Nembe Oil Spill: Expert Wants Preservation of Failed Wellhead for Analysis

Nembe Oil Spill

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.”

CPPE Projects Naira Stability in Q2, Flags Volatility Risks

Published

The Centre for the Promotion of Private Enterprise (CPPE) has projected relative stability for the Naira exchange rate in the second quarter of the year, supported by improved foreign reserves and liquidity, but cautioned that volatility risks remain.

In its Q1 2026 Economic Review and Q2 Outlook: Macro Stability Gains Amid Persistent Cost Pressures and Rising Geopolitical Risks report released on Sunday, the think-tank’s chief executive, Mr Muda Yusuf, said exchange rate conditions also improved significantly as the Naira, which experienced substantial volatility during the reform transition period, stabilised within a relatively narrow band of about N1,340–N1,430 per Dollar in the official market during Q1 2026.

“This stability has helped to moderate imported inflation and restore a measure of business confidence. External reserves strengthened considerably, rising above $50 billion in early 2026,” he stated.

The group said that the Nigerian economy in the first quarter of 2026 reflected a blend of improving macroeconomic stability and persistent structural constraints.

It said that proof of a more stable macroeconomic environment is increasingly evident, underpinned by the cumulative gains from foreign exchange reforms, a sustained period of monetary tightening, and the gradual normalisation of key economic indicators.

However, it noted that these improvements continue to coexist with significant headwinds, adding that the country’s economic growth will remain positive in the next three months, but the pace of expansion may slow due to mounting downside risk

The report also warned of a growing risk of stagflation, as persistent cost pressures combine with fragile growth conditions. It added that rising political activities ahead of the 2027 general elections could weaken reform momentum and distract from economic management.

The CPPE noted that rising global crude oil prices, triggered by the ongoing Middle East conflict, pose a major threat to Nigeria’s fragile disinflation process. While higher oil prices could boost export earnings and government revenue, the think tank stressed that the domestic impact would be adverse.

“The cost pass-through effect poses a significant threat to the fragile disinflation process, potentially reversing recent gains in price stability, weakening real incomes, and further exacerbating the cost-of-living pressures facing households and businesses,” the organisation said.

Highlighting monetary policy concerns, CPPE said the current inflationary trend is largely driven by structural and cost-related factors rather than excess demand, observing that, “Additional monetary tightening would have limited effectiveness in addressing the underlying drivers of inflation, while potentially exacerbating constraints on investment, credit expansion, and overall economic growth.”

The CPPE further raised concerns over the implementation of the proposed N68 trillion 2026 budget, citing weak revenue performance, delays in capital releases, and growing political influence on spending priorities.

“As political pressures intensify, there is a risk of weakening fiscal discipline, with greater emphasis on recurrent and politically expedient spending,” the group stated, advising businesses to shift focus towards resilience and efficiency, urging firms to prioritise cost containment, adopt alternative energy sources, and strengthen foreign exchange risk management strategies.

It also called on policymakers to take urgent steps to safeguard economic stability and protect vulnerable groups.

“Policy priorities should therefore focus on consolidating macroeconomic stability, addressing structural bottlenecks, and implementing targeted measures to protect vulnerable populations,” it noted.

The CPPE concluded that while macroeconomic stability gains recorded in the first quarter of 2026 are notable, the outlook for the second quarter remains cautiously positive but increasingly uncertain due to geopolitical tensions, fiscal risks, and domestic political dynamics.

OPEC+ Boost Output by 206kb/d as Iran War Limits Production

opec oil output

By Adedapo Adesanya

The Organisation of the Petroleum Exporting Countries and its allies (OPEC+) agreed to raise its oil output quotas by 206,000 barrels per day for May.

Eight members of ​OPEC+, comprising Saudi Arabia, Russia, Iraq, the UAE, Kuwait, Kazakhstan, Algeria, and Oman, agreed to the increase in May quota at a virtual meeting on Sunday, OPEC+ said in a statement.

However, the rise will be in theory, as its key members are unable to raise production due to the US-Israeli war with Iran, which has affected production.

The war has effectively shut the Strait of Hormuz, the world’s most important oil route, since the end of February and cut ​exports from some OPEC+ members, including Saudi Arabia, the UAE, Kuwait and Iraq. These are the only countries in the group which were able to significantly raise ​production even before the conflict began.

Besides the disruptions affecting Gulf members, others, ​such as Russia, are unable to increase output due to Western sanctions and damage to infrastructure inflicted during the war with Ukraine. For Nigeria, even as Africa’s largest producer, it has not been able to keep production quotas steady.

The OPEC+ quota increase of 206,000 barrels per day ​represents less than 2 per cent of the supply disrupted by the Hormuz closure, but it signals readiness to raise output once the waterway reopens.

Also meeting on Sunday, a separate OPEC+ panel called the Joint Ministerial Monitoring Committee (JMMC), expressed concern about attacks on energy assets, saying they were expensive and time-consuming to repair and so have an impact on supply.

May’s OPEC+ increase is the ​same as the eight members had agreed for April at their last meeting held on March 1, just as the ​war began to disrupt ⁠oil flows.

A month later, the largest oil supply disruption on record is estimated to have removed as many as 12 to 15 million barrels per day or up to 15 per cent of global supply.

The eight OPEC+ members have raised production quotas by about 2.9 million barrels per day from April 2025 through December 2025, before pausing increases for January to ​March 2026. The sub-group holds its next meeting on May 3.

Market analysts have warned that oil prices could hit $150 per barrel if the closure of the strait is prolonged and continues, due to damage to energy assets across the critical Middle East region.

As of the time of this report, Brent crude is trading at $108 per barrel, below the US West Texas Intermediate (WTI) crude at $109 per barrel.

Seplat Operations Resume After Pay Rise Deal With Striking Workers

Seplat Energy

By Adedapo Adesanya

Workers at Seplat Energy will resume work after a strike action that impacted production was called off by the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) over the weekend, with the company issuing written commitments ‌on pay rises.

Top employees began an indefinite strike last Friday as talks over a collective bargaining agreement and staff ​welfare issues broke down. The action came at a time when Nigeria is ​seeking to maximise production amid rising global oil ⁠prices.

According to Reuters, in an April 4 letter to the chief executive of Seplat Nigeria, Mr Roger Brown, PENGASSAN said it had directed members at the local energy firm to immediately suspend industrial action after negotiations resumed with ​the Nigerian National Petroleum Company (NNPC) Limited. Other less-skilled workers are covered by the Nigeria Labour Congress (NLC) and did not partake in the strike with PENGASSAN.

The union said ​talks on a 2026 collective bargaining agreement would continue, with the ‌aim ⁠of concluding outstanding issues by April 13. However, according to the publication, the union did not disclose more details about its financial demands.

“We can confirm that the union has suspended its notice ​of industrial action ​to allow ⁠negotiations to conclude on outstanding items within an agreed framework,” Seplat spokesperson, Mr Ogechukwu Udeagha, ​said, adding that “operations are recommencing at our various locations.”

Seplat Energy’s group production averaged 131,506 ​barrels of oil ​equivalent per ⁠day in 2025, according to its latest audited results. That is the equivalent of around ​7 per cent–9 per cent of Nigeria’s total liquids production.

The company expects ​output ⁠to rise to 155,000 barrels of oil ​equivalent per ⁠day, making any sustained disruption particularly sensitive for Nigeria’s supply outlook. This comes as it seeks to ​scale production while remaining a major supplier of gas to Nigeria’s ​domestic power market.

With the company’s output expected to rise, any prolonged disruption would have significantly impacted Nigeria’s oil supply and fiscal outlook.
