Production and development

Seplat is operator of the three blocks, which together form one contract area, on behalf of the NPDC/Seplat Joint Venture. As operator, Seplat is empowered with running the day-to-day operations activities and is able to set production and operational improvement goals and lead exploration and appraisal activities, subject to the approval of its partner. Production is predominantly from seven fields, namely Amukpe, Oben, Okporhuru, Ovhor, Orogho, Sapele and Sapele Shallow, and the partners aim to bring additional fields onstream in the future.

Since acquiring the blocks in July 2010, the Company has consistently grown oil production capacity, primarily through the drilling of new wells and employing advanced and proven technologies to increase production in mature fields. The Company also became the first operator in the Niger Delta to install a LACT unit, enabling significantly improved measurement of produced oil prior to injection into the Trans Forcados Pipeline system. This has greatly reduced the reconciliation losses applied to the Company’s oil production to a level of approximately 10% to 12%, compared to an average of approximately 18% to 20% prior to installation of the LACT unit.

Alongside the oil business, the Company has also prioritised the commercialisation and development of the substantial gas reserves and resources identified at OMLs 4, 38 and 41 and is today a leading supplier of gas to the domestic market in Nigeria. Going forward, Seplat plans to further increase its gas production and processing capacity to help meet Nigeria’s growing demand, particularly in the gas to power sector. A major step forward in this respect has been the modular build-up of processing capacity at the Oben facility to create a strategic gas hub ideally located to aggregate and supply gas to Nigeria’s main demand centres.

Background

OML 4 covers an area of 267km2 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 bopd capacity flow station, a 465 MMscfd capacity non-associated gas processing plant and an associated gas compressor station with three 10 MMscfd associated gas (‘AG’) compressors. 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. 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 next due for renewal on 30 June 2019.

OML 38 covers an area of 2,094km2 and is located 48km north of Warri, Delta State. There are currently three producing fields on the block, namely Amukpe, Okpohuru and Ovhor (which straddles OML 38 and OML 41). There are three further discoveries in OML 38: the Mosogar, Orogho and Jesse discoveries, which have not yet been brought into production. Facilities on the block include a 45,000 bpd capacity flow station, a Liquid Treatment Facility (‘LTF’) and two 50,000 bbls crude storage tanks, all located at Amukpe. The licence was renewed in 1989 for a further 30 years and is next due for renewal on 30 June 2019.

OML 41 covers an area of 291km2 and is located 50km from Warri, Delta State. There are currently three producing fields on the block, namely Sapele, Sapele Shallow and Ovhor (which straddles OML 41 and OML 38), and two discoveries with contingent resources, the Ubaleme and Okoporo discoveries. Facilities on the block include a flow station with 60,000 bpd capacity, a 60 MMscfd capacity non associated gas processing plant and a 26 MMscfd NGC owned gas 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 and is next due for renewal on 30 June 2019.
