In oil and gas, a discovery is important — but the real value comes from what happens next. For Afentra plc (LSE:AET), the successful Pacassa SW discovery in Angola is now being followed by a series of development, production and portfolio milestones that could make the second half of 2026 an important period for the company.
In a recent Watch List interview, Paul McDade, CEO of Afentra plc, outlined the significance of the discovery, the company’s growing position in Block 3/05 and the range of offshore and onshore opportunities now moving forward.
Pacassa SW Discovery Marks a Major Milestone
The Pacassa SW well represents the first well delivered on Block 3/05 in more than a decade, making the result particularly significant for Afentra and its partners.
The well encountered 136 metres of net oil pay within a gross 217-metre hydrocarbon-bearing interval, with the reservoir demonstrating good quality and strong indications of communication with the main Pacassa field. The results are consistent with Afentra’s pre-drill geological model and support the company’s view of the wider Pacassa SW opportunity.
Afentra estimates that the wider Pacassa SW structure has the potential to contain up to 70 million barrels of gross recoverable resources, equivalent to approximately 23 million barrels net to Afentra, subject to further technical evaluation and the completion of the reserves and resources assessment.
For a company of Afentra’s size, that potential is substantial.
As Paul McDade explained, the discovery also benefits from its proximity to existing infrastructure. The Pacassa SW well is being completed as a production well and connected to the existing Pacassa production system, creating a potentially rapid route from discovery to cash-generating production. First oil is expected during Q3 2026.
That ability to utilise existing infrastructure is particularly attractive, as it can help keep development costs and timelines under control while accelerating the potential contribution from the new discovery.
Production Growth Moving Into Focus
Pacassa SW is not the only source of near-term production potential.
Afentra has also successfully restarted the Impala-1 well, which had been shut in since 2017. Following a light well intervention, the well achieved gross flow rates of up to approximately 4,700 barrels of oil per day during testing and is currently producing at around 3,000 barrels per day gross, with production intentionally constrained to manage water cut and longer-term reservoir performance.
The restart provides immediate production while also generating valuable reservoir and well productivity data ahead of the planned Impala-2 development well.
Impala-2 is expected to follow the Pacassa SW operations, with drilling anticipated to begin later in 2026 and results expected towards the end of Q4.
Together, Pacassa SW, Impala-1 and Impala-2 create a series of important offshore catalysts for Afentra.
Growing Exposure to Block 3/05
The company’s broader strategy is also being supported by the anticipated completion of the Etu transaction, which is expected in Q3 2026.
The transaction will increase Afentra’s interest in Block 3/05, providing greater exposure to the production and development opportunities across the asset.
That is important because the company is increasingly demonstrating the ability to unlock value from mature Angolan assets through a combination of targeted drilling, workovers, redevelopment and operational optimisation.
Rather than relying solely on large-scale exploration success, Afentra is pursuing a pragmatic strategy focused on assets where existing infrastructure and established production can help accelerate returns.
Further Opportunities Beyond Pacassa
The company’s growth ambitions extend beyond Block 3/05.
Afentra is also progressing its operated activities on Block 3/24, where it recently completed its first operated offshore campaign without incidents. An innovative approach to wellhead inspections reduced the survey cost by approximately 90%, demonstrating the company’s focus on disciplined capital allocation and cost-effective execution.
Onshore, Afentra continues to assess exploration opportunities across its Kwanza Onshore portfolio, with seismic interpretation beginning to identify potentially attractive targets.
The company is also progressing plans around the KON 4 Quenguela Norte field, providing another potential development opportunity within its growing portfolio.
A Busy Second Half of 2026
For shareholders, the key feature of Afentra’s current position is the number of potential catalysts progressing simultaneously.
Pacassa SW is moving towards production, Impala-1 has already returned to production, Impala-2 is approaching the drilling phase and the Etu transaction is expected to further strengthen Afentra’s position in Block 3/05.
At the same time, the company is advancing Block 3/24 and continuing to evaluate its onshore exploration and redevelopment opportunities.
The Pacassa SW discovery therefore represents more than a successful individual well. It provides further evidence that Afentra’s strategy of targeting mature African assets with production, infrastructure and redevelopment potential can generate meaningful organic growth.
As Paul McDade has highlighted, the discovery provides clear proof of concept for Afentra’s organic growth strategy.
With new production coming through, further drilling ahead and a growing portfolio of opportunities, Afentra plc is entering the next phase of its development with considerable momentum.
For investors watching the company, the focus now shifts from what Pacassa SW has discovered to how quickly Afentra can turn that discovery, alongside its wider portfolio, into production growth, enhanced cash flow and long-term value.
