Driven by its African identity, Nigerian independent Heirs Energies operates with an in-house development approach, partnering largely with indigenous contractors

Following its inspiring success story with OML 17, the company is ready to take on further challenging projects, now eyeing the Republic of Congo. 

Heirs Energies CEO, Osa Ighiehon, reveals to Oil Review Africa what it takes to thrive as an African independent in today's energy industry and much more: 

What according to you does Nigeria’s oil and gas industry need right now to attain its full potential? 

Nigeria is at a critical moment. We possess the resources and the human capital to be a global energy leader, yet we are constrained by a few critical but addressable challenges. To unlock our full potential, we must act decisively on three fronts.

First, we must establish unwavering policy certainty. The lifeblood of our industry is investment, and capital flows to jurisdictions that offer predictability and stability. We need a clear, consistent, and transparent regulatory framework, one where fiscal term are stable and approvals are streamlined. Without this foundational trust, we risk ceding competitive advantage and watching investment capital migrate to more predictable markets. There has been a lot of progress on this front in the past few years with the Petroleum Industry Act (PIA) and Presidential Directives.

Secondly, we must secure our infrastructure and consolidate the gains we've made. The scourge of oil theft has been a direct drain on our national treasury. However, the solution that has been deployed needs to be sustained and the threat/vulnerabilities permanently mitigated. As demonstrated with OML 17, where we moved from a 3% terminal delivery to over 99%, it is possible to secure assets through a collaborative model that integrates community engagement, corporate strategy, and crucially, the strengthened security framework provided by the government. This proven model must now be scaled nationally to protect our vital revenue streams and restore investor confidence.

Lastly, and most critically, we must execute a strategic pivot to gas. While oil built our economy, gas is the undeniable key to our future. Sitting on the largest proven gas reserves in Africa, it is an economic paradox that we remain dependent on imported fuels. Gas is the catalyst that will power our industries, generate stable electricity, and drive sustainable economic diversification. At Heirs Energies, we have moved from rhetoric to action, increasing our gas production from 70 mn standard cu/ft to 125 mn standard cu/ft. This is not merely a business decision; it is a national imperative. By prioritising gas, we can finally unlock a new era of industrialisation and long-term prosperity for Nigeria.

While digitalisation is largely being considered the key to production optimisation, do you believe it’s the sole requisite to success? 

Digital tools are important, but they are not a magic fix. Technology helps us work smarter, but it can't replace the need for strong leadership and skilled people.

We use technology at Heirs Energies for monitoring and efficiency. But our biggest breakthroughs have come from our teams. For example, our engineers developed a low-cost way to bring old gas wells back to life. That idea didn't come from a software programme; it came from deep understanding, out-of-the-box thinking and a solution mindset.

While digitalisation gives us better data, our success finally depends on our people - their expertise, ingenuity and commitment to safety. Its this human element that truly makes the most difference.

What is Heirs Energies’ future strategy with OML 17 and other oil and gas assets? 

Our strategy is to build on the proof point that OML 17 represents. When we acquired it, many doubted whether a Nigerian independent could revive such a complex, underperforming asset. Today, we have doubled production, restored security, and brought new energy to the domestic gas market. That success gives us the confidence to look ahead with intent.

At OML 17, we are determined to keep pushing performance higher - optimising oil output, scaling gas production further, and embedding the community partnerships that have become a hallmark of our approach. But the bigger picture goes beyond one asset, we see opportunities across Nigeria and Africa to apply our Brownfield Excellence model - identifying underperforming fields, deploying innovation and discipline, and turning them into engines of growth.

What matters to us is creating long-term value for our investors, for the communities where we operate, and for the economies that depend on reliable energy. That means expanding carefully, investing responsibly, and ensuring that every molecule we produce helps to power Africa’s development. OML 17 was the beginning - but our ambition is to shape the model of how African companies can deliver world-class results and shared prosperity, consistently and at scale.

