Seplat has a 45% working interest in OMLs 4, 38 and 41 which are located in Edo and Delta States onshore Nigeria. Seplat is operator of the three blocks on behalf of the NPDC/Seplat Joint Venture and, to date, is the only company that has secured NPDC approval for operatorship over blocks acquired as part of recent divestment programmes by the major IOCs.

OML 4 covers an area of 267 km² and is located 78km North East of Warri, Delta State. The Oben field is located in OML 4 and is the main producing field on the block. Facilities on the block include a 60,000 bpd capacity flow station and a 90 MMscfd capacity non-associated gas plant. The gas plant exports gas to the Nigerian gas network via the ELPS. The Company is expected to complete installation and commissioning of a new 150 MMscfd gas processing plant in Oben by early 2015. Oil exports from the Oben flow station are routed via the Oben – Amukpe pipeline to the Amukpe facilities and onwards to either the Forcados terminal or Warri Refinery. Associated gas is handled at a 32 MMscfd gas compressor station that is owned by the NGC and leased by the Company, from where it is then exported via the local NGC grid that is connected to the Sapele power plant and Ajaokuta steel mills. Production operations and facilities are supported by the Oben Field Logistics Base. The Oben field in particular is central to the Company’s future gas expansion plans and is strategically located as an important gas hub with access to Nigeria’s main gas demand centres. The licence was renewed in 1989 for a further 30 years and is due to expire on 30 June 2019.

OML 38 covers an area of 2,094 km² and is located 48km North of Warri, Delta State. The Amukpe field is one of the three producing fields in the block. The second producing field, Ovhor, straddles OML 38 and OML 41. The Company commenced production from the third producing field, Okporhuru, in May 2013. There are three further discoveries on OML 38 that have not been brought into production, the Mosogar, Orogho and Jesse discoveries.  Facilities on the block include a 45,000 bpd capacity flow station located at Amukpe. In 2014 the Company commissioned a new liquid treatment facility (LTF) which is located adjacent to the flow station and has a 100,000 bpd capacity. The LTF has been designed and located to receive and de-water liquids production for the Oben, Amukpe and Sapele flow stations. The produced oil is then exported via the existing Amukpe – Rapele pipeline from and onwards to either the Forcados terminal or Warri Refinery. The licence was renewed in 1989 for a further 30 years expiring on 30 June 2019.

OML 41 covers an area of 291 km² and is located 50km from Warri, Delta State. The block contains two producing fields, Sapele and Ovhor (which straddles OML 41 and OML 38), and two discoveries with contingent resources, Ubaleme and Okoporo. Overlying the main productive reservoirs in the Sapele field is the Sapele Shallow discovery, a significant accumulation of oil that has remained largely undeveloped due to the heavier nature of the oil (21° API) relative to that in neighbouring blocks. The Company believes that full development of Sapele Shallow represents a material upside opportunity and intends to pursue this in the near term. Facilities on the block include a flow station with 60,000 bpd capacity, a 60 MMscfd capacity non associated gas plant and a 26 MMscfd NGC owned compressor station. Produced oil is exported via the Sapele – Amukpe delivery line to the Amukpe facilities and onwards to either the Forcados terminal or Warri Refinery. The condensate stream is combined with the oil for export and produced gas is exported via the NGC owned Oben-Sapele pipeline system which feeds into the Sapele power plant. The licence was renewed in 1989 for a further 30 years expiring on 30 June 2019.
