Nigerian oil tycoon Onajite Okoloko has stepped down as Chairman of Eroton Exploration & Production (E&P), marking the end of a transformative era for the independent oil company. His departure comes as part of a sweeping board restructuring led by James Ibori, a key political and business figure in Nigeria. This shift signals a new strategic direction for Eroton, one of Nigeria’s most prominent indigenous oil players.
Taking over the helm is Henry Imasekha, a seasoned chartered accountant and banking executive with a wealth of experience in corporate finance. His leadership is expected to bring financial discipline and strategic oversight as Eroton navigates ongoing industry challenges. The board shake-up, heavily influenced by Ibori, represents a concerted effort to restructure governance, stabilize operations, and strengthen Eroton’s position in Nigeria’s competitive upstream oil sector.
Onajite Okoloko’s Legacy in the Oil & Gas Industry
With over two decades in leadership roles across multiple energy and industrial ventures, Onajite Okoloko has played a pivotal role in shaping Nigeria’s oil and gas landscape.
His career began as a founding member of Ocean and Oil (now Oando Group) before he went on to establish Midwestern Oil & Gas, one of Nigeria’s most successful indigenous oil companies. Under his leadership, Midwestern secured the Umusadege oil field in the 2002 Marginal Field Bid Round, achieving a peak production of over 30,000 barrels per day.
At Eroton, Okoloko spearheaded one of Nigeria’s most significant oil transactions—the $1 billion acquisition of a 45% stake in Oil Mining Lease (OML) 18 from Shell, TOTAL, and Agip in 2015. This deal transformed Eroton into a major independent oil producer, reinforcing the growing dominance of indigenous firms in Nigeria’s energy sector.
Beyond oil, Okoloko made a significant mark in Nigeria’s industrial sector. As CEO of Notore Chemical Industries (2005–2021), he led the acquisition of NAFCON for $152 million and secured a landmark $222 million loan syndication from Nigerian banks. Under his stewardship, Notore became a key player in Nigeria’s fertilizer and agricultural value chain.
His influence extended to national policy, having served on Nigeria’s Presidential Committee on Oil & Gas (2004–2005), helping shape the country’s energy policies.
With an impressive track record in sales, marketing, and business development spanning over 25 years, Okoloko remains a key figure in Nigeria’s energy and industrial sectors.
The Future of Eroton Under New Leadership
Founded in 2013, Eroton was established to capitalize on asset divestments by major international oil companies (IOCs) seeking to reduce their presence in Nigeria. Its $1 billion acquisition of OML 18 in 2015 was largely financed through Midwestern Oil & Gas, a company partially owned by the Delta State government.
With Henry Imasekha now leading the board, Eroton is expected to undergo financial restructuring and operational stabilization. As part of this transition, Midwestern Oil & Gas has appointed Oboden Ibru as CEO, while Emeka Onyeka will serve as Acting CEO and Executive Director (Technical) at Eroton.
Eroton’s new leadership team faces several key challenges, including:
•Sustaining production at OML 18 amid industry shifts
•Meeting financial obligations and restructuring debts
•Strengthening governance and operational efficiency
•Maintaining competitiveness in Nigeria’s evolving oil sector
With James Ibori’s influence shaping the boardroom dynamics, the company appears to be gearing up for a new phase of strategic realignment.
A New Era for Eroton
Onajite Okoloko’s exit marks the end of an era for Eroton and signals the beginning of a new strategic direction. Under his leadership, the company made bold moves that positioned it as a formidable player in Nigeria’s oil and gas industry. However, with new leadership under Henry Imasekha and the oversight of James Ibori, Eroton now stands at a critical inflection point.
The coming months will be crucial as the company seeks to consolidate its position, restructure its operations, and navigate the evolving energy landscape in Nigeria. Whether this transition leads to sustained growth or further challenges remains to be seen, but one thing is certain—Eroton is entering a defining chapter in its corporate journey.
