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.”

OPEC Crude Output Falls to 37-Year Low Amid Iran Disruptions
By Adedapo Adesanya
Crude production under the collective Organisation of the Petroleum Exporting Countries (OPEC ) fell in May to its lowest level in at least 37 years as the blockade of Iran by the United States and disruptions in the Persian Gulf, continued to limit output.
According to a Bloomberg survey released on Friday, output from the organisation’s 11 current members, including Nigeria, dropped by 1.22 million barrels per day to 16.33 million barrels per day last month.
Iran accounted for more than half of the decline. The data excludes the United Arab Emirates (UAE), which departed the cartel last month after six decades of membership.
War between a US-Israeli alliance and Iran has reduced oil supplies from the Middle East, largely closing the Strait of Hormuz waterway. Saudi Arabia, Iraq, the UAE and Kuwait have been forced to cut crude production. Iranian shipments face additional pressure following a US blockade of its ports imposed in mid-April.
Iranian output fell by 710,000 barrels per day to a five-year low of 2.34 million barrels per day in May, the survey showed. Central Command reported that US forces have redirected 127 commercial vessels to enforce the blockade of all maritime traffic entering and exiting Iranian ports.
Kuwait recorded the second-largest decline last month, with production falling by 310,000 barrels per day to 490,000 barrels per day, less than one-fifth of pre-war levels. Saudi Arabia, the group’s leader, saw output decrease by 240,000 barrels per day to 6.57 million barrels per day.
The production reductions have not prevented OPEC and its allies from raising quotas over recent months, continuing a year-long process of restoring output halted several years ago.
This comes ahead of a meeting scheduled to be held on Sunday, June 7, where a sub-group of seven members is expected to increase targets by 188,000 barrels again in July. The session is one of four online meetings OPEC and its partners plan to hold that day.
Delegates indicated the alliance has plans for two additional monthly quota increases in August and September. UAE output rose by 300,000 barrels per day to 2.44 million barrels per day in May, according to the survey.

Debt Repayments: FG Overshoots Budget Allocation by 18%
By Aduragbemi Omiyale
The 2025 third quarter Budget Implementation Report from the Budget Office of the Federation has shown that the federal government exceeded the funds allocation for repayment of debts for the first nine months of the fiscal year by about 18 per cent.
In a report by Punch, the sum of N10.74 trillion was budgeted for debt servicing between January and September 2025, but the government used N12.63 trillion for the purpose, N1.90 trillion or 17.65 per cent more than the allocation for the year.
The funds were spent on domestic debts, foreign debts and sinking fund by the central government in nine months.
Business Post reports that for the whole year, the amount approved by the National Assembly and signed by President Bola Tinubu for debt repayments was N14.31 trillion.
Looking at the nine-month figures, domestic debt service gulped N6.23 trillion, exceeding its N5.39 trillion provision, while foreign debt service was N6.30 trillion versus the budget provision of N5.06 trillion.
According to the report, the figures indicated that 67.2 per cent of the federal government’s retained revenue of N18.63 trillion was spent on debt service in the first nine months of 2025. When the sinking fund is included, debt-related payments consumed about 67.8 per cent of revenue.
It was also observed that aggregate federal government revenue underperformed the budget by N12.03 trillion or 39.24 per cent, as actual revenue of N18.63 trillion fell short of the N30.67 trillion projected for the first three quarters.
In the third quarter alone, the government generated N7.70 trillion versus the quarterly target of N10.22 trillion as a result of persistent oil revenue shortfalls, despite stronger non-oil collections.
The debt burden also crowded out capital spending, as total capital expenditure was N3.10 trillion in the first nine months compared with the N17.58 trillion budgeted for the period, indicating that actual debt-related payments were more than four times capital expenditure.

Food Concepts Plc declined by 25 Kobo to trade at N2.50 per share versus the previous day’s N3.00 per share, and Acorn Petroleum Plc crumbled by 2 Kobo to end at N1.32 per unit, in contrast to the preceding session’s N1.34 per unit.
For the gainers, Central Securities Clearing System (CSCS) Plc added N2.93 to close at N78.34 per share compared with the previous price of N75.41 per share, and Afriland Properties Plc gained 80 Kobo to settle at N16.80 per unit versus N16.00 per unit.
There was a slip in the volume of transactions yesterday by 46.8 per cent to 280,714 units from 527,221 units, as the value of trades dropped 66.5 per cent to N21.8 million from the preceding session’s N64.2 million, and the number of deals fell by 8.7 per cent to 42 deals from 46 deals.
Great Nigeria Insurance (GNI) Plc ended the session as the most traded stock by value on a year-to-date basis with 3.4 billion units worth N8.4 billion, followed by Infrastructure Credit Guarantee (Infracredit) Plc with 2.3 billion units sold for N6.5 billion, and CSCS Plc with 64.7 million units traded for N4.4 billion.
GNI Plc also finished the day as the most traded stock by volume on a year-to-date basis with 3.4 billion units valued at N8.4 billion, followed by Infracredit Plc with 2.3 billion units exchanged for N6.5 billion, and Resourcery Plc with 1.1 billion units transacted for N415.7 million.
