Nembe Oil Spill: Expert Wants Preservation of Failed Wellhead for Analysis
By Adedapo Adesanya
An American university professor, Rick Steiner, has said between 532,000 and 1,064,000 barrels of crude oil has been spilt in the Nembe Oil Mining Lease (OML) 29 blowout, making the blowout one of the largest in world history.
Mr Steiner in a letter to the Nigerian National Petroleum Corporation (NNPC) Limited advised that the failed wellhead of the Nembe oil spill should be preserved for independent engineering forensic analysis to determine the cause of failure.
The professor, who is the Technical Advisor to the Ijaw Diaspora Council, said the failed wellhead should be assessed by either the US offshore oil regulatory agency, the Bureau of Safety and Environmental Enforcement (BSEE) and or Det Norsk Veritas (DNV) in Norway.
He maintained that the Nembe spill was much larger than government and industry statements suggest to date, and it would be prudent to correct those estimates.
“I understand that the Nembe OML 29 blowout may have been killed as of December 8, 2021, and as Technical Advisor to the Ijaw Diaspora Council, I wanted to provide you with my estimate of total discharge.
“If we assume 1-2 cubic feet of discharge per second (a very reasonable assumption), and that the blowout first occurred on November 1 (as reported by the Nembe communities), then the release lasted for a total of 38 days. This would have released a total of 532,000 barrels – 1,064,000 barrels of oil and gas, making the Nembe OML 29 blowout one of the largest in world history.
“Now that the blowout has apparently been killed, I urge you to preserve the failed wellhead for independent engineering forensic analysis to determine the cause of failure. The wellhead must be preserved as evidence, in standard criminal evidentiary procedures, to prevent any further alteration or adulteration, and then submitted to independent assessment.
“The people of Nigeria clearly deserve an independent assessment of what caused this catastrophic failure, and this is essential in preventing a repeat of this catastrophic failure in the future.
“I encourage the failed wellhead infrastructure to be assessed by either the U.S. offshore oil regulatory agency – the Bureau of Safety and Environmental Enforcement (BSEE) and/or Det Norsk Veritas (DNV) in Norway.
“Absent of a rigorous chain-of-custody, evidentiary preservation process for the failed equipment, and independent forensic evaluation, the true cause of the failure will never be conclusively determined.”
The university don regretted that the oil industry and government have been in the negative habit of underestimating oil spill volume, as was clearly seen in the 2010 United States’ deepwater horizon.
“A good example of the industry/government habit to underestimate spill volume was the 2010 Deepwater Horizon here in the U.S. BP and the US government first stated the flow rate from the failed seabed wellhead was 1,000 – 5,000 bbls/ day, and they clung to that estimate for some time (even though their internal engineers, and we, told them the flow was much higher).
“When an exact measure was finally conducted, using Particle Image Velocimetry and other engineering methodologies (by the Flow Rate Technical Group), the Macondo blowout outflow was put at 62,000 bbls/day. Again, this seems to always happen with spill volume estimates.”

The Central Securities Clearing System (CSCS) Plc has declared the first interim dividend in its history after posting its financial results for the first half of 2026, reflecting robust earnings growth, improved operating efficiency and stronger capital market activity.
The board approved an interim dividend of N1.00 per ordinary share for the six months ended June 30, 2026, citing the company’s strong cash generation, resilient balance sheet and confidence in the sustainability of its earnings.
The interim payout represents about 56 per cent of the total dividend of N1.78 per share paid for the 2025 financial year, underscoring its strong earnings momentum while preserving financial flexibility to invest in technology, innovation and future growth.
CSCS recorded one of the strongest financial performances in its history during the review period, with total operating income rising by 92 per cent to N18.51 billion from the corresponding period of 2025.
The growth was driven by higher transaction fee income as capital market activity strengthened, continued expansion in depository services, increased collateral management revenues and stronger contributions from data and technology-enabled services. Investment income also improved as the company optimised its investment portfolio.