As Eni's Coral South project effectively continues to be in production, the major has now reached the final investment decision (FID) for the development of the Coral North FLNG project in Mozambique, with an aim for project delivery by 2028 

The agreement was signed in Maputo by the Eni-led joint venture behind the project, in the presence of the President of Mozambique, Daniel Francisco Chapo, and Eni CEO, Claudio Descalzi. 

While Eni is leading the venture with a 50% share, other partners include CNPC (20%), Kogas (10%), ENH (10%) and ADNOC-subsidiary XRG (10%). Eni will be investing on the development of a state-of-the-art floating LNG facility in the Rovuma Basin, where it will be generating gas volumes from the northern part of Area’s 4 Coral gas reservoir.

Eni CEO Claudio Descalzi commented: “Coral North project leverages Eni’s unmatched exploration skills, our trademark fast-track and capital disciplined development capabilities, Mozambique’s vast gas resources and its strategic geographic position. With Coral North we will contribute to supply the worldwide growing demand for LNG, doubling both Mozambique's contribution to global energy security, and the benefits for the country and its citizens in terms of economic and industrial growth”. 

Coral North will be Eni’s second development in Mozambique and the second large-scale FLNG delivered in ultra-deep waters worldwide after Coral South. 

With a production liquefaction capacity of 3.6MTPA, the newly built Coral North FLNG - coupled with its predecessor Coral South - will bring Mozambique’s overall LNG production to exceeding 7MTPA, making the country the third-largest LNG producer in Africa and further reinforcing its role in the global energy scenario.

This project underscores GTT’s central role in enabling major floating LNG developments in new markets.

GTT will be delivering the tank design of a new floating liquefied natural gas (FLNG) unit for Samsung Heavy Industries before it is ready for deployment in the African waters

The deal, which was made during the third quarter of 2025, will see GTT designing the cryogenic membrane containment system for the LNG storage tanks, with a total capacity of 238,700 cu/m. The tanks will be fitted with GTT’s Mark III technology.

This project underscores GTT’s central role in enabling major floating LNG developments in new markets and demonstrates how FLNG solutions can rapidly deliver offshore liquefaction capacity without relying on onshore infrastructure.

Philippe Berterottiere, chairman and CEO of GTT, said,“We are proud to contribute our unique expertise to this major FLNG project, which will help harness Africa’s energy potential to support sustainable growth and energy supply. This order confirms the trust of our long-standing partner Samsung Heavy Industries and demonstrates the relevance of GTT’s technologies to support the development of efficient, reliable and safe floating LNG infrastructure.” 

 

The Agogo project involves the development of Agogo and Ndungu fields.

The Agogo FPSO has generated first oil for the National Agency for Petroleum, Gas and Biofuels (ANPG) and Azule Energy, actualising the much anticipated Agogo Integrated West Hub project offshore Angola 

This comes in less than three years since the Agogo IWH project began in February 2023, with a phased development approach. It involved appraising-driven process, de-risking the full field exploitation. With a well-coordinated effort to simultaneously manage activities across reservoir, engineering and procurement, the deepwater project is said to have been achieved in record time. 

The Agogo project involves the development of two fields, Agogo and Ndungu, in the West Hub of Block 15/06. The Agogo IWH project operated by Azule Energy in Block 15/06, with a 36.84% stake alongside partners Sonangol E&P (36.84%) and Sinopec International (26.32%), is set to add substantial production to Angola's energy landscape. Together, the two fields have estimated reserves of approximately 450 million barrels, with projected peak production of 175,000 barrels per day, produced via two FPSOs (Agogo and Ngoma). 

An ode to technological innovation and lower-emissions future, all topsides and marine systems of the Agogo FPSO are designed to be fully electric. Touted as a 'green' FPSO, it features a pilot carbon capture and utilisation/storage (CCUS) unit to recover remaining CO2 volumes. Additionally, the FPSO benefits from combined cycle power generation.

