Production

At the end of 2013, Eni’s operations in Nigeria were carried out in a developed and non-developed area covering 36,285 square kilometres (with Eni’s share amounting to 7,646 square kilometres), concentrated in both onshore and offshore areas of the Niger Delta, with a total of 41 mining leases (eni is the operator in 11 mining leases – 11, 823 sqkm). Eni’s operations in Nigeria are regulated by Production Sharing Agreements and Concession contracts and, in the case of two leases, by service contracts where Eni is the contractor on behalf of Nigerian state-owned companies. In 2013 Eni’s share of hydrocarbon production amounted to 125,100 barrels of oil equivalent per day (boe/day), including 72,000 barrels/day of crude and condensates.

In the production/development phase naoc is the operator, in both the onshore and offshore areas, of four oil mining leases (OML) 60, 61, 62 and 63 (20% participating interest).

naoc’s production asset includes 11 No. flowstations, 2 No. Gas Plants, 1 No. Oil Center  and 1 No. Export Terminal of 3,558,000 barrels storage capacity with 2 single point mooring-bouys for loading tankers (Brass oil terminal). The flow stations and Oil Center Plants are connected to the Terminal in Brass through a 460 km pipeline network, while an additional 180 km pipeline carries NGL and fuel gas to Indorama Petrochemical Company, at Eleme. The gas gathering pipelines linking Kwale through Akri – Ob-Ob to N-LNG spans 170 Km.  Overall, naoc’s trunklines and pipelines network accounts for more than 3,000 km.

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.

nae equity production in 2013 is in the range of 33,000 boepd, coming mainly from operated field of Abo in block OML 125. The concession, together with OML134, is operated by nae, with OANDO E&P Ltd as its partner, under a Production Sharing Contract with NNPC signed in 1993 and valid for 30 years.

First oil from the Abo field was produced through the Abo FPSO in April 2003. With it, nae set the record of being the first company to produce oil from the nation’s deep offshore. Abo Extension development was carried out between 2006 and 2009 with the drilling and tie-in of Abo 10 and 11 production wells plus Abo 9 gas injector. Peak production of 37,300 bopd (100%) was achieved from the field in February 2010.

Having identified a further upside in the resources of Abo field, mostly thanks to the results of an innovative 4D seismic, in 2013 nae started the execution of Abo Phase 3 development, expected to contribute to a further peak in oil production of the field and extending its life.

During 2011, nae acquired a 50 percent share and Operatorship of OPL 245 ultra deep water block, where Shell Nigeria E&P Co (SNEPCo) is the other partner with 50 percent share.

In April 2011, nae also acquired a 49% participating interest in OPL 2009 block from GPDC. nae is the technical operator of the block.

nae as operator, has acquired 6734.75 km of 2D seismic, 5707 km2 of 3D seismic, 223 km² of 4D and drilled so far six exploratory wells in OML 125 and OML 134, two exploratory well in OPL 2009 and three exploratory wells in OPL 245.

In addition, nae has 12,5% equity in blocks OML 118, where prolific Bonga main field is in production since 2005 and two new development projects (Bonga North and Bonga Sw) are ongoing, and OML 135, both operated by SNEPCo.

Utilizing a fast track strategy, in OML 119 aenr produced first oil in December 2001 – 10 months after the signing of the contract, three months ahead of schedule and achieved a record time-to-market.

In 2003, an amendment to the Service Contract was signed and the contract production cap was elevated to a limit of 214 MSTB.  To date 12 wells (6 in Okpoho, 6 in Okono) have been drilled, completed and tied in to the FPSO Mystras.

On August 27th 2009, aenr and NPDC signed a Memorandum of Understanding for the drilling, completion and hook-up of the Okono 6 and 7 wells, eventually tied back to production in 2012.
