The Congo LNG project by Eni advances to Phase 2 with gas introduced into the new offshore infrastructure system and the Nguya FLNG floating liquefaction unit ready to support operations

Moving ahead of the schedule as a result of rigorous industrial planning, Eni is aiming export of the first LNG cargo early next year. 

Alongside the FLNG unit for liquefaction and export, the project's massive capacity of 3 mn tonnes per annum will be supported by three production platforms, and the Scarabeo 5 unit dedicated to gas treatment and compression.

Linked to the offshore Nené and Litchendjili fields in the Marine XII license, the integrated configuration will develop vast gas resources from the region, tackling the volumes in a phased manner to ensure flexibility and a steady flow to both the Tango FLNG unit, operational since late 2023, and the Nguya FLNG. 

A work of technological innovation, the 376m-long and 60m-wide Nguya FLNG is an optimised and sustainable unit that not only process gas with varried compositions but can also support additional field development.

Meanwhile, the Scarabeo 5 unit too is equipped with decarbonisation-oriented solutions. The unit was repurposed from a drilling rig into a gas treatment, separation, and compression unit. 

Carried out majorly in Congo, the project was largely led by local stakeholders. 

 

The plant will play a pivotal role in advancing Angola as a global natural gas player.

The New Gas Consortium's Gas Treatment Plant in Soyo, northern Angola, has been inaugurated by NGC operator, Azule Energy, a joint venture between Eni and bp

The inauguration was attended by the President of the Republic of Angola, João Gonçalves Lourenço, alongside the Minister of Mineral Resources, Petroleum and Gas, Diamantino Azevedo, and the Chairman of the Board of Angola’s National Oil and Gas Agency (ANPG), Paulino Jeronimo.

Initially led by Eni before the Azule Energy was formed, the NGC project is the country’s first non-associated gas development, with a processing capacity of approximately 400 mn standard cu/ft of gas per day (MMscfd) and 20,000 barrels of condensate per day. Gas is sourced from the offshore Quiluma and Maboqueiro fields, treated and then supplied to the Angola LNG plant for export and domestic consumption.

The plant will play a pivotal role in advancing Angola as a strategic player in the global natural gas market, while also supporting the country's energy diversification and responsible resource development, enabling growth in other key sectors such as fertiliser production for agriculture.

The gas treatment plant entered the commissioning phase with gas in November 2025, marking the beginning of operations for the NGC project. The project was delivered in a record 24-months, six months ahead of the sanctioned schedule.

The New Gas Consortium is operated by Azule Energy with 37.4% participation, in partnership with Cabinda Gulf Oil Company (CABGOC) with 31%, Sonangol E&P with 19.8%, TotalEnergies with 11.8%, and ANPG as the National Concessionaire.

The survey and support-to-installation contract is worth around €8.5mn.

The Bouri Gas Utilisation Project development in Libya that aims valourising the associated gas from the Bouri field will involve work class ROVs performing offshore touch down monitoring 

Specialised vessels by Next Geosolutions called NG Worker and NG Surveyor will be deployed for the operations in line with around €8.5mn-worth survey and support-to-installation contract awarded by Saipem. 

A significant project including complex construction and pipelines delivery, Saipem will be handling the installation of a new Gas Recovery Module, along with a series of upgrades and enhancements to the existing infrastructure. Its contract with Next Geosolutions include optional extensions following operations in Q4 2025. 

NextGeo, which mainly deals in renewables and subsea power cables, is excited to have stepped into the oil & gas segment with this significant project from North Africa. It is an addition to another major contract from the same project that was landed last July by the company's affiliate Rana Subsea. Valued at approximately €62.6mn, the contract mandates Rana Suibsea to provide specialised subsea services and installation support operations, extending through Q2 2026.

Giovanni Ranieri, CEO of Next Geosolutions, said, “The award of these new contracts with Saipem marks a significant step forward in the growth path of our Group. The joint presence of NextGeo and Rana Subsea in the same project clearly demonstrates the full complementarity of our expertise and our ability to operate in synergy across different yet closely integrated activities, positioning ourselves as a single, trusted partner for the development of complex projects. This is a collective achievement that strengthens our Group identity and represents a natural evolution towards an increasingly integrated, competitive, and operationally excellent model.”

Partners target 350 mn standard cu/ft of gas per day at peak production.

The HI gas development offshore Nigeria will push ahead as Shell-subsidiary, Shell Nigeria Exploration and Production Company Limited, and Sunlink Energies and Resources Limited, have taken a final investment decision (FID) on the project 

The partners target 350 mn standard cu/ft (approximately 60 thousand barrels of oil equivalent) of gas per day at peak production, which will be supplied to Nigeria LNG (NLNG; Shell interest 25.6%) -- a primary producer and exporter of liquefied natural gas (LNG) to global markets. Production is expected to begin before the end of this decade.

“Following recent investment decisions related to the Bonga deep-water development, today’s announcement demonstrates our continued commitment to Nigeria’s energy sector, with a focus on Deepwater and Integrated Gas,” said Peter Costello, Shell’s Upstream President. “This Upstream project will help Shell grow our leading Integrated Gas portfolio, while supporting Nigeria’s plans to become a more significant player in the global LNG market.”

The increase in feedstock to NLNG, via the Train 7 project that aims to expand the Bonny Island terminal’s production capacity, is in line with Shell’s plans to grow its global LNG volumes by an average of 4-5% per year until 2030. It will also bolster NLNG’s contribution to Nigeria's national economic development goals, including jobs in construction and operations.

The HI field was discovered in 1985 and lies in 100m of water depth around 50km from the shore. The current estimated recoverable resource volumes of the HI project are approximately 285 mmboe (million barrels of oil equivalent).

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.