"This new milestone that we have recorded in the Agogo Project reinforces our certainty that we have made the right investment in technological innovation and the valourisation of Angola's natural resources, in an industry where it is essential to combine sustainability, efficiency and inclusion procedures. It is worth highlighting that this is an FPSO prepared to reduce carbon emissions, aligning with energy transition objectives. Furthermore, it demonstrates a strong investment in national human capital, with 80% of the workforce comprised of Angolans,' said the chairman of the Board of Directors of ANPG, Paulino Jerónimo.

"The startup of the Agogo IWH project, sanctioned just months after Azule Energy's formation, represents a defining moment for our company," said Adriano Mongini, CEO of Azule Energy. "It demonstrates not only our technical capabilities but also our firm commitment to supporting Angola's energy landscape. This achievement advances our production goals whilst showcasing our dedication to responsible energy practices through pioneering emission reduction initiatives. We are immensely proud to contribute to Angola's energy future and to set new standards for environmental responsibility in offshore operations."

The agreement will considerably push Nigeria's deepwater development.

Exploration

As Oil Prospecting Licence 245 (OPL 245) undergoes conversion, the President of the Federal Republic of Nigeria, Bola Ahmed Tinubu, and Eni's chief executive officer, Claudio Descalzi, met in Abuja to explore how the development can advance the Nigerian deepwater sectors

A significant feature of the agreement is the discontinuation of the international arbitration proceeding at the International Centre for Settlement of Investment Disputes (ICSID), thus allowing the conversion of the existing license into two development licences, Petroleum Mining Leases (PML) 102 and 103, and two exploration licences, Petroleum Prospecting Leases (PPL) 2011 and 2012, to Nigerian Agip Exploration Limited (NAE) as operator, alongside its partners Nigerian National Petroleum Company Limited (NNPC) and Shell Nigeria Exploration and Production Company Limited (SNEPCO). 

The agreement will considerably push Nigeria's deepwater development with Eni set to apply its know-how on the Zabazaba and Etan fields for optimal output. An extensive programme has been devised to generate approximately 500 MMbbl of reserves from the fields, including the deployment of a 150 kbopd capacity FPSO processing facility, while gas (200 MMSCFD at peak) will be exported through Nigeria LNG. The highly potential PPL 2011 and PPL 2012 exploration licenses will also be developed in line with the Zabazaba and Etan fields for a well-synced operational and production output from all facilities involved.

President Tinubu and Mr Descalzi also discussed Eni’s significant investment portfolio — including the Abo and Bonga fields and Nigeria LNG — as well as on potential new developments designed to expand the country’s offshore production capacity. Within this framework, and in line with its long-term strategy in the country, Eni has recently expanded its interests in deep-water developments, with the acquisition of an additional stake in OML 118, now holding 15%.

Energy data and intelligence provider, TGS, has announced the Ultra Profundo multi-client 2D survey offshore Angola

The survey spans approximately 12,600 line kilometers, and Ramform Victory began operations earlier in Q1. Data acquisition is likely to be completed in around 100 days, with fast-track products available in Q3. Full data processing is scheduled for completion in Q2 2027.

The Ultra Profundo multi-client 2D survey marks the first 2D multi-client acquisition over Angola’s ultra deep-water areas since 2015 and aims to reach previously underexplored region. The survey delivers modern, long-offset seismic data critical for imaging complex pre-salt and top-salt structures as well as basin floor channel systems, significantly enhancing regional geological understanding.

Kristian Johansen, CEO of TGS, said, “Angola’s ultra deep-water margin represents one of the most exciting frontier exploration opportunities in West Africa. Our Ultra Profundo multi-client 2D program delivers high-quality seismic coverage needed to unlock pre-salt and sub-salt potential. By leveraging TGS’ acquisition and imaging capabilities, we will provide high-quality data supporting future exploration activities.”

TEN field's total production count for 2025 is 16.0 kbopd.

Technology

With all reservoir and operations risks for 2026 considered, Tullow Oil is aiming an average production rate of 34-42 kboepd, including 6 kboepd of gas 

In 2025, Ntomme and Enyenra performance from TEN led the field's total production count at 16.0 kbopd, while the exit rate from Jubilee stood at 57 kbopd. 

