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.”

Trump’s Tariff: Alake Woos Investors to Nigeria’s Solid Minerals Sector

By Adedapo Adesanya
The Minister of Solid Minerals Development, Mr Dele Alake, has called on foreign investors to consider Nigeria amid prevailing barrage of tariffs imposed by the United States, which he says may be a blessing in disguise for African countries.
Speaking during the Fireside Chat session on Foreign Direct Investment in Abu Dhabi, United Arab Emirates, the Minister called on African countries to adopt an introspective approach by looking inward and adjusting their domestic policies to focus more on intra-African trade, with less dependence on external forces.
In a statement by his Special Assistant on Media, Mr Segun Tomori, on Sunday in Abuja, it was stated that the Minister’s remarks were part of his contribution to the discourse on the impact of the tariffs on Africa’s economic climate.
“The barrage of tariffs imposed carries wide-ranging implications for the global economy, U.S. trade relationships, and developing nations, including those in Africa,” he said.
He stressed the need need for African countries to organise economic imperatives to ensure a balance of trade and strengthen intra African trade among countries.
Mr Alake highlighted the persistent challenge faced by African countries, where rare mineral resources were exported without any value addition, noting that the old ‘pit-to-port’ model, where resources are extracted and sent out of the continent can no longer be allowed to continue.
“Interested investors, who wish to come into Africa are welcome to set up their factories in the continent, add value to our mineral resources and create jobs here, rather than just shipping our wealth out of our shores”, he stated.
The minister said that his stance on protecting Africa’s mineral wealth has been adopted by many African countries, particularly mineral-producing nations, where he served as the pioneering chairman of the African Minerals Strategic Group (AMSG).
He reaffirmed that Nigeria’s policy on mineral sector development remained strictly focused on value addition and boosting the local economy through job creation.

Arnergy Raises $18m to Boost Solar Energy Access in Nigeria

By Adedapo Adesanya
Arnergy, a cleantech startup, has raised a $15 million Series B extension, on top of a $3 million B1 round last year, bringing its total for the round to $18 million to boost solar energy access in Nigeria.
According to TechCrunch, the new funding round was led by Nigerian private equity firm CardinalStone Capital Advisers (CCA) and saw participation from Breakthrough Energy Ventures as well as British International Investment, Norfund, EDFI MC, and All On.
Launched in 2013, Arnergy was established to provide solar systems to homes and businesses across sectors like hospitality, education, finance, agriculture, and healthcare.
The firm raised a $9 million Series A in 2019 backed by Bill Gates’s Breakthrough Energy Ventures.
The Lagos-based cleantech is in talks to raise additional local debt from banks and development financial institutions (DFIs) to support some of its projects including energy-as-a-service (EaaS) solutions for multinationals.
The cleantech is planning to install more than 12,000 systems by 2029 to help boost access to solar energy, which Nigerians have began to adopt increasingly following policy shifts, particularly the removal of fuel subsidies, that led to rise in energy costs.
Arnergy has so far deployed over 1,800 systems across 35 Nigerian states, totaling 9MWp of solar and 23MWh of battery storage.
Over the next four years, it will be targeting a 567 per cent increase to the set 12,000 systems goal.
According to the founder, Mr Femi Adeyemo, there has been increased adaptation of solar energy and this presents the perfect opportunity.
Its lease-to-own product, Z Lite, has gained more traction as customers pay fixed monthly fees over 5 to 10 years before owning the system while outright purchases comprised 60 per cent to 70 per cent of revenue in 2023, accounting for just 25 per cent of sales last year, as per TechCrunch.
“Imagine paying N200,000 (~$125) every month for power. With our product, that drops to N96,000 (~$60). Over five years, it’s a no-brainer what you’ll save,” Mr Adeyemo told the tech publication.
Recall that the federal government has also announced plans to ban importation of solar panels as part of efforts to boost local capacity. This has been projected to see a substantial increase in prices.
Speaking on this, Mr Adeyemo said, “We’re advocates for local manufacturing. But let’s build capacity before shutting the door on imports. Otherwise, we risk doing more harm than good, both to the industry and to the millions of Nigerians who now rely on solar as their primary energy source.”
