Seplat Energy Plc is entering a new phase of expansion as the Nigerian energy company moves to strengthen its position as one of Africa’s leading indigenous oil and gas producers.

The company has appointed Engr. Effiong “Effy” Okon as Chief Executive Officer and Executive Director, while business leader Tony O. Elumelu, CFR, takes over as Chairman of the Board.

The leadership transition comes as African energy markets undergo a major transformation, with international oil companies reducing exposure to some onshore and shallow-water assets and indigenous operators increasingly taking a larger role in production, infrastructure development and energy security.

For investors and global energy markets, Seplat’s leadership restructuring signals an ambition to evolve beyond a local independent producer into a major African energy company with the capabilities of an international operator.

Okon brings more than three decades of technical and operational experience in the global oil and gas industry, including over 26 years with Shell plc, where he held senior technical and leadership roles across major international assets.

His experience includes managing reservoir and production operations at Qatar’s North Field, widely regarded as one of the world’s largest natural gas reserves, as well as leadership roles linked to major gas and deepwater projects.

He also served as General Manager of Deepwater Production at Shell Nigeria, overseeing operations at the Bonga field, one of Nigeria’s most significant deepwater assets.

Analysts say Okon’s engineering background and experience in cost optimisation could prove critical as energy companies navigate higher operating costs, regulatory changes and the evolving global transition agenda.

A key part of his recent track record was his leadership role at the ANOH Gas Processing Company (AGPC), a joint venture involving Seplat Energy and NNPC Limited.

The project achieved first gas production in 2026, strengthening expectations that indigenous companies can successfully deliver large-scale energy infrastructure projects.

The development is particularly significant for Nigeria, where expanding domestic gas supply remains central to improving electricity generation, industrial growth and energy security.

The appointment of Tony Elumelu as Chairman adds further strategic weight to Seplat’s next growth phase. Through Heirs Holdings, Elumelu holds a major stake in the company and has promoted long-term private-sector investment across Africa.

The combination of Elumelu’s investment leadership and Okon’s technical expertise is expected to support Seplat’s strategy to expand its upstream operations, grow its gas business and attract international capital.

Industry observers say the company’s next challenge will be execution — delivering production growth, maintaining operational efficiency and competing in a global market where energy security and the transition to lower-carbon systems are reshaping investment decisions.

With its Roadmap 2030 strategy, Seplat aims to strengthen its position as a leading African energy company capable of managing large-scale assets while supporting the continent’s industrial development.

The leadership transition represents a broader shift in Africa’s energy sector, where indigenous firms are increasingly moving from asset ownership to becoming full-scale operators with global ambitions.