The company will be deploying riser system and riser-base gas lift for well production management activities, and waterflood and fluid lift optimisation. These, along with the support of high-uptime FPSO, five planned Jubilee wells (four producers and one water injector) are expected onstream this year. The J75-P, for instance -- where a rig has been active for drilling -- has recorded three good reservoir intervals. 

The recently completed J74-P well is already onstream since January, revealing 50 meters of net pay while generating an initial gross production through the wellbore at 13 kbopd. 

The well management measures align with findings from 4D seismic and Ocean Bottom Node seismic surveys to leverage significant reservoir information extracted. 

Tullow has made a strategic investment to acquire the TEN FPSO as it will simplify operational synergies between the TEN and Jubilee fields, maximising output in the long term with minimal expenses. The company has already secured 10-year and 14-year-long ratifications on the West Cape Three Points and Deep Water Tano Petroleum Agreements.

Ian Perks, chief executive officer, Tullow Oil Plc, said, “2025 has been a year of disciplined execution across the business. This includes strong operational momentum which continues with excellent results from the latest Jubilee well and a further five wells due onstream this year to support our production targets. We have achieved significant cost reductions and completed the sale of non-core assets in our ongoing efforts to streamline our portfolio and strengthen our financial position.

“However our 2025 full year free cashflow was negatively impacted by the commodity price environment towards the end of the year and delays in receipt of Government of Ghana receivables and the second instalment of proceeds from the Kenya disposal.

“The refinancing transaction we have announced today enables us to focus on delivering our near-term priorities, which include driving further cost efficiencies, improving cashflow management and optimising our production."

 

The panel's theme was 'Africa's energy transition on African terms'.

Gas

Crystol Energy's founder and chief executive officer, Dr. Carole Nakhle, moderated an Africa-focused panel during the recently concluded International Energy Week in London to get a perspective on the continent's stand on decarbonisation and energy transition practices

"It's not saying that decarbonisation should be ignored, but the truth is, you can't decarbonise what you don't have. If you don't have energy, you can't be talking about decarbonisation. You have to have the energy faster than you decarbonise," said the Nigerian National Petroleum Company's chief financial officer, Adedapo Segun, in the context of poor energy access in Africa

Segun's case was further supported by Renaissance Africa Energy Company's managing director and chief executive officer, Tony Attah, who said that with a teeming youth population, Africa cannot compromise on industrialisation. "I think it's a no brainer that from an African lens, from a Nigerian lens, industrialisation is what will move people out of poverty. We want to be given the flexibility to use the same resources to achieve what Europe and the rest of the world has achieved. From an African lens, it's survival first. I haven't survived. You're asking me to make a choice. It's about the industrialisation of Africa...when you talk about the whole emissions and impact on climate, data suggests that the entire Africa is contributing way less than 4% so essentially, we can even carry on at two, three times the scale today, and it will not be of any significant impact," Attah said.

While Dr. Nakhle was all ears, she stressed Africa's responsibility to eliminate flaring for sustainable production. "Just by increasing the penalty on gas flaring, you motivate the companies to actually still produce oil and gas with lower carbon intensity, because I think that would be the winning step for the future, and not to continue with what was a good old fashioned way of producing oil and gas."

According to Attah, flaring has been a focus area for most creditors as part of decarbonisation strategy, which aligns with attaining zero routine flare by 2030. With engineers working on projects to deal with gas storm compression infrastructure that are capable of moving gas from flood centres to the market, there has been a massive reduction in flare now. 

Gas is already driving Africa's energy narrative, with around 620 trillion standard cubic feet coming solely from Algeria, Mozambique and Nigeria. The world has come to Africa with massive investments, not just for international market but also the domestic market. The nation is hence way past the stage of "making a case", as now its just a matter of the investments unleashing the potential that is trapped in all these countries.

"Gas is going to be the game changer for us. So we are looking to develop our gas resources and export the gas to derive the financing for developing the country, and bridging the infrastructure gap," said AGPC's managing director, Effiong Okon, as he gave some perspective on Nigeria's national budget against the infrastructure budget of European countries.

