Eleme in Rivers State.   

The gas gathering pipelines linking the company’s Gas Plants at Kwale in Delta State and Obiafu-Obrikom (Ob-Ob) in Rivers State, with a third under development in Akri in Imo State, together travel over 170 Km.   

Overall, NAOC’s extensive trunkline and pipeline network span more than 3,000 km across the Niger Delta. 

The flow stations have been expanded and retrofitted to take care of growth in operation and support gas gathering effort, as well as improve operational efficiency towards achieving the flare-down agenda of the company.
