Nigeria is increasingly looking towards developing its brownfield assets to boost production.
This can be achieved with the right technological interventions, giving way to enhanced oil recovery that can substantially meet the region's refining capacity. Compared to greenfield projects that require considerable investments from scratch, brownfield developments cuts down on carbon footprints, thus allowing operators to meet their sustainability requirements. Ideal technological interventions comprise a package offering e-line, slick line, coiled tubing services, well remediation, well control, and idle well management services. Well intervention operations can range from well conversion, casing run operation on a wild cat well, slot recovery, installation of emergency casing head housing slip, well work-over, and drilling and completion, to name a few.
To facilitate more brownfield developments, the Nigerian administration is working to increase collaboration between the local communities, government and the private sector.
Recently, Nigeria-based offshore construction company called Intrepid Energy Limited joined hands with United Kingdom's Aquaterra Energy to deliver a bespoke subsea well intervention equipment package for a project in Nigeria.
“Working with Aquaterra Energy marks a significant step forward for our intervention operations in Nigeria. Their specialised technology enhances our ability to execute intervention programmes efficiently, maximising performance across our assets. By combining Aquaterra’s technical expertise with our deep understanding of the local operating environment, we’re confident this collaboration will enhance production outcomes and create lasting value for our operations in the region,” said Seun Alonge, CEO at Intrepid Energy Limited.

In a major realisation of its production and cost optimisation objectives, the Nigerian National Petroleum Company (NNPC), along with joint venture partner First Exploration & Petroleum Development Company (First E&P), has announced a significant hydrocarbon discovery in the Songhai field, located in OML 85 in the shallow offshore region of Bayelsa.
Spudded as part of efforts to increase and sustain the joint venture's oil production over the next five years, the well was drilled to a total depth of 8,883 feet measured depth (MD) in 30 metres of water. It encountered hydrocarbons across eight reservoirs, logging over 1,000 feet of hydrocarbon-bearing sands, most of which reveals promising reservoir properties. There has been an indication of substantial oil and gas volumes for commercial exploration. The derived well data will now be integrated for thorough research and analysis to calculate resource estimates and optimise field development plans.
"This discovery marks a major milestone in our efforts to unlock the full potential of our assets. The success at Songhai Field underscores the effectiveness of our exploration strategy and our commitment to delivering sustainable value to all stakeholders," said Segun Owolabi, General Manager, Exploration and Development at FIRST E&P.
"This aligns with NNPC Limited’s mandate to drive production growth and cost optimization. The success at Songhai Field reflects our commitment to strategic partnerships, advanced technology, and efficient operations to maximize Nigeria’s hydrocarbon potential sustainably," said Seyi Omotowa, Chief Upstream Investment Officer of NUIMS. "The discovery also highlights the role of strategic collaboration in expanding Nigeria’s hydrocarbon reserves," he added.
"This discovery reaffirms the potential of Nigeria’s offshore assets and the importance of collaboration in boosting reserves and production. NNPC Limited remains committed to driving efficiency and long-term value creation for the nation," said NNPC’s Group Chief Executive Officer, Mallam Mele Kyari.
Following 2024's extensive eight-well production drilling campaign in the Dussafu Marin permit offshore Gabon, operator BW Energy and partner Panoro Energy have managed to hit their production targets of 40,000 barrels of oil per day (bopd) in November 2024, and has remained consistent since.
This was made possible by a robust workover and electrical submersible pump replacement programme with the help of Borr Drilling's Norve jack-up rig. An effective artificial lifet method, ESPs help pump production fluids from low pressure situations. It is easy to maintain, and is considered a cost effective alternative to vertical turbine, split case and positive displacement pumps.
At approximately 37,153 bopd in the fourth quarter of 2024, the site crossed a milestone as it was the highest quarterly rate achieved since 2018, when the block first started producing.
The current production rate might jump by another 10%, given the scope for the FPSO nameplate capacity to reach beyond 40,000 bopd.
After the 2024 production campaign concluded in October, with the installation of a conventional electrical submersible pump (ESP) system for the DHIBM-7H well as it was brought online, the rest of the seven Hibiscus / Ruche production wells also underwent a workover and ESP replacement programme in January this year.