"We have a budget of just about 20 something million dollars. That is for the whole country, and 45% of that goes to debt service. Another 15% goes to security. So you have 60% of the budget locked in debt service and security. And with that, you really cannot build infrastructure. You need to improve the standard of living. It becomes impossible. I checked on some of the European countries, Germany, for example, for just for infrastructure in 2026 [it is] going to spend close to US$200bn. So we really need to find the prosperity to develop," he said. 

Dr. Nakhle also raised the question of Africa's biggest paradox. "Africa is rich in energy resources, and yet it is poor when it comes to energy consumption. What do you think needs to change to change this reality on the ground?" she asked.

Attah's answer was that Africa is looking at a typically extractive industry when it comes to oil and gas. While the resource belongs to the nation, it was entirely under the control of international oil companies. Due to this structural dislocation, IOCs will extract, go and develop their respective countries with it. But now with majors announcing massive divestments on the back of onshore maturation, companies like Renaissance were feeling the heat. "But I have to thank NNPC for just supporting the divestment to go through. So we bought the share assets, and you can imagine that our philosophy and vision will be different from that of an IOC. We have a very audacious vision to be the African leader in energy. The IOC will not want to be the African leader in energy. They want to be the global leaders, but we want to be the African leader in energy. We want to enable energy security, [and] we want to bring about the industrialisation of Nigeria. Now that was not an assignment for the IOC...We are now taking our destinies in our hands to the extent that we will have no choice than to ensure that that shared prosperity from this energy resource base changes the narrative. On behalf of Nigerians, starting from Nigeria, pivoting to rest of Africa, which is why we like to say as Renaissance, we were made in Nigeria, built for Africa," he said. 

On the energy transition front, Silvia Macri, Middle East and Africa lead, Power & Renewables, S&P Global, said, "If you think about diversification, some countries in western Africa, Kenya in eastern Africa, are pushing either away from a fossil fuel heavy energy mix, or diversifying the sources, instead of having one major source of the produces, power or energy for the country; just choosing all the different options that are available. And this is something that South Africa, for example, has started doing at a faster pace. Kenya is probably the country where this has happened at the highest level, because it has a huge availability of geothermal resources, which allowed the diversification into renewables, but western African countries are bringing gas generation in the mix together with renewables...going forward, [it is important that] the decisions that they're making are more for the longer term, and they're not just solving the problem that is immediate."

 

 

Vitol Bahrain EC has a long-standing presence in Uganda's downstream sector.

Downstream

As the Uganda National Oil Company aims to build a crude refinery, it has reached out to a unit of global commodities trader, Vitol, for a US$2bn loan to support the project alongside construction and infrastructure developments

According to Henry Musasizi, Uganda's junior finance minister, this seven-year tenor loan from Vitol Bahrain EC (VBA) comes with an interest rate of 4.92%. The minister worked on advancing the approval process for the credit line and the loan, which involved significant lawmakers, who sanctioned the development with a majority verdict.

Musasizi said that Vitol's support "presents an opportunity to access non-traditional financing to implement. ..projects and support the government in developing national infrastructure."  

Vitol Bahrain EC has a long-standing presence in Uganda's downstream sector, functioning as the sole supplier of refined petroleum products to UNOC, before the state-owned company sells it to retailers across the country.

Alongside the refinery, the loan amount will also be covering road construction, a petroleum products storage terminal and extension of a petroleum pipeline from western Kenya to Uganda's capital Kampala.

Previously, the UNOC also concluded a deal with the UAE-based Alpha MBM Investments, whereby a domestic refinery with a capacity of 60,000 barrels per day is in the pipeline. The agreement accords 60% stake on the refinery to the UAE firm while UNOC retains 40%.

Uganda is looking to begin commercial oil generation starting next year from fields in its west.

Oil Review Africa catches up with Christopher Hudson, President of dmg events, ahead of ADIPEC 2025

Excerpts from an interview: 

Energy across Africa, as elsewhere in the world, is seeing major shifts and advancements. How does ADIPEC 2025 reflect this changing industry landscape and help meet the needs? 