Despite the sharp rise in revenue, operating expenses increased by only 38 per cent, reflecting disciplined cost management and the scalability of the company’s business model.
As a result, operating profit surged by 186 per cent to N10.11 billion, while profit before tax climbed by 115 per cent to N13.21 billion. Earnings per share also rose significantly to 190.1 kobo from 109.1 kobo in the corresponding period of 2025.
The organisation also recorded improvements in operating efficiency. Its cost-to-income ratio declined to 45.4 per cent from 63.2 per cent a year earlier, while operating profit margin improved to 54.6 per cent from 36.8 per cent.
According to the company, the results demonstrate not only the benefits of stronger market activity but also the resilience of its operating model and its ability to convert revenue growth into higher profitability, improved shareholder returns and sustainable long-term value creation.
Commenting on the interim dividend, the Chairman of CSCS Plc, Mr Temi Popoola, said the board’s decision reflected confidence in the firm’s financial strength, earnings quality and long-term strategic direction.
He said the strong performance was driven not only by increased market activity but also by sustained improvements in operational efficiency, disciplined cost management and the continued diversification of revenue streams.
Mr Popoola noted that the Board remained committed to balancing shareholder returns with investments in technology, innovation, resilience and new growth opportunities that would strengthen CSCS’ position as Nigeria’s leading financial market infrastructure and one of Africa’s foremost post-trade institutions.
The chief executive of CSCS Plc, Mr Shehu Yahaya Shantali, attributed the strong performance to the resilience of the entity’s business model, the dedication of its workforce and the confidence of market participants.
He said the first-ever interim dividend demonstrated the company’s ability to translate strong earnings growth and improved operating efficiency into enhanced shareholder value.
Mr Shantali added that CSCS would continue to strengthen its core market infrastructure, invest in technology and innovation, diversify its revenue base and enhance value creation for stakeholders while supporting the development of Nigeria’s capital market.

The Ministry of Solid Minerals Development and the National Identity Management Commission (NIMC) have strengthened their partnership to deploy digital identity technology, aiming to combat illegal mining and enhance security in Nigeria’s mining sector.
Speaking while receiving the Director-General and management of NIMC on a courtesy visit to his office in Abuja, the Minister of Solid Minerals Development, Mr Dele Alake, described the commission as a critical institution in Nigeria’s development architecture, stressing that effective governance could not be achieved without a credible identity management system.
“NIMC occupies a critical position in translating policy into reality. It is pivotal to the development of any nation because governance today is driven by data, technology and credible identity systems,” he added.
He noted that inadequate identification systems had weakened enforcement efforts over the years, allowing illegal mining activities to flourish in mineral-rich communities.
“Without identification, we cannot trace or track, and insecurity will flourish. In the solid minerals sector, we need effective monitoring of both legal and illegal operations.
“A credible identity ecosystem will strengthen regulation, improve enforcement and support our efforts to sanitise the sector,” Mr Alake said.
The minister identified technology, statistics, data gathering and digital identity as critical enablers for evidence-based policymaking, improved regulatory oversight, efficient licensing, investment promotion and national development.
On her part, the DG of NIMC, Mrs Abisoye Coker-Odusote, highlighted several opportunities for collaboration between both institutions, noting that the newly enacted NIMC Act has positioned Nigeria to fully embrace a digital governance ecosystem.
She explained that deeper integration of identity management into the solid minerals sector would facilitate database integration across government institutions, enhance regulatory compliance, strengthen security and law enforcement, improve monitoring of operators, and provide stronger support for the implementation of Community Development Agreements (CDAs) in mining host communities.
Mrs Coker-Odusote added that NIMC’s upgraded digital infrastructure is capable of supporting government institutions in building reliable databases, improving transparency and delivering more efficient public services.
Both institutions said they would immediately begin implementing technology-driven initiatives under the partnership, expressing confidence that expanding access to trusted digital identities for miners and other eligible residents would enhance accountability and strengthen governance in the solid minerals sector.