According to Panoro Energy's Chief Executive Officer, John Hamilton, the Dussafu drilling campaign was expanded to eight wells in order to accomodate first track development of the final two discoveries made in May 2024.
“Our current focus is on fully transitioning all the new wells to conventional ESP systems and restoring production at the three shut-in wells, after which we will drill the exciting Bourdon prospect in line with our infrastructure lead exploration and appraisal strategy aimed at unlocking the substantial organic upside that exists on the block,” said Hamilton, while speaking on the drilling campaign.
As part of its 2025-26 programme in Gabon, Borr Jack-Up XIV Inc will be deployed by Vaalco Energy for the drilling of multiple development wells and appraisal/exploration wells.
"We are excited about the major projects planned for 2025 that are expected to deliver a step-change in organic growth across our portfolio in the coming years. In Gabon, we continue to work with our joint owners at Etame on our shared goal of executing another successful drilling campaign designed to enhance production and add reserves. We have signed a contract with Borr that we believe allows us the flexibility to optimise our drilling and workover plans offshore Gabon.
“We anticipate the programme to begin in mid-2025 with the sequencing and exact number of wells yet to be finalised. We are planning on multiple wells in the Etame field, multiple wells at our SEENT platform and a redrill and several workovers in the Ebouri field to access production and reserves that were previously shut in and removed from proved reserves due to H2S. Over the past three years, we have delivered on our focused strategy and believe we will continue to do so with the organic growth programmes across our diversified portfolio over the coming years,” said George Maxwell, the Chief Executive Officer of Vaalco Energy.

On January 15, 2025, Chevron has announced that it did not find commercial hydrocarbon reserves in its exploration well, Kapana 1X, located in Namibia’s Orange Basin within the PEL90 block.
Despite the absence of viable reserves, the company emphasised that the well provided valuable geological data, enhancing its understanding of the basin. Chevron indicated that it plans to continue exploring Namibia in the future, as the country remains a key area of interest for oil producers.
Namibia has recently become a hotbed for offshore oil discoveries, with several large-scale finds making headlines as some of the biggest of the century. However, not all exploration efforts have been successful. Last week, Shell revealed a US$400 million write-down on an offshore discovery in Namibia, deeming it commercially unviable.
In a separate development, Namibia’s national oil company announced in April that it had entered into a deal with Chevron, granting the US company an 80% operating working interest in an offshore block in the Walvis Basin, marking a new phase in Chevron’s involvement in the country’s energy sector.
Shell Nigeria Exploration and Production Company Limited (SNEPCo), a subsidiary of Shell plc, has reached a final investment decision (FID) for the Bonga North deep-water project off Nigeria’s coast.
This subsea tie-back will connect to the Shell-operated Bonga Floating Production Storage and Offloading (FPSO) facility, where Shell holds a 55% interest.
The Bonga North project encompasses drilling and starting up 16 wells—split equally between production and water injection wells—alongside upgrades to the Bonga Main FPSO and new subsea hardware installations. The initiative aims to sustain production at the Bonga facility, with recoverable resources estimated at over 300 million barrels of oil equivalent (boe). Peak production is expected to reach 110,000 barrels of oil per day, with first oil anticipated by the decade's end.
Zoë Yujnovich, Shell’s Integrated Gas and Upstream Director, described the project as a significant investment contributing to stable liquids production and reinforcing Shell’s Upstream portfolio. Bonga North’s development aligns with Shell’s strategy to drive cash generation through its Integrated Gas and Upstream business into the next decade.
SNEPCo operates Bonga North in partnership with Esso Exploration and Production Nigeria Ltd. (20%), Nigerian Agip Exploration Ltd. (12.5%), and TotalEnergies Exploration and Production Nigeria Ltd. (12.5%), on behalf of the Nigerian National Petroleum Company Limited (NNPC). Situated in OML 118, Bonga is a deep-water field with production beginning in 2005. It achieved its one-billionth barrel milestone in 2023, and the FPSO has a production capacity of 225,000 barrels of oil daily.
Bonga North’s recoverable volumes exceed 300 million boe, classified as proven and probable (2P) under the Society of Petroleum Engineers’ standards. The project is also expected to surpass Shell’s hurdle rate for its Upstream business, leveraging near-field opportunities, technical expertise, and simplified, replicable operational models.