Energy is one of the most dynamic and rapidly evolving sectors. According to the International Energy Agency (IEA), global energy demand rose by 2.2% last year, outpacing the average annual increase of 1.3% recorded over the last decade. At the same time, the global population is projected to reach 9.8 billion by 2050, with over 750 million people still lacking access to electricity, and more than 2.1 billion people remain without access to clean cooking. Rising urbanisation and living standards are reshaping energy demand, with air conditioning alone expected to be one of the largest contributors to electricity demand growth in the coming decades. This reveals the sector’s increasing need to not only produce more energy but to produce it in a way that is equitable and sustainable.

In this context, ADIPEC 2025 is being held under the theme of ‘Energy. Intelligence. Impact’. It reflects a simple but powerful truth: meeting the world’s growing need for secure, affordable and sustainable energy will depend on how intelligently we harness every resource – human, technological and natural – to deliver meaningful results for economies and communities alike.

At its core, the theme recognises that intelligence – both human and artificial – is transforming the way energy is produced, managed, and consumed. From AI-driven optimisation and digital integration to advances in hydrogen, LNG, and decarbonisation, intelligent innovation is reshaping the global energy landscape. ADIPEC serves as the meeting point for these forces, where ideas translate into action and impact can be measured in investment, policy, and progress.

AI is a major topic of discussion in the context of energy, due to its high demand. How is ADIPEC responding to the challenges and opportunities of the AI-energy nexus? 

Artificial intelligence is reshaping both global energy demand and the industry’s ability to respond. Data centres already consume around 1.5% of global electricity, and with AI workloads, that demand could more than double by 2030, rising from 415 TWh to 945 TWh. A single advanced AI model can require as much electricity to train as 100 households use in a year, while an AI query may consume 10 times more energy than a standard search.

This convergence is both a challenge and an opportunity. AI requires enormous energy, but it can also optimise grids, cut waste, improve operational efficiency, and accelerate decarbonisation. At ADIPEC 2025, we have expanded our AI Zone into five experiential areas showcasing how AI is transforming systems, people, and infrastructure. Alongside this, more than 80 conference sessions are dedicated to the AI–energy nexus, from predictive analytics to governance frameworks.

For Africa, this is particularly significant. Many countries are rapidly digitalising while also expanding power systems. The ability of AI to enhance reliability and reduce costs could be transformative for energy access and economic growth.

How is the diversity of the African continent and its vast energy sector reflected across ADIPEC 2025’s programme? 

Africa is a core part of ADIPEC’s community. This year, we are proud to welcome a strong delegation of African ministers and leaders, including those from Nigeria, Kenya, Uganda, Sierra Leone, Zimbabwe, Gambia, Equatorial Guinea, and Egypt. Their participation enriches ADIPEC’s Strategic Conference and exhibitions, ensuring Africa’s perspectives are reflected in discussions on natural gas, hydrogen, downstream, and low-carbon solutions.

dmg events is also the largest organiser of energy and infrastructure events across Africa, with long-standing operations in Nigeria, Mozambique, Kenya, Ethiopia, Ghana, Tanzania, South Africa, Egypt and Morocco. This presence gives us a unique vantage point to bridge African priorities with global dialogue.

Africa holds some of the world’s largest reserves of natural gas, oil, and minerals, as well as enormous potential in renewables. ADIPEC is committed to supporting this potential by convening African voices alongside global leaders, unlocking partnerships that can expand access, accelerate industrialisation, and strengthen Africa’s contribution to global energy progress.

Some of ADIPEC 2025’s notable African speakers include: Honourable J. Opiyo Wandayi, Cabinet Secretary for Energy and Petroleum, Kenya; Honourable Sen. Dr. Heineken Lokpobiri, Minister for State (Oil), Petroleum Resources, Nigeria; Rt. Honourable Ekperikpe Ekpo, Minister for State (Gas) Petroleum Resources, Nigeria; Honourable Chief Adebayo Adelabu, Minister of Power, Nigeria; Honourable Julius D.
